Are you *sure*? :-)

Sounds to me like you're having DTR and/or XON/XOFF problems.  You say the
buffer isn' full, you you also state that it happens when you try and print
a page.  Am I to assume the problems happen when the second line is
printed?  Remember, it takes a lot of time to move the print head around,
and some printers are notorious for lossing info when a CR is being
executed.  This happens with older printers, I know.  Sometimes they hold
DTR high (or is it low? I think low) while they execute it, so that you
don't send info to it then.  Or, they send and XOFF to stop sending.  In
anycase, Have you set the switched on the printer to every conceivable
setting?  Sometimes this works.

In MicroSoft Word, there is a dumb serial driver.  I also happen to have a
small Rascal program (anyone who knows what *that* is gets a cookie!) that
you might like, though it's rather crude.  I might be able to get the source
for it as well. . .
