[X-Newbies] Shared Windows XP Compaq IJ600 printer problems

[MnVikes]

Hello all, I've been a member of the list for about 2 weeks, trying to  
pick up some pointers and now I've (finally) got my own Mac to run OS  
X. The transition to OS X from XP has been both frustrating and  
gratifying. A solution to the main source of my frustrations is the  
purpose of this email.
My printer is directly attached to a WinXP  box which is "workgrouped".  
I've followed the directions found on the following web page to print   
from OS X.

The symptom I'm having using the above instructions is the SAME that I  
have had using the more intuitive method  which the print setup wizard  
uses (a "generic post script printer")  - the printer doesn't print  
anything, HOWEVER the document IS seen by the Windows machine - the  
print queue shows a "downlevel" document for a few seconds and then  
NOTHING - the printer seems to ignore it.  The printer is a Compaq  
IJ600 - which to my understanding was manufactured by Lexmark. If  
anyone has a solution I'd be very grateful.
