networked printer problem..

I have a WinME pc configured as ICS host networked to an XP pc. Internet
sharing and file sharing work great. I have a Lexmark printer on the XP
that I wish to share and access from the WinME. The setup for sharing the
printer on the XP went well and striaghtforward. The setup to enable the
network printer from the WinME pc seemed to go well too. However, I can't
seem to print to it from the WinME. The pc goes through the motions as if
it were sending to the queue.. and then simply closes.. and nothing prints.

I used to have this arrangement working just fine. What do I need to do or
check?
