无法打开Windows GDI打印机驱动程序

Question

I have virtual printer installed which prints through redirected port and sends document to real printer via gsview\\gsprint.exe. It works normally when I use gsprint from a normal C++ application. But if call the same thing through a windows service (run as SYSTEM), it gives following error. It sees the printer but perhaps doesn't have access to it. I am on windows 10 but windows 7 also has the same issue. How can I solve this problem?

2006-02-24 gsprint 1.9 Couldn't open Windows GDI printer driver Requested printer: "SupplyDep"

Available printers: "Send to OneNote 2010" "VirtualPrinter" "SupplyDep" "Microsoft XPS Document Writer" "Fax"

Answer 1

I ran into a similar issue trying to run gsprint as the NT Authority/system user. The last post in this link helped a lot. Basically I setup the printer under my user and then I copied the registry entries for the printer to the default user.

Below are the registry keys I copied from HKEY_CURRENT_USER to HKEY_USERS\.DEFAULT

    HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Devices
    HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\PrinterPorts
    HKEY_CURRENT_USER\Printers

You'll need to restart the Print Spooler service (or just restart the server) in order for the changes to take effect.
