I am looking to possibly purchases a large format printer. I have a few customers who are sending this work elsewere and have offered to send it my way as I do alot of other work for them now. My question is: I have seen several in auctions and am courious as to what the major cost for repairs are if required. I realize the inks are a consumable but what other things should I be looking for before buying a used one. Any specific brands whould be helpful to know about. Seems like most of the ones I find are HP, Thank for any advise you can share.
