Careful with the Canon inkjet printers, they don't all use archival inks. For events, your best bet is a small portable dye-sub printer. Canon, Kodak, Olympus and others make some nice dye-subs. You could give out business cards to costumers that want larger prints. p.s. later this year Zink will be selling their inkless printers. check them out at www.zink.com

Question the question. Answer the question. Question the answer...
