The printing apparatus 1 of this embodiment will be described below with reference to FIGS. 1 to 6.

FIG. 1 is a diagram showing an example of the configuration of a printing system 10 according to the present embodiment. As shown in FIG. 1, the printing system 10 includes a printing device 1 and an external device 200. The printing device 1 is, for example, an MFP (Multi-Function Peripheral).

The external device 200 is, for example, a PC (Personal Computer), and has a display (not shown). External device 200 is communicably connected to printing device 1 .

[Printing device configuration]
As shown in FIG. 1, the printing apparatus 1 includes a controller 100, a print engine 4, an operation panel 110, and a communication interface (I/F) 150.

The controller 100 includes an ASIC (Application Specification Integrated Circuit) 102, an NVRAM (Non-Volatile Random Access Memory) 103, and a RAM (Random Access Memory) 104. NVRAM 103 and RAM 104 are examples of memories.

The ASIC 102 has a built-in CPU (abbreviation for Central Processing Unit) 101. ASIC 102, NVRAM 103, RAM 104, print engine 4, operation panel 110, and communication I/F 150 are electrically connected to each other by a bus.

The controller 100 performs general control over each part of the printing apparatus 1 . The NVRAM 103 stores various control programs and various settings for controlling the printing apparatus 1. Controller 100 controls print engine 4 based on a control program stored in NVRAM 103.

The RAM 104 is used as a work area from which various control programs are read and a storage area for temporarily storing image data. The RAM 104 is provided with a buffer 104A and a page memory 104B.

The buffer 104A is a storage area for temporarily storing various commands and various data received by the communication I/F 150. For example, print job data and preceding commands received by the communication I/F 150 from the external device 200 are temporarily stored in the buffer 104A.

The page memory 104B is a storage area for temporarily storing data generated by the controller 100. The page memory 104B temporarily stores, for example, accumulated job data generated from print job data.

The print engine 4 is a device for printing on a sheet (not shown) using an electrophotographic method. The print engine 4 includes an exposing device 41 , a developing device 42 , a transfer roller 43 , and a fixing device 6 .

The exposure device 41 scans and exposes the surface of a photosensitive drum (not shown) with a laser beam, thereby forming an electrostatic latent image on the surface of the photosensitive drum based on print job data. The developing device 42 forms a toner image on the surface of the photosensitive drum by supplying toner to the electrostatic latent image formed on the surface of the photosensitive drum.

The transfer roller 43 transfers the toner image formed on the surface of the photosensitive drum to the sheet by conveying the sheet conveyed from a feed tray (not shown) while sandwiching it between the sheet and the photosensitive drum.

The fixing device 6 includes a heating roller 61, a heater 62, and a pressure roller (not shown). The heating roller 61 heats the sheet. The heater 62 is made of, for example, a halogen heater, is disposed inside the heating roller 61, and heats the heating roller 61. The pressure roller and the heating roller 61 sandwich the sheet.

The fixing device 6 fixes the toner image formed on the sheet by sandwiching the sheet on which the toner image is formed between a heating roller 61 and a pressure roller and conveying the sheet while heating the sheet. As a result, printing is performed on the sheet based on the print job data.

The communication I/F 150 is connected to a network such as a LAN (Local Area Network), and enables connection with an external device 200 in which a driver for the printing device 1 is installed. The printing device 1 receives a preceding command, print job data, etc. from the external device 200 via the communication I/F 150.

The operation panel 110 is a user interface for accepting user operations. The operation panel 110 has a touch panel 111 and push buttons 112.

Note that although the printing system 10 in FIG. 1 is shown as having one external device 200, the present invention is not limited to this. For example, the printing system 10 may include two or more external devices 200. Furthermore, the printing system 10 may include an external device 200 other than a PC, such as a smartphone or a tablet.

[Processing by external device]
Next, the flow of processing by the external device 200 will be described with reference to FIG. 2. FIG. 2 is a flowchart showing an example of the flow of processing by the external device 200 of FIG.

The external device 200 determines whether the print button has been pressed by the user (S1). The print button is displayed on the display of the external device 200 and is used by the user to decide to perform desired printing.

When the print button is pressed (S1: YES), the external device 200 determines whether secure printing on and a password have been input on the driver setting screen (S2). Secure printing is an example of memory printing. A password is an example of authentication information.

If secure printing on and password are not input on the driver setting screen (S2: NO), the external device 200 creates option information including the user name and print job name (S3). The user name and print job name are examples of user information. Note that the print job name is not limited to the name of the print job, and may be any identification information that identifies the print job. The identification information of the print job may be, for example, a character string such as a number or ID.

On the other hand, if secure print on and password are entered on the driver setting screen (S2: YES), the external device 200 stores secure print on information and optional information including the user name, print job name, and password. (S4). It is assumed that the option information of the preceding command is written in, for example, Printer Job Language (PJL). Note that the external device 200 creates option information in S3 or S4 so as to include the parameters input on the driver setting screen. The parameter indicates the printing method described in the printer job language.

After S3, the external device 200 transmits the preceding command including the option information created in S3 to the printing device 1 via a LAN (not shown) (S5).

After S4 or S5, the external device 200 generates print job data including print content and printing method in print processing (S6). The print job data includes image data described in a page description language (PDL) as print content.

After S6, the external device 200 transmits the print job data generated in S6 to the printing device 1 via the LAN (S7). After S7, the external device 200 determines whether generation of all print job data has been completed (S8).

If the generation of all print job data is not completed (S8: NO), the external device 200 repeats S6 and S7 for each page, and if the generation of all print job data is completed (S8: YES), The flow of FIG. 2 ends.

[Flow of control by printing device]
Next, the flow of control of the printing apparatus 1 will be explained with reference to FIGS. 3 and 6. In FIG. 6, the printing apparatus 1 is divided into a communication I/F 150, a PJL analysis section, a RIP processing section, an engine control section, a motor control section, and a fixing device 6, and the processing executed by each section is illustrated. The PJL analysis section, the RIP processing section, the engine control section, and the motor control section are each functional blocks realized by the controller 100 executing various control programs.

As shown in FIG. 3, the controller 100 determines whether a preceding command transmitted from the external device 200 has been received via the communication I/F 150 (S11). If the preceding command is received (S11: YES), the PJL analysis unit of the controller 100 starts analyzing the preceding command by PJL analysis that analyzes the printer job description language (S12), as shown in FIG.

After S12, the controller 100 determines whether or not secure printing is performed (S13). In S13, the controller 100 determines that secure printing is being performed if the option information of the preceding command includes secure printing on information as information indicating secure printing. Note that the controller 100 may determine that the printing is secure printing if the option information of the preceding command includes a password. Further, in S3, the option information may include secure print off information. In this case, in S13, the controller 100 may determine that secure printing is being performed if the option information of the preceding command does not include secure printing off information.

If the controller 100 determines that the printing is secure printing (S13: YES), the process proceeds to S18. On the other hand, if the controller 100 determines that it is not secure printing (S13: NO), the controller 100 determines whether or not it is stored printing by determining whether storage printing ON information is stored in the NVRAM 103 (S14). .

The storage print on information is a setting value indicating the ON setting of storage print, which is an example of memory printing. It is assumed that the user turns on storage printing on the display screen of the operation panel 110. When the controller 100 is instructed to enable storage printing from the operation panel 110, the controller 100 causes the NVRAM 103 of the printing apparatus 1 to store storage printing ON information indicating that storage printing is enabled.

Note that the method for turning on storage printing is not limited to the above method. For example, the user may use a browser included in the external device 200 to access a web server included in the printing device 1, and turn on storage printing by operating a web page provided by the web server.

If the controller 100 determines that it is storage printing (S14: YES), the process proceeds to S18. On the other hand, if the PJL analysis unit of the controller 100 determines that it is not storage printing (S14: NO), it instructs the engine control unit to execute print preparation processing, and proceeds to S19.

If the controller 100 has not received the preceding command (S11: NO), the controller 100 determines whether or not reception of print job data has started (S15). If reception of print job data has not started (S15: NO), the controller 100 returns to S11 and waits for reception of a preceding command or print job data.

When receiving print job data is started (S15: YES), the controller 100 determines whether or not secure printing is performed by determining whether or not the received print job data includes secure print on information. Execute (S16).

When the controller 100 determines that the printing is secure printing (S16: YES), the process proceeds to S18. On the other hand, if the controller 100 determines that the printing is not secure printing (S16: NO), the controller 100 determines whether or not it is storage printing by determining whether storage printing ON information is stored in the NVRAM 103 (S17). .

Here, S13, S14, S16, and S17 correspond to a determination process in which the controller 100 determines whether the print job data being received in the reception process is to be subjected to memory printing.

If the controller 100 determines that it is storage printing (S17: YES), the process proceeds to S18, whereas if it determines that it is not storage printing (S17: NO), the process proceeds to S19.

Next, the accumulation process S18 in FIG. 3 will be explained with reference to FIG. 4. The PJL analysis unit of the controller 100 determines whether reception of the print job data transmitted from the external device 200 in S7 has been started (S30). If the reception of the print job data has not been started (S30: NO), the PJL analysis unit of the controller 100 returns to S30 and waits for the reception of the print job data. S30: YES), the received print job data is analyzed (S31) to obtain the user name (S32) and the print job name (S33).

Note that if the print job data does not include a user name, the user name is not acquired in S32. Further, if the print job data does not include a print job name, the print job name is not acquired in S33.

After S33, the controller 100 analyzes the received print job data (S31) to determine whether or not secure print on information has been acquired (S34), and if secure print on information has been acquired (S34: YES), obtains a password (S35), and proceeds to S36. On the other hand, if the controller 100 does not acquire the secure print-on information (S34: NO), the controller 100 does not acquire the password and proceeds to S36.

In S36, the controller 100 performs RIP processing as follows. That is, the controller 100 uses the RIP processing unit to rasterize the PDL format image data included in the print job data, thereby generating raster format print job data representing the image to be printed on the sheet, that is, the print content. do. PJL format parameters included in print job data include parameters used for rasterization.

Hereinafter, for convenience of explanation, the raster format print job data generated by the RIP processing unit will also be referred to as raster data. Raster data is data for each page, and if the print job data includes multiple pages, the controller 100 executes RIP processing for all of the multiple pages.

After S36, the controller 100 stores the RIP-processed raster data in the page memory 104B of the RAM 104 in association with the user name and print job name (S37). Here, the raster data accumulated in the page memory 104B is referred to as accumulated job data.

Note that in S37, if the controller 100 has received the preceding command (S11: YES), the controller 100 stores the accumulated job data corresponding to the preceding command in the RAM 104 in association with the user name and the print job name. Here, the user name and print job name acquired in S32 and S33 and stored in S37 correspond to identification information of print job data. Further, instead of the print job name included in the print job data, a print job name generated by the printing apparatus 1 may be stored in the RAM 104 in association with the stored job data.

With the above, the controller 100 completes the accumulation process S18 shown in FIG. 4, and ends the flow of FIG. 3. Note that if a user's operation is received via the operation panel 110 while waiting for reception of a preceding command or print job data, the controller 100 stores the stored job stored in storage processing S18. Print data. Furthermore, if parameters are associated with the accumulated job data, printing is performed using the parameters.

Specifically, in the case of stored printing (S14: YES) or (S17: YES), when the user inputs a user name via the operation panel 110, the controller 100 associates the user name with the input user name. Print stored stored job data. Note that the operation of inputting a user name may be an operation of selecting a user name displayed on the operation panel 110.

Furthermore, when the user inputs a print job name via the operation panel 110, the controller 100 may print accumulated job data stored in association with the input print job name. Note that the operation of inputting the print job name may be an operation of selecting the print job name displayed on the operation panel 110.

On the other hand, when secure printing is performed (S13: YES) or (S16: YES), when the user inputs a password via the operation panel 110, the controller 100 stores the accumulated information stored in association with the input password. Print job data.

Then, when the secure printing or storage printing is completed (S24: YES), the controller 100 ends the flow of FIG. 3.

As described above, in secure printing, the controller 100 stores print job data received from the external device 200 in the RAM 104, stores a password in the RAM 104 in association with the print job data, and then prints the password via the operation panel 110. When the password is input, the print job data stored in the RAM 104 is printed.

In addition, in storage printing, after receiving print job data from the external device 200, the controller 100 does not immediately execute printing, but stores the print job data in the RAM 104, and also stores a user name in association with the print job data. After storing the information and the print job name in the RAM 104, the print job data stored in the RAM 104 is printed when the user name or the print job name is received via the operation panel 110.

Next, the print preparation process S19 in FIG. 3 will be explained with reference to FIG. 5. If the printing is neither secure printing nor storage printing (S14: NO) or (S17: NO), the controller 100 executes print preparation processing (S19).

As a preparatory operation, the controller 100 starts driving a motor (not shown) (S41), starts rotating the heating roller 61, and sets the rotational speed of the heating roller 61 to a predetermined rotational speed.

Further, as a preparatory operation, the controller 100 starts raising the temperature of the fixing device 6 by heating the heating roller 61 with the heater 62 (S42).

Then, when the temperature of the fixing device 6 reaches a predetermined temperature range, the controller 100 stops driving the heater 62. Thereafter, the controller 100 repeatedly raises the temperature of the fixing device 6 and stops driving the heater 62 so as to maintain the temperature of the fixing device 6 within a predetermined temperature range. With the above steps, the print preparation process S19 ends.

Note that if the controller 100 does not receive a preceding command or print job data for a predetermined period of time after completing printing in S24, which will be described later, or if there is no print instruction, the controller 100 will keep the motor stopped. At the same time, even if the temperature of the fixing device 6 becomes lower than a predetermined temperature range, the heater 62 is kept stopped. It is assumed that the controller 100 raises the temperature of the fixing device 6 when receiving the preceding command or print job data again.

Returning to FIG. 3, after S19, the controller 100 determines via the communication I/F 150 whether or not reception of print job data has started (S20), and if reception of print job data has not started ( S20: NO), it is determined whether reception of print job data has started (S21). If reception of print job data has not started (S21: NO), the controller 100 returns to S21 and waits for reception of print job data.

If receiving the print job data has already started (S20: YES) or if receiving the print job data has started (S21: YES), the controller 100 lights up the operation panel 110 (S22). Here, a state in which power is applied to the operation panel 110 and the operation panel 110 lights up is an example of a first power state, which is a state in which power is not saved. Further, a state in which the operation panel 110 is turned off is an example of a second power state, which is a state in which power is saved more than the first power state. Note that the printing apparatus 1 is in the second power state during S15 to S18 described above.

In the first power state, power is being consumed due to the preparation operation being executed in the print preparation process S19. Further, in the second power state, the preparation operation is not executed in the print preparation process S19, and there is no power consumption associated with the preparation operation.

After S22, the controller 100 starts printing (S23). In S23, the controller 100 uses the PJL analysis unit to analyze the received print job data, as in S31, as shown in FIG. Subsequently, the controller 100 uses the RIP processing unit to rasterize the PDL format data as in S36.

The controller 100 then stores the raster data in the print queue. At this time, if the print job data includes parameters used during printing, the parameters are also stored in association with the raster data. Furthermore, if parameters are associated with the raster data, printing is performed using the parameters.

Next, the controller 100 determines by the engine control unit that raster data is stored in the print queue, the rotational speed of the heating roller 61 reaches a predetermined rotational speed, and the temperature of the fixing device 6 exceeds a predetermined temperature. If it is determined that this is the case, sheet feeding is started. Then, the print engine 4 prints the raster data on the sheet. At this time, the fixing device 6 fixes the toner image on the sheet.

After S23, the controller 100 determines whether printing is completed (S24), and if printing is completed (S24: YES), the flow of FIG. 3 ends.

According to the printing apparatus 1 of the present embodiment described above, the controller 100 receives the preceding command (S11: YES) and determines that the print job data being received is not to be subjected to either secure printing or storage printing. If (S14: NO), print preparation processing (S19) is executed before receiving the print job data. Thereby, FPOT can be shortened.

On the other hand, if the controller 100 determines that the print job data being received is to be subjected to secure printing or storage printing (S13: YES) or (S14: YES), it does not execute the print preparation process (S19). This prevents unnecessary continuation of preparatory operations before printing, and improves user comfort.

Further, the controller 100 starts receiving print job data (S15), and if it is determined that the print job data being received is to be subjected to secure printing or storage printing (S16: YES) or (S17: YES), secure printing is performed. If it is determined that the print job data is not to be subjected to printing or storage printing (S17: NO), reception of the print job data is started in the second power saving power state, and the received print job data is stored in the RAM 104 (S17: NO). S37). Thereby, when performing secure printing or storage printing, it is possible to enter a power saving state until a user operation is received, and it is possible to achieve energy saving.

Further, since the controller 100 starts the determination process (S16, S17) upon receiving the print job data (S15), the print job data being received includes information indicating secure printing or stored printing. (S16: YES) or (S17: YES), it can be immediately determined that the print job data being received is to be subjected to memory printing.

Further, since the controller 100 starts the determination process (S16, S17) upon receiving the print job data (S15), if the secure print on information or stored print on information is stored in the NVRAM 103 ( S16: YES) or (S17: YES), it can be immediately determined that the print job data being received is to be subject to secure printing or storage printing.

Further, when the controller 100 starts receiving print job data in the second power state (S15), and determines that the print job data being received is to be subjected to secure printing or storage printing (S16: YES), or (S17: YES), the print preparation process (S19) is not started, the storage process (S18) is executed in the second power state, and the print job data is received. As a result, print job data can be received in a power-saving state in which there is no power consumption associated with the preparation operation, so energy savings can be achieved.

Further, in the second power state, the controller 100 executes determination processing (S13, S14) upon receiving the preceding command (S11: YES), and determines whether the print job data is subject to secure printing or storage printing. If it is determined that this is the case (S13: YES) or (S14: YES), the print preparation process (S19) is not started, the storage process (S18) is executed while the second power state is maintained, and the print job data is received. do. As a result, print job data can be received in a power-saving state in which the operation panel 110 is turned off and no power is consumed due to preparation operations, so that energy can be saved.

Further, in the second power state, if the controller 100 determines that the print job data being received is to be subjected to secure printing or stored printing (S16: YES) or (S17: YES), the controller 100 controls the power saving of the operation panel 110. The print job data is received while remaining in the second power state without canceling the state. As a result, print job data can be received in a power-saving state in which the operation panel 110 is turned off, resulting in energy savings.

Further, in the second power state, upon receiving the preceding command (S11: YES), the controller 100 starts determination processing (S13, S14), and determines whether the print job data is subject to secure printing or storage printing. If it is determined that (S13: YES) or (S14: YES), the power saving state of the operation panel 110 is not canceled and the print job data is received while the second power state is maintained. This allows the operation panel 110 to receive print job data in a power-saving state, resulting in energy savings.
