On Stanley is the Stanley Cybercafe near St. Catherine, and there are Battle Net Cafes on Parc near Sherbrooke and on Du Fort near Hotel Du Fort. The Stanley Cybercafe is owned by a Turkish family that also operates a travel agency there.
I don't believe the Battlenets or the Stanley Cafe have printers or copiers. However, various hotels have business centers where printing can be accomplished. I am not sure what the equivalent of Kinko's would be in Montreal.
