Did I damage my XP print spooler

Hi, I have installed a Minolta QMS 2300DL color laser printer on a
system that previously had a Lexmark laser printer. Very often when I
try to print a document, I get an error message instead of a printed
document:

Spooler SubSystem App has encountered a problem and needs to close.
We are sorry for the inconvenience.

Other times, the printer prints OK. I am aware that there are some
well known conflicts between Lexmark drivers and other manufacturers'
drivers. I used the sc config command:

sc config spooler depend= RPCSS

and the printer seems to be working OK right now, but I don't know if
I solved the problem.

I have one question:

1) When I first tried making the print spooler service dependent only
on the Remote Procedure Call (RPC) service (RPCSS), I mistyped the
command, ommitting the space between = RPCSS: sc config spooler
depend=RPCSS. Did I introduce a new problem by doing this?

Thanks,
