Next, the browsing process and the correction process of the print management information data in the present embodiment will be described with reference to FIGS.

First, the browsing process of the print management information data is as follows.
The process is started by activating a WWW browser in the computer 60 (FIG. 2: step S1).

Next, it is assumed that the URL name or the IP address of the printer is entered in the URL entry field of the WWW browser (FIG. 2: step S2; YES). In this embodiment, it is assumed that the user has recognized each IP address of each printer. For example, in the present embodiment, the IP address of the printer body 10 is set to “133.151.120.92”. Enter this I in the URL entry field of the WWW browser.
By inputting the P address “133.151.120.92” and pressing a return key of a keyboard (not shown) connected to the computer main body 56, the computer 60
The following read command is generated and transmitted to the transceiver 2 of the NIC 1 via the network W (FIG. 2: step S3).

“GET / 133.151.120.92 / HTTP / 1.0” Here, “GET” is a command for reading data, and predetermined information is transmitted to the transmission destination of the command. Request to send back to the sender.

The IP address "133.151.120.92" specifies the transmission destination of the command. When a URL name is entered in the URL input field, the URL name is described.

Generally, the URL is information indicating a management target called a resource. In this example, the URL specifies the predetermined information to be requested. At the time of normal command transmission, names indicating various resources are described in the URL portion. However, when a command is transmitted for the first time to a desired printer by designating an IP address, it is unclear what resources exist in the printer, and therefore, only the IP address is described. A command is sent.

"HTTP / 1.0" is HTTP version information.

Next, the request received by NIC1 is:
The request is transferred to the printer main body 10 via the bus 4 and the connection line 9 by the LAN controller 3.

Next, when the command is input to the printer main body 10, the CPU 11 determines whether the command includes an IP address designating the printer main body 10 (step S20 in FIG. 3). If the IP address is included (step S20; OK), the command is acquired via the bus 14, and then the command is processed using the printer CGI 12a stored in the ROM 12. The command includes the above-mentioned “GET”
Since there are multiple types such as "POST",
First, the CPU 11 determines that the acquired command is “GE
T ”or not (step S21).
If it is "ET" (step S21; YES), the resource name requested by the "GET" command is read (step S22), and the data corresponding to the resource name is read from the HDD 18, or as necessary. Create HTML format data (step S2
3). The data read out here is print management information data, and includes data on the spool file name, sender, transmission date, deletion date and time, and notification destination. When the resource name is described in the URL as described above, the CPU 11 determines the names of all the spool files spooled in the printer main body 10, the sender of the spool file in the first spooled order, Send date,
Data about the erasure date and the notification destination is created as HTML format data (step S24). And
The CPU 11 returns the processing result data to the NIC 1 via the bus 14 and the connection line 9 (step S2).
5). The NIC 1 that has received the data from the printer main body 10 transfers the request to the computer 60 via the network W as it is.

On the other hand, in the computer 60 that has received the data from the printer body 10 via the NIC 1 and the network W (FIG. 2: step S4; YES), the image or character information corresponding to the received data is displayed on the CRT 54.
Is displayed using the WWW browser (step S
5). FIG. 4 shows a display example. The example of FIG. 4 is a case where a plurality of files are spooled in the printer body 10, and the selection box 92 displays the file names of the plurality of spool files. A scroll button 99 for scrolling the spool file name displayed in the selection field 92 is displayed beside the selection field 92. Also,
The information displayed in the sender column 93, the transmission date column 94, the erasure date and time column 95, and the notification destination column 96 indicate that the spooled file in the printer main body 10 has the first spool file “A.doc”. Information. In this way, the user can view information about the print data spooled in the printer body. In addition,
If the user wants to view information about another spool file, the user clicks the scroll button 99 to select another spool file. For example, "B.do
When "c" is selected, the CPU 50 transmits the following command (FIG. 2: step S13).

"GET / 133.151.120.92 / B.htm
l HTTP / 1.0 ”Upon receiving this, the CPU 11 of the printer body 10 sends the data on the sender, transmission date, deletion date and time, and notification destination for the spool file name“ B.doc ”to the HDD 1.
8 is converted to HTML format data and returned (FIG. 3: steps S20 to S25).

Then, the CPU 50 of the computer 60 receiving this data sets the browsing screen 9 in the same procedure as described above.
0 displays information about the sender, the transmission date, the erasure date, and the notification destination for “B.doc” (step S13). In this way, the user can easily browse information on any spool file.

Next, the process of correcting the print management information data in the present embodiment will be described. In the present embodiment, the print management information data to be browsed and displayed can be easily modified as described above. In the present embodiment, the data that can be modified is limited to data on “erasing date and time” and “notification destination”.

When making corrections, the user uses the keyboard or the like to enter new data in the erasure date / time column 95 and the notification destination column 96 (FIG. 2: step S6; YE).
S). The CPU 50 changes the data on the RAM 52 in response to this operation, and also deletes the
5 and new data are displayed in the notification destination column 96 (step S7). When clearing the display content, the reset button 97 on the browsing screen 90 is clicked with the mouse 53 (step S8; YES). The CPU 50 changes the data on the RAM 52 in response to this operation, and blanks the display of the deletion date and time column 95 and the notification destination column 96 of the browsing screen 90 (step S9). If the data of the erasure date is not set, the automatic erasure processing of the print data in the printer main body 10 is not executed,
When the data of the notification destination is not set, the notification is not performed even when the printing is completed in the printer body 10.

When the correction operation is completed as described above, the update button 98 on the browsing screen 90 is clicked with the mouse 53 (step S10; YES). In response to this operation, the CPU 50 performs a correction operation on the browsing screen 90, reads the changed data in the RAM 52 (step S11), generates an update command as described below, and transmits the update command to the transceiver 2 of the NIC 1 via the network W.
(Step S12).

"POST / 133.151.120.92 / A.ht
ml HTTP / 1.0 ”“ EXPIRE = nn TO=ccc@bbb.co.jp ”Here,“ POST ”is a command, and the destination of the command is updated so that data to be transmitted thereafter is updated. In this example, a request is made to update the deletion date and time data and the communication destination data of the spool file “A.doc”.

"EXPIRE" is a form and "E
XPIRE = nn "indicates that the deletion date and time will be changed nn hours after the transmission date and time. On the browsing screen 90, the data is corrected in the date format as shown in FIG. The CPU 50 automatically calculates a difference between the changed date data and the transmission date data, and calculates data in units of time.

"TO" is also a form, and "TO = ccc @
“bbb.co.jp” indicates that the communication destination is changed to “ccc@bbb.co.jp”.

On the other hand, upon receiving the above command, the CPU 11 of the printer main body 10 determines that the command is “P”.
OST "(FIG. 3: Step S26;
YES), the resource name included in the "POST" command is read, and the contents of the form transmitted following the "POST" command are read (step S2).
7). Then, the deletion date / time data and / or the communication destination data in the spool file corresponding to the read resource name are rewritten on the HDD 18 (step S28).

As described above, according to this embodiment, WW
In addition to browsing the print management information data on the W browser, predetermined data can be rewritten, so that there is no need to re-spool the print data and print management information data, thereby improving work efficiency. be able to.
