Emigre's Lo-Res Plus?
The combination of pixellation and soft edges make its character impervious to degradation.

And I guess any "soft" font, like ITC Slimbach.

I�ll take the soft non pixel path, thanks !!

Jean-Fran�ois' Le Monde Courier. This typeface was designed with, among other things, the rigours of low resolution printers and fax machines in mind.

Have a look at PMN Caecilia.

Wans't this the whole point of officina?

Charter, Swift, Lucida, Yes Officina, Stone.

Thanks for all the suggestions, I liked very much Le Mond courier, but I think that maybe Caecilia or Officina and Mendoza or Raleigh are the ones which will fit the project.

I have not very good idea about how each printing method affects the type, I think someone else could be interested in what you guys know.
