Glacial Printing from Mac Shared Printer

Hi --

I can connect to my HP LaserJet 1320 all right; it's a shared printer from
my PowerMac G5 model, running Tiger (10.4.8). However, the printing process
is incredibly slow -- even a single page is glacial, and multiple pages are
pretty much out of the question.

Is there something awry with Vista and printing to Samba-shared printers? Or
does anyone have any tips for setting up the share so that it still works
properly with a predominantly Mac network, but this one lone Vista machine
can actually print to it without such a slowdown?

Thanks in advance--
