maybe it’ll save someone a bit of time.
problem: there is group of people running windows xp and using over the network two canon printers IR c2550 and ur c4850. they dont use central windows printer spooler – they send print jobs directly to the printer. suddenly one user reports that she cannot print from one specific [our…] application.
this program is slightly ‘different’ than most windows applications – pure .net/wpf based app. i dont know if it’s relevant or not; anyway – that user can print from word, notepad etc, but any attempt to print from ‘our’ application ends up with error dialog:
Could not verify the ID and password specified in Job Accounting. Printing will be canceled. Make sure that your computer is connected to the device correctly or the device is turned on
while other users running same up, under similar xp dont have that problem.
solution – everyone was using ancient drivers 2.2 from 2007 ; downloading and installing new urf II drivers [ UFRII_v2.70_Setup.exe from here ] in version 2.70 from 2010 solved the problem.
