The Lexmark owner with this problem ( a senior) finally got back to me.
Using remote assistance, I tried the copyfilename
\\XPmachine\printershare command from his Vista laptop (wireless to
Belkin router) (XP machine is wired to the Belkin, Lexmark 8350 AIO set
up on this computer).
When the command is executed from a Vista laptop admin cmd window using
a file saved as a print saved to a file (*.prn), the printer prints a
blank page.

When you create a Local Port using \\XPmachine\printershare you
basically
copy the file to the other machine

Can you print to file on the Vista machine then copy the print file to
\\XPmachine\printershare?

you will need to open a command prompt

copy filename \\XPmachine\printershare
