If it is determined in step S401 that there is no print job in the job receiving area of the hard disk 9, the flow advances to step S407 to determine whether there is a print job in the job save area of the hard disk 9. If there is no print job in the job save area, the process returns to step S401. If there is a print job in the job save area of the hard disk 9, the process advances to step S408 to determine whether or not the sheet information used for comparison with the sheet conditions of the print job has been updated. If not, the process returns to step S401.

If the sheet information used for comparison with the sheet condition of the waiting job has been updated, step S
The process proceeds to step 402, where the paper conditions relating to the paper used for the print job are acquired from the saved print job, and at step S 403, the acquired paper conditions are compared with the paper information held in the RAM 3 to determine It is determined whether or not the sheet information held in satisfies the obtained sheet condition. Then, in the same manner as described above, either the execution of the print job or the saving is performed according to the determination result.

As described above, in the present embodiment, the paper condition acquired from the print job is compared with the current paper information, and according to the comparison result, whether the print job is an unexecutable job is determined. If it is determined that this print job is an unexecutable job, the print job moves from the job reception area of the hard disk 9 to the job save area as a save job, Can prevent a subsequent print job from waiting for a long time beforehand.

In the present embodiment, the print job receiving area and the save area are provided on the hard disk 9, but instead, the RAM 3 may be provided with the print job receive area and the save area. Is also possible.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 5 is a flowchart illustrating a procedure of a printing operation of the printing apparatus according to the second embodiment of the present invention. Here, the present embodiment has the same configuration as the above-described first embodiment, and a description of the configuration will be omitted.

The present embodiment differs from the first embodiment in that, when the current sheet information does not satisfy the sheet conditions obtained from the print job, the sheet size is changed (exchange of the sheet cassette, sheet exchange). ), A warning message for prompting the user to replenish the paper is transmitted to the external device 13 and displayed on the operation panel 1501. If the paper information is not updated for a predetermined period after the transmission or the display, the print job is regarded as a waiting job. The difference is that the job is moved from the job receiving area of the hard disk 9 to the job saving area.

More specifically, as shown in FIG. 5, first, in step S501, it is determined whether or not the print job received from the external device 13 is in the job receiving area of the hard disk 9. If there is a print job, the process advances to step S502 to acquire, from the print job, paper conditions relating to paper used in the print job. Here, as described above, the paper size requested by the print job and the number of sheets (number of pages) are acquired. In the following step S503, it is determined whether or not the sheet information stored in the RAM 3 satisfies the obtained sheet condition by comparing the obtained sheet condition with the sheet information stored in the RAM3. Here, the size of the paper fed from the paper feed cassette 1508 and its remaining number are compared with the paper size requested by the print job and its number (number of pages), and the paper fed from the paper feed cassette 1508 is compared. It is determined whether or not the size and the remaining number of sheets satisfy the sheet size and the number of sheets (number of pages) requested by the print job.

If the sheet information held in the RAM 3 satisfies the acquired sheet conditions, the process proceeds to step S509,
A print job is executed, and print processing for the print job is performed. Then, the process returns to step S501, and the presence or absence of the next print job is confirmed.

On the other hand, if the sheet information held in the RAM 3 does not satisfy the obtained sheet condition, the process advances to step S504 to change the sheet size (exchanging the sheet cassette, changing the sheet), replenish the sheet, and the like. A status message indicating warning information for prompting the user is transmitted to the external device 13, displayed on the operation panel 1501, and a timer is started. In a succeeding step S505, it is determined whether or not the sheet information held in the RAM 3 has been updated. If the sheet information held in the RAM 3 has not been updated, the process proceeds to step S506, and the time counted by the timer elapses a predetermined time. It is determined whether or not it has been performed.
The setting of the predetermined time can be set on the operation panel 1501, and the set predetermined time is stored in the NVRAM4. If the time measured by the timer has not elapsed the predetermined time, the process returns to step S505. When the paper information is updated within the predetermined time, it is determined that the user has changed the paper size or replenished the paper, the process returns to step S503, and the paper information held in the RAM 3 is obtained again. It is determined whether the condition is satisfied.

If the predetermined time has elapsed without updating the paper information, the print job is determined to be a print job with an error, that is, an unexecutable print job, and the flow advances to step S507 to save the print job. Do. That is, this print job is moved from the job reception area of the hard disk 9 to the job save area as a save job. Then, the process proceeds to step S508, where a status message indicating the evacuation of the print job is transmitted to the external device 13 and displayed on the operation panel 1501. This status message includes information that can identify the saved print job, such as the saved job name and the user name. When a plurality of print jobs are saved, a column of information on all the saved jobs is displayed. Then, the process returns to step S501.

If it is determined in step S501 that there is no print job in the job receiving area of the hard disk 9, the flow advances to step S510 to determine whether there is a print job in the job save area of the hard disk 9. If there is no print job in the job save area, the process returns to step S501. If there is a print job in the job save area of the hard disk 9, the process advances to step S511 to determine whether or not the sheet information used for comparison with the sheet conditions of the print job has been updated. If not, the process returns to step S501.

If the sheet information used for comparison with the sheet condition of the waiting job has been updated, step S
The flow advances to step S502 to acquire the paper conditions relating to the paper used for this print job from the saved print job. In the next step S503, the acquired paper conditions are compared with the paper information held in the RAM 3 to determine It is determined whether or not the sheet information held in satisfies the obtained sheet condition. Then, in the same manner as described above, either the execution of the print job or the saving is performed according to the determination result.

As described above, in the present embodiment, when the current paper information does not satisfy the paper conditions acquired from the print job, the paper size is changed (exchange of the paper feed cassette,
A warning message for prompting the user to replace the paper or replenish the paper is displayed on the operation panel 1501 and transmitted to the external device 13. If the paper information is not updated for a predetermined period after this display or transmission, the print job is regarded as a save job. Since the job is moved from the job receiving area of the hard disk 9 to the job evacuating area, the user can be prompted to change the paper size (replace the paper cassette, replace the paper), replenish the paper, etc. before evacuating the print job. The print job can be made executable by changing the paper feeder (exchanging the paper feed cassette or replacing the paper), replenishing the paper, or the like.
