Description

Printing equipment, print instruction apparatus and print system

Technical field

The present invention relates to printing equipment, print instruction apparatus and print system, the storer that particularly relates to the print buffer of interim storaging printing data discharges control technology.

Background technology

In the past, in the print system that connects with network, (following also note is made " image processing system " by printing equipment, " printer ") (following also note is made " file and picture feedway " to print instruction apparatus, " main device ") ask the transmission of print data to be called " drawing " mode (Pull mode), in the print system of this Pull mode, print data is stored in the print buffer with file and picture feedway, when image processing system is carried out printing, the print data of necessity is sent the request of transmission to above-mentioned file and picture feedway whenever needs the time, receive necessary print data and also print.

In this print processing, the file and picture feedway need be deleted the data of not wanting in the print processing at any time, effectively utilizes print buffer.

In the storer releasing control method of the print buffer of in the past carrying out, a kind of method is, image processing system sends the transmission request of print data to the file and picture feedway, when the file and picture feedway has received the transmission response, this response is to carry out when receiving end again, this print data is deleted from print buffer, or another kind of method is, print system as " pushing away " mode (Push mode), when the file and picture feedway judges that print data is transmitted end, this print data is deleted from print buffer.

For example, as shown in Figure 1, under the situation of print data being carried out frequency band (band) processing, with the 1st frequency band, the 2nd frequency band ... print data alternately store among raster memory A shown in Figure 2, the B, when the print data of the 1st frequency band transmits end, delete the print data of the 1st frequency band, the print data of the 3rd frequency band is stored among the raster memory A; When the print data of the 2nd frequency band transmits when finishing, the print data of deleting the 2nd frequency band stores the print data of the 4th frequency band among the raster memory B into, carries out above-mentioned processing so repeatedly.Fig. 3 be illustrate with the frequency band data store raster memory into, the figure of the timing that transmits, delete.

In the print system of such Push mode, the print data of file and picture feedway in order to want to the image processing system transmission to print, and after print data was transmitted end, the file and picture feedway was no problem from this print data of print buffer deletion.

Yet along with popularizing of office networkization, the printer corresponding with network obtained extensively popularizing.From now on, family is also in the networking of marching toward, and what can imagine is that the printer corresponding with the network of family will be popularized.And, as the network in network printing, be not only LAN (Local AreaNetwork: LAN (Local Area Network)), will be object with the Internet also in the past.

At this,, be reference formula printing (Print ByReferrence) mode (in this manual, hereinafter referred to as the PBR mode) as the network printing mode one of them.In the PBR mode, main device promptly is the server of print data, send to printer and to have specified URL (UniformResource Locator: printing indication URL(uniform resource locator)), the printer of having accepted to print indication obtains data and prints from the specified Web server of URL.

At this, when the data on the Internet of specifying with URL, also can print the data on the Internet.

The advantage that the PBR mode has is even never have the main device that the Internet connects function, also can print the data on the Internet.In the main device of cheapness, it is difficult that the Internet that install to increase a main cause of cost connects function, and also can realize the printing function of data on the Internet from so main device, and therefore, it is to envision that the PBR mode can extensively be popularized from now on.

At this, having as the representative of ipp becomes RFC (Request ForComments, anticipate promptly: the ipp of the standard agreement of defined (Internet Printing Protocol) (in this manual hereinafter referred to as IPP) Request for Comment), even also regulation has the printing-URI based on the PBR mode to ask (URI: universal resource identifier, Uniform Resource Identifier) in IPP.About utilizing the action of IPP, carry when having specified " printings-URI request " of URL to printer when main device, accepted the printer of this " printing-URI request ", acquisition on the Web server in URL appointment place data and print.By this printing-URI function, can realize printing the data on the Web server in the world.

As print data corresponding to the printer of PBR mode, have following several: with postscript sign indicating number (PostScript) is that the page or leaf of representative is recorded and narrated the described data of language, be the described data of printer control language of representative, beyond the view data compressed by JPEG (joint photographic experts group) (JPEG) etc., is the described data of mark (markup) language (hereinafter referred to as mark (markup) data) etc. of representative in addition with HTML (HTML) with printer control language (PCL:Printer Command Language).

At this, in flag data, can be to be described from other data of data internal reference, in the PBR mode, when the assigned tags data print indication as print data, if with reference to the data that can become print object in the flag data of appointment, then be not only flag data, comparable data also becomes print object.

In addition, with the corresponding print system of PBR in, this three parts is relevant with client, printer, Web server, can make exist respectively separately each the device in.Client and Web server can be installed in the main device, constitute thereby can become the system that is connected with print apparatus.On system constitutes, because only there are 2 devices, so, later on this system's formation is called the two system in this manual.These two system's reason master device and print apparatus constitute, thus identical with the formation of the common pairing print system of LAN, also printing equipment directly can be used as the pairing printer of LAN with the Internet printing of PBR mode.

In addition, in technology in the past, the example (for example, with reference to patent documentation 1) with the two system of PBR mode is arranged also.In patent documentation 1,, realized printing-URI request at IPP as the agreement of PBR.

In the past in the two system in the example, main device will specify the URL of the print data in installing to be sent to printer in printing-URI request at this.Printer is determined to visit the Web server of main device from after in the main device of print data on network of URL, downloads the print data of appointment and prints.

Fig. 4 illustrates this process flow diagram (with reference to Fig. 7 of patent documentation 1) of the data processing sequence of movement in the main device in the example in the past.In addition, below the timing that the data of stressing relevant print data are transmitted and delete will be carried out schematic illustration about content in addition.

At first, in step S9001, when not starting the Web server of print data transmission usefulness, start Web server (S9002).

Then, print the login (S9003) of data, and print the management (S9004) of data.

Then, when having accepted from printer, judge that whether it is the 1st the Pull request (S9005) to print data to the Pull of data request (download request).

When being the 1st Pull request, accepting Pull request (S9006), and print data is write in reply to printer (S9007).

Then, judge whether the transmission of print data finishes (S9008), when the transmission of judging print data has finished, transfer to step S9009,, stop Web server (S9010), end process (S9011) from deleting this print data in the device certainly.

Generally speaking, in the PBR mode, there is not relevant regulations for the timing of deleting the print data on the Web server.IPP exists with ... installation too.

Generally speaking, in the two system of PBR, main device is deleted the print data in device after the printout of confirming printer finishes.Because printout finishes, just do not need print data naturally.

At this, in the print processing of print engine, wait other processing to compare with the print data transmission, need a lot of time.If when print data is saved in the printout end, main device will can not discharge the print data buffer device that is used for storaging printing data (RAM (Random Access Memory: random access memory) etc. working storage), the high-level efficiency of system resource and effectively apply flexibly difficulty for a long time.

To this, in example in the past, in a single day having downloaded print data once with printer is prerequisite with regard to not downloading once more, when main device finishes the back in the transmission of print data, is judged as not print data, and deletion.

In this example in the past, the purpose of desiring to reach is: compared with the end of printout, because the transmission of print data can finish quite early, therefore can discharge the print data buffer device of storaging printing data as soon as possible, can be provided to processing beyond printing with timing early to the system resource of main device, thus high-level efficiency and applying flexibly effectively.

Patent documentation 1: TOHKEMY 2002-202874 communique

Yet, in the storer releasing control method of the print system of the Pull mode that in the past just had, for example, will be as the document the HTML content on the Internet during as the situation of document printing, to be used multiple times be very common to same image object in a document printing.

At this moment, from the file and picture feedway the 1st time view data is sent to image processing system, also can sends the transmission request of same image once more to the file and picture feedway from image processing system even be through with.In the storer releasing control method of in the past Pull mode, when the 1st time transmission finished, this view data was deleted, and becoming can not corresponding the 2nd later transmission request.

In the case, in the print system of in the past Pull mode, the printing target that transmission request more than 2 times is arranged, owing to deleted from print buffer, so the file and picture feedway is for the transmission request of the printing target in the image processing system, the one, bear the load that prints target once more and generated, or can not be corresponding with the transmission request of the printing target of image processing system.

Even the print system of the Pull mode that print data might be asked once more, when print job finishes owing to can discharge print buffer, as long as it is just no problem to guarantee to store whole print buffer of minimum 1 necessary print data of print job as far as possible, but when the capacity of print buffer is inadequate, then become the situation that new print data can not be stored into after print data transmits in the impact damper, transmit thereby can not do continuously to print data.

Promptly, have such problem in technology in the past: the result with deleting printing data as early as possible is, under the situation that print data is asked once more, must generate print data once more and store in the print buffer, thereby cause when the situation of the request once more of print data load excessive.

In the PBR mode,, can not guarantee not carry out download request once more though printer has been downloaded print data.This also is same in the PBR of the two system.Whether download the installation that will exist with ... printer once more.

In the PBR mode, download if can apply flexibly well once more, also can realize high function even only hold the cheap printer of system resource (RAM etc.) seldom.

One example explanation below is shown.That is the situation that view data is alternately printed in printer.In the formation that with the ink-jet printer is the line printer of representative be, in the print data buffer device, only store printhead and scanned necessary print data, and print processing, owing to adopted such formation, can realize reducing the storage space of print data buffer device, therefore, realize low price.

At this, be proposed in the rotating print function that the line printer of printing in the PBR mode is realized image.The simplest method is: download images data integral body, the view data global storage in the print buffer of printer, is rotated the method that prints by making it.If adopt the method, only need to download once, need not to download once more.Yet under normal conditions, the size of view data is very big, needs jumbo print buffer storer if will store the integral body of data, thereby causes the increase of cost, can not realize cheap printer.

To this, the method for rotating print is: in the view data of having downloaded, make in printhead scanning needed or be stored in data rotation in the print buffer of low capacity as much as possible, and the method that prints of storage.In the method, image rotating can not make for 1 time, need carry out " download-rotation " of view data repeatedly thus it is rotated prints, thereby realize the rotating print of image.Under the situation of the method,,,, also can realize high function like this as rotating print figure even have only the line printer of cheapness of the print data buffer device of low capacity though need repeatedly download for identical print data.

Like this, as long as print data is downloaded in the network printer of PBR mode once more, just can realize high function with the formation of cheapness.

Yet, such problem is arranged: in above-mentioned main device data processing in the past, can not be corresponding from printer download request once more, can not print data continuously and download necessary print processing once more thereby cause.

And, there is such problem: if when the printout that the two system was carried out with general PBR finishes, delete the mode of print data, though can with download once more corresponding, for the high-level efficiency of the system resource of storaging printing data and effectively apply flexibly the difficulty that then becomes.

Promptly, the problem that exists is: in technology in the past, delete the result of print data prematurely, under the situation of the request once more that print data is arranged, must generate print data once more and store in the print buffer, therefore the overload under the situation of the request once more that print data is being arranged is big, or in print buffer the print data holding time long.

Print engine 1201 is printed on document printing on recording chart etc.Rasterizer 1202 is the set of document printing as each point, and is deployed on its raster data that shows.Interpretive routine 1203 prints the parsing of data of description (homepage), this printing data of description is the mother stock data that constitute document printing, and will output on the file and picture feedway 1100 as the transmission request of the image object of subfraction certificate, wherein the subfraction is according to being to constitute rasterizer 1202 needed document printing.I/F1204 is by transfer medium 1300 in communication, to above-mentioned printing data of description or, image object, transmission request etc. carry out transceiver.

At this, in the time will printing document printing 1400 shown in Figure 6, the data that application program 1101 is held are converted into the printing data of description in printer 200P shown in Figure 7, this printing data of description is to describe with the language that can handle (at this is the XHTML form, also claims the ML form); The target that the data of being held with application program 1101 are linked, be converted into the printing target, this printing target is the image object (JPEG, PNG etc.) that can show etc., and the printing data of description that will be converted respectively and print target and store in the print buffer 1105.Print data has expression to print the situation of data of description, also has expression to print the situation of target.

With the document printing among Fig. 6 1400 is example, and document printing 1400 comprises: print data of description 1404 and 3 image objects 1401,402,403, image object 1401 and 403 is linked as same image object.Printing data of description 1404 is divided data (mother stock data) of the homepage of expression document printing 1400, according to request, be sent to the communication I/F1204 of image processing system 1200 from the communication I/F1104 of file and picture feedway 1100 from image processing system 1200.When having accepted printing data of description 1404, interpretive routine 1203 prints the parsing of data of description 1404, and the transmission request of the image object 1401,1402,1403 that rasterizer 1202 is required outputs to file and picture feedway 1100.And, when interpretive routine 1203 prints 1404 parsing of data of description,, judge whether to obtain once more the necessity of image object in order to finish the printing of image object 1401,1402,1403.

When Printer Engine 1201 printed according to the printing data of description 1404 of representing document printing 1400,1202 arrows as shown in Figure 8 of rasterizer sequentially carried out rasterisation along 1451～1461 from last beginning.When rasterisation is carried out in the zone of arrow 1451～1461, then need image object 1401, before will carrying out rasterisation to arrow 1451, the transmission request that rasterizer 1202 is sent image object 1401 to file and picture feedway 1100 receives image object 1401 at once.Then, when rasterisation is carried out in the zone of arrow 1455～1457, then need image object 1402, before will carrying out rasterisation to arrow 1455 at once, the transmission request that rasterizer 1202 is sent image object 1402 to file and picture feedway 1100 receives image object 1402.Then, if when carrying out rasterisation in the zone of arrow 1458～1461, then need image object 1403, but, because image object 1403 is identical with image object 1401, then needs image object 1401 once more, and once more file and picture feedway 1100 is sent image object 1401 and transmit request, receive image object 1401, the rasterisation in beginning arrow 1458～1461 fields.

And, when carrying out the rasterisation of image object 1403, image processing system 1200 is installed cache memory, when in above-mentioned cache memory, maintaining image object 1401, and the transmission requirement that nature needn't send image object 1401 to file and picture feedway 1100.

In the document printing 1400 of Fig. 6, about image object 1401 (front.jpg), because 1100 requests of 1200 pairs of document supplyings of image processing system transmit for 2 times, when the 1st time transmission finishes, under the situation that image object 1401 is deleted from print buffer 1105, since file and picture feedway 1100 can not corresponding the 2nd time the transmission request, thereby can not will from print buffer 1105, delete the opportunity of the opportunity of print data as the notice that the end of transmitting is arranged, this transmission is the transmission from image processing system 1200 to file and picture feedway 1100.

For this reason, for the target of relevant document printing 1400, image processing system 1200 bases processing sequence as shown in Figure 9,1203 pairs of file and picture feedwaies 1100 of rasterizer 1202 or network interpretive routine print the not notice of target.

At first, interpretive routine 1203 is resolved the printing data of description 1404 (S1101) that sends from file and picture feedway 1100.Then, rasterizer 1202 is carried out the preparation (S1102) of rasterisation, judges whether to be linked at the data (S1103) of the printing target of printing data of description 1404.

Print when needs under the situation of target data, 1202 pairs of file and picture feedway requests of transmitting of rasterizer (S1104) receive the data (S1105) of printing target.Then, the data of the printing target of this reception are carried out rasterisation (S1106).On the other hand, in above-mentioned steps S1103, under the situation of the transmission request that does not need to print target, then the data of the printing target of 1202 pairs of receptions of rasterizer are carried out rasterisation (S1106).Rasterisation (S1106) afterwards, judge whether into document printing the end rasterisation of document printing (finish) (S1107).If then do not proceeded under the situation of rasterisation, judge whether to need to again proceed to the transmission request (S1108) of the printing target that receives till the current point for the end of document printing by the data of rasterisation.Under the situation of the transmission request of the printing target that does not need to receive once more, do not need the notice (S1109) of this printing target after file and picture feedway 1100 sent.

In addition, when not printing the notice of target, as the information of determining not print target, just can be suitable for so long as can determine the information of printing target, comprise: the bus of this printing target, with the combination of the relative bus of information of determining the print jobs such as print job ID that this target is comprised etc. in the information of this definite printing target that lists.And the not time point of notice that prints target also can be that the printing target that will need not the request that transmits once more stores the time point of not doing in the illustrated print buffer into.

And the judgement of being carried out at step S1108 is whether print data is in homepage and whether reference later on, when print data under the situation of not reference later on, is judged as the property of there is no need in homepage.In view of the above, in the long-time reservation of the mistake of generation that positively prevents to transship and print data, can promptly discharge print buffer.

On the other hand, file and picture feedway 1100, as shown in figure 10, judge with the order with following step: step S1201 generates print data; Step S1202 stores print data into print buffer; Step S1203 sends print job; Step S1204 judges whether the reception information from image processing system is the transmission request of print data; Step S1205, judge when reception information be not that print data transmits when asking, whether be the not notice of print data from the reception information of image processing system; Whether step S1206 judges when reception information is not the not notice of print data, be the print job end notification from the reception information of image processing system; Step S1207 when reception information is the transmission request of print data, is sent to this image processing system 1200 with this print data that is stored in the print buffer 1105; And step S1208, when reception information is the not notice of print data, discharge this print data storage area of print buffer 1105; The file and picture feedway 1100 that has received notice not can discharge the zone of this print data of storage by step S1205 and step S1208 from print buffer 1105, step S1205 judges whether the reception information from image processing system is the not notice of print data, and step S1208 discharges the storage area of this print data in the print buffer 1105 when reception information is not notifying of print data.

Figure 11 is illustrated in when printing document printing 1400 figure of the sequence of being carried out between file and picture feedway 1100 and image processing system 1200.

The application program 1101 of file and picture feedway 1100 and converter section 1102 are made printing data of description 1404, the image object 1401～1403 that constitutes document printing 1400, and store in the print buffer 1105.Application program 1101 is sent print request to 1103 requests of printer control part.

Printer control part 1103 will be printed data of description 1404, image object 1401～1403 signs in to inner management database and management.And printer control part 1103 is issued to the URI print request in the image processing system 1200 to not making the request of illustrated PBR client port.The PBR client port that has received request sends URI print request (S1501) by communication I/F1104 to image processing system 1200.

At this, send to image processing system 1200 according to the URI print request:

The URL of specifying print data

Print conditions

Simultaneously,

When the print data of file and picture feedway 1100 becomes unwanted data, send the request of prompting print state information.In present embodiment 1, specify printing data of description 1404 with URL.The transmission of this URI print request and its corresponding response receive and are carried out by the PBR client port.

Accept the illustrated task management of not doing of the image processing system 1200 of URI print request and sent operation, the corresponding job state record of the operation of making and sending, and login is on admin table.After the login, return the response (S1502) of URI print request by the PBR device port.

And, do not do illustrated print management and under the state of " date no need (not needing data) ", set internal state, so that in file and picture feedway 1100, print the state notifying incident at print state.

Then, from the specified print data of URI print request download URL (be actually and print data of description 1404), WEB client sends Pull request " Pull asks (topppage.xhtmlp) " (S1503) to file and picture feedway 1100 to the Web client requests in task management.

Accept the print control section 1103 of the file and picture feedway 1100 of Pull request, from print buffer 1105, taken out and print data of description 1404 (toppage.xhtmlp), sent back to image processing system 1200 (S1504).

Accepted to print the Web client of the image processing system 1200 of data of description 1404, by via task management, interpretive routine 1203 is given in handing-over, 1203 pairs of interpretive routines are printed data of description 1404 routine processes that makes an explanation, and be converted to DOM Tree (the Document Object Model: DOM Document Object Model), give the illustrated designing and calculating portion of not doing of expression document structuring.Designing and calculating portion is carrying out design-calculated simultaneously according to DOM Tree, determine to print the image object 1401～1403 of 1404 references of data of description.

Then, the designing and calculating radicals by which characters are arranged in traditional Chinese dictionaries are earlier to Web client requests download images target 1401 (front.jpg), and Web client sends Pull request " Pull asks (front.jpg) " (S1505) by communication I/F1204 to file and picture feedway 1100.

Accepted the printer control part 1103 of the file and picture feedway 1100 of Pull request, taken out image object 1401 (front.jpg) from print buffer 1105, I/F1104 sends to image processing system 1200 (S1506) by communication.

When having received image object 1401 (front.jpg), the Web client who has accepted joins to designing and calculating portion, and designing and calculating portion carries out rasterization process by rasterizer 1202, makes the output data of giving Printer Engine 1201.When finishing the making of output data, rasterizer 1202 sends it to Printer Engine 1201, Printer Engine 1201 print image targets 1401.

After the printing of image object 1401 finishes, designing and calculating portion is to Web client requests download images target 1402 (side.jpg), and Web client sends Pull request " Pull asks (side.jpg) " (S1507) by communication I/F1204 to file and picture feedway 1100.And, about image object 1401 (front.jpg), because in printing, need to utilize once more, so need not send the not notice of target (front.jpg).

Having accepted the printer control part 1103 of the file and picture feedway 1100 of Pull request, is to take out image object 1402 (side.jpg) from printing impact damper 1105, by communication I/F1104, sends to image processing system 1200 (S1507).

When receiving image object 1402 (side.jpg), carry out and the identical processing of situation that receives image object 1401 (front.jpg), Printer Engine 1201 print image targets 1402.And, about image object 1402 (side.jpg), in printing, need not to utilize once more, rasterizer 1202 or interpretive routine 1203 send the not notice (S1509) of target (side.jpg) by communication I/F1204.

In addition, this is not notified as the printer modes notification event and is sent out, and at this, the printer modes notification event is the printer modes field that state value " data no need (not needing data) " is recorded the printer modes record.

When receiving the printer modes notification event, printer control part 1103 is according to " data noneed (not needing data) " such incident reason, judgement can be deleted the image object 1402 that is stored in the print buffer 1105, thereby discharges the memory area (S1509) of memory image target 1402 in the print buffer 1105.

After the transmission of not asking of target finishes, the designing and calculating radicals by which characters are arranged in traditional Chinese dictionaries are earlier to Web client requests download images target 1403 (front.jpg), and Web client sends Pull request " Pull asks (front.jpg) " (S1511) by communication I/F1204 to file and picture feedway 1100.

Accepted the printer control part 1103 of the file and picture feedway 1100 of Pull request, taken out image object 1403 (front.jpg),, sent to image processing system 1200 (S1512) by communication I/F1104 from print buffer 1105.

When receiving image object 1402 (front.jpg), Printer Engine 1201 print image targets 1402.And, about image object 1403 (front.jpg), because in printing, do not need to utilize once more, thus rasterizer 1202 or interpretive routine 1203, by the not notice (S1513) of communication I/F1204 transmission target (front.jpg).

When receiving the printer modes notification event, printer control part 1103 is according to " data noneed (not needing data) " such incident reason, judgement can delete the image object 1403 that is stored in the print buffer 1105, be forn.jpg, thereby discharges the memory area (S1514) of storage front.jpg in the print buffer 1105.And, about printing data of description 1404, be judged as and can delete, discharge the zone of storage print data of description 1404, owing to do not need print data to transmit service, so stop Web server.

Afterwards, the designing and calculating portion of image processing system 1200 is by rasterizer 1202, and residual part printed in Printer Engine 1201, finishes the printing of document printing 1400.And interpretive routine 1203 or rasterizer 1202 send to the job state bag in the file and picture feedway 1100 to the request of PBR device port, and this job state wraps in and records " completed " on the job state field.1100 of file and picture feedwaies that received this job state bag learn that the printing of the document printing 1400 of image processing system 1200 finishes.

According to relevant formation, before the printing of document printing finishes, by send the not notice of print data to file and picture feedway 1100 from image processing system 1200, file and picture is supplied with 1100 and can not be transshipped, and can positively discharge print buffer 1105 rapidly, even the situation that buffer capacity is little also can be utilized print buffer 1105 expeditiously, thereby finish print job.
