After install of PDFCreator 1.6.2, LAN Attached Printers stopped working on Windows 7

Hello,
I am running Windows 7, and had installed several LAN Attached Printers, which were workign fine.
I then installed PDFCreator 1.6.2 (Along with PDF Architect), and then I was unable to print to any of the LAN Printers.
The
printers are still showing up as installed, and I can select them to
'print' to.  I do not receive any error message when I print, but the
output is not showing up on the printer either. 
A co-worked of mine has the same problem.
I have un-installed PDFCreator / PDF Architect), but the LAN Printers are still not working.
I then re-installed JUST PDFCreator, but alas, the LAN Printers are still not working.
I have searched for similar reported problems, but have not been able to find an answer.
Printing
to PDFCreator DOES work, and I can generate PDF's of the files I want,
but I really need to be able to print to the LAN Printers as well.
At this point, I am willing to forgo PDFCreator, to get the LAN Printers back to working state, but that isn't working either. 
Can you tell me what all PDFCreator updates (maybe in the Registry) that I could remove, once I un-install PDFCreator ??
or tell me what might be the problem that PDFCreator introducred into my system, where the LAN Printers are not working ?

Thanks
