Hi All,
I'm creating a windows forms application.
I do printing in it.
I need to know exactly when the printer has finished printing and how.
I tested many codes but found no solution for it.
Could you please help me solve this issue?
Thanks in advance!
Hello,
If .net technologies are being used then a "PrintSystemJobInfo" object contains an "IsCompleted" member that returns a boolean value.
There is also an "EndPrint" event - part of the PrintDocument class that might be useful

Hi Peter,
I do know about that, but my target is detecting when exactly phisical printer completes printing.
EndPrint event has been raised when last printer page is rendered on the printer's graphics.
But it still far away from the printer itself.
Using IsCompleted of PrinterJobInfo I see a print job as completed right away it has been sent from printer spooler to the printer, but printer may be out of paper so it is actually is not completed.
Thank you
Hello,
There's also a "GetJob" API call:

To use it though, you need to have a JobId number that is for your document being printed - it should hopefully return "JOB_STATUS_PRINTED" as part of the JOB_INFO structure when document is finished.

The only absolute way to determine if the printer has finished is to ask it - which I'm afraid is outside of driver / spooler control. You'll need to use an SNMP query to the device.
Hi the_cat,
I wanna know if SNMP is possible for USB printers.
I also need some sample code.
Regards
SNMP is not supported for USB so you would need another method. Maybe look into retrieving the printed status from the printer through PJL as USB is bi-directional? I don't have any sample code but check out this website http://www.undocprint.org/start which has links to not only USB but also the Printer Job Language (the manual for which can be downloaded from HP: http://spp.austin.hp.com/SPP/Public/...cDownload.aspx )
oh, you can use JOB_INFO2
