TechRepublic member e30ric
was having a serious printing problem, and so he posed the following question
in the Technical Q&A:
“After installing Windows XP Service Pack 2, I tried to use my printer and
started getting an error message the gist of which was ‘Spooler Subsystem App
error.’ I can turn on the Print Spooler in the Services section of
Administrative Tools, but that doesn’t make any difference. I’ve tried to
uninstall the printer driver to reinstall an XP upgrade, but the uninstall
fails also. My printer is no longer listed in the Device Manager and I can find
no help for this problem in the ‘Help and Support’ section. I tried to do a
repair using my original Windows XP Home Edition CD, but got a notification
that since I’ve installed SP2 I can no longer use this disc for anything until
I uninstall SP2. Is there any way to repair the ‘Spooler Subsystem App,’ or reinstall
it, or am I going to have to reinstall XP and all the applications I use on a
regular basis? The printer is an older Xerox (Workcentre XK35c), if that
matters, and I have become quite comfortable using it. Please help!”

responded, “It’s the Windows Firewall causing the issue. Try these steps
to resolve that issue:

  1. Click
    Start, point to All Programs, then Accessories, then Communications then
    Network Connections (or you can right click My Network Places on the
    desktop and choose Properties)
  2. Right-click
    the Local Area Network or the connection you are using, then click
  3. Click
    the Advanced tab, and then click Settings
  4. Click
    the Exceptions tab
  5. Click
    the File and Printer Sharing checkbox
  6. Click
    OK (twice)

Also, when you use the netsh command, it can provide the
same result as when you go into the Windows Firewall, clicking the Exception
tab, and enabling file and printer sharing. To use the netsh command, click
Start, point to All Programs, point to Accessories, then click Command Prompt.
At the command prompt, type the following line:

netsh firewall set
service type = FILEANDPRINT mode = ENABLE

Press Enter.”
