we have made good experiences with inkjet transparencies (for overhead
projectors) and an off-the-shelf HP photo inkjet printer.
Make sure that you print only with the black ink and be careful that the
ink is dry before removing the transparency sheet from the printer.
When using it for lithography also ensure that the side with the ink is
directly pressed onto the photosensitive coating.

We also tried the same with laser printers, but had the problem that the
toner film on the transparency was not thick enough causing UV light to
pass through which negatively affected the photosensitive coating.

The third thing we tried was a commercial (very large) Agfa Advantage
laser fotosetter (http://en.wikipedia.org/wiki/Computer_to_plate) that
also outputs films.
The films it produced had by far the highest quality, but if you don't
happen to have one of these huge machines nearby they are out of the
question.
