printer spooler stops unexpectedly

Printer does not show up in devices and error message says "Print spooler
service is not available." Event log shows this warning right about the time
we started to have problems:

Printer Driver Microsoft XPS Document Writer for Windows NT x86 Version-3
was added or updated. Files:- mxdwdrv.dll, unidrvui.dll, mxdwdui.gpd,
unidrv.hlp, mxdwdui.dll, mxdwdui.ini, stddtype.gdl, stdnames.gpd,
stdschem.gdl, stdschmx.gdl, unidrv.dll, unires.dll, XpsSvcs.dll.

Then a warning the next day:
Printer WebEx Document Loader was deleted.

Then started to get errors:
DCOM got error "The service did not respond to the start or control request
in a timely fashion. " attempting to start the service lxcf_device with
arguments "" in order to run the server:
{323CE21C-A448-40AA-BA74-7FCF1E44106F}

Further events in the log show when we tried to restart the service, show
that the printer spooler service would start and then unexpectedly quit a
minute or so later.

This is a Lexmark printer, also installed a Linksys wireless router at about
the same time. Was this a coincidence that we started to have problems with
the spooler after installing the router? Already tried a system restore and
Windows says nothing was changed. Any way to solve this without reinstalling
Windows?

thanks for your help!
