Thanks Ingo,
StatusCommand 200 seems to work if the print job succeeds.
Do you know what would happen if the job fails after PrintDocument() function exits?

Regarding the reason, our server does additional processing on print job at the end of the printing, we need to wait till printing is complete. Ideally, we would listen to some signal from the library, but as far as I understood no signals are available. I'll add polling loop for now, but I'm not sure how it would affect the performance. It should be more efficient using some signal or callback.
I think the common scenario is notifying user when printing is complete.

Thanks again,
Natalia.

Hi Natalia,

the function RequestPrinterStatus is a bit experimental.
In the description you can read that there's no guarantee that it works with all printer and all printer driver:
http://www.debenu.com/docs/pdf_library_reference/RequestPrinterStatus.php
Before printing you should use RequestPrinterStatus with StatusCommand 101.
Then you should use PrintDocument.
Then you should use RequestPrinterStatus with StatusCommand 200 in a loop.
If there's no returning value 1 then the print job should be finished or your printer doesn't like this function ;-)

Cheers and welcome here,
Ingo

BTW: What could be the sense to know (and stop the program) if a printout is finished?  ;-)

Hello,

We noticed that PrintDocument() method returns before print operation is complete, and are looking for the correct way to wait for print to finish.
RequestPrinterStatus(300) returns 8208 during print, and 0 when after print succeeds.
Where could we find the description of possible values returned by RequestPrinterStatus?
What is 8208 and what values would be returned if error occurs?

Thanks,
Natalia.
