FIG. 2 shows an example of the operation of the printing system that is common to the case where the printing device 2000 supports printing of the encrypted PDF file and the case where the printing device 2000 does not support printing.

As shown in FIG. 2, in the printing system, first, whether or not the inquiry transmission unit 1008 of the mobile terminal 1000 supports printing of the encrypted PDF file to the printing device 2000 (printing support of the encrypted PDF file). (Presence / absence) inquiry is transmitted (step S1000).

The inquiry receiving unit 2001 of the printing apparatus 2000 receives an inquiry from the mobile terminal 1000 (step S1001). In the inquiry receiving unit 2001, it is confirmed whether or not the printing device 2000 supports printing of the encrypted PDF file (whether or not printing of the encrypted PDF file is supported) (step S1002).

When the printing of the encrypted PDF file is supported (step S1002: Y), the response transmission unit 2007 of the printing device 2000 responds by inquiring that the printing of the encrypted PDF file is supported (step S1002: Y). OK) is transmitted to the mobile terminal 1000 (step S1003). The response receiving unit 1009 of the mobile terminal 1000 receives the inquiry result (answer) from the response transmitting unit 2007 of the printing device 2000, and confirms the inquiry result (step S1004). Subsequent processing transitions to the flow of FIG. 3 (step S1005).

When the printing of the encrypted PDF file is not supported (step S1002: N), the response transmission unit 2007 of the printing device 2000 responds by inquiring that the printing of the encrypted PDF file is not supported (step S1002: N). NG) is transmitted to the mobile terminal 1000 (step S1006). The response receiving unit 1009 of the mobile terminal 1000 receives the inquiry result (answer) from the response transmitting unit 2007 of the printing device 2000, and confirms the inquiry result (step S1007). Subsequent processing transitions to the flow of FIG. 4 (step S1008).

FIG. 3 shows an example of the operation of the printing system when the printing apparatus 2000 supports printing of an encrypted PDF file.

When the printing device 2000 supports printing of an encrypted PDF file, in the mobile terminal 1000, the print job generation unit 1001 creates a print job of the encrypted PDF file, and the print job transmission unit 1007 creates a print job generation unit 1001.

In the printing apparatus 2000, it is confirmed whether or not a certain time has elapsed during the printing standby state (step S3006). During the time during the print standby state (step S3006: N), the printing device 2000 confirms whether or not the mobile terminal 1000 that has executed the transmission of the print job is held over the printing device 2000 (step S3007). If it is not held over (step S3007: N), the process returns to the print standby state.

When the mobile terminal 1000 that has executed the print job transmission is held over (step S3007: Y), the printing device 2000 reads the unique information of the mobile terminal 1000 by the mobile terminal authentication unit 2005 (step S3008). Next, in the printing device 2000, the mobile terminal authentication unit 2005 inquires about the unique information in the encrypted PDF file and the unique information of the read mobile terminal 1000, and confirms whether or not they match (step S3009). .. If they do not match (step S3009: N), the process returns to the print standby state.

When the unique information in the encrypted PDF file and the unique information of the read mobile terminal 1000 match (step S3009: Y), the printing apparatus 2000 executes a printing process by the print execution unit 2006 (step S3010). ).

When a certain time has elapsed from the print standby state (step S3006: Y), the printing apparatus 2000 discards the print job (step S3011). Further, in the printing apparatus 2000, after discarding the print job, an error message is created and transmitted to the mobile terminal 1000 (step S3012).
