Earlier on in the testing, I added the pritner driver (user already administrator and print operator) and I could print from my application with no problems. But after that, with no changes, it stopped working..
It does sound like a user-rights thing but I still haven't been able to figure out what I need to change, or why it stopped working in the first place. Both local and remote printers in windows wouldn't respond to my program but I can print from notepad and can print a windows test page..

>This error message is common whn the client could not contact the remote printer spooler or load the printer driver. In your case it seems to be that it has something to do wirh user-rigths.

>Though you say you made everybody a member of the printoperatorsgroup they still have to log off and logon again to get these settings. Try if you can print from other aplications (e.g. Notepad,Word or excel).
