PDF Printer doesn't print from Windows service

[al.kl]

Hi,

We have a Windows service that is printing documents using PDF Printer. The Windows service is running under non-administrative (and not Local Service) account. As it happens, PDF Printer doesn't store anything in the output folder until we add the Windows service's account to the Administrators group. Documents are displayed in the PDF Printer queue without any problem and all of them are marked as 'Printed'.

Is there any way to see what's going on? What other actions should be taken to allow this Windows service's account to print documents using PDF Printer (obviously, without adding this account to the local administrators group)?

Thanks,
Alex
