Yes, "what goes in comes out" with regard to frequency.  It takes much
more than a simple transformer to change the frequency.

Many electronic appliances are specifically marked 50/60 Hz on their
nameplate, especially the ones with a 110/220 V switch.

I did read somewhere, probably in a Toshiba printer owner's manual,
that while there product usually did work on 50 Hz, it was not
guaranteed or recommended, that it would likely shorten the printer
life (something ran a little hotter than intended, I believe) and would
void the warrantee.

If you will be frequently going back and forth between north america
and europe, I'd recommend finding a printer which is 110/220 V
switchable and also rated 50/60 Hz, which shouldn't be all that
difficult.  Recently, I've even seen some computing equipment that
AUTOMATICALLY switches between 110 and 220, or possibly it doesn't
really "switch" at all but just has a very tolerant power supply input
range.
