My wife has a new Compaq Presario F756NR running Vista Home Premium.
She has a Samsung ML-1210 laser printer that worked find under XP.  I
installed the Vista Driver and when the install reached "Do you want
to print a test page?" I answered "yes."  The printer "awoke" and the
data light on the printer began to flash but nothing printed.  

I tried to print a Word document, the data light on the printer
flashed, and when I opened the printer window I could see that it had
received 64KB of nnnKB, then 128KB.  But after that there was no
further movement until I got an error with no explanation.  

After I flushed the print queue, and turned the printer off/on, I
created a very small text file with Notepad.  This printed
successfully.  But when I tried to print another Word document, I
experienced the same failure as previously.

Can anyone offer an explanation, or a clue?

Thanks very much.
