Hello! I need a LOT of information, and the folks at Macpro said this was the place to ask. I work for a retail mail-order gift fruit shipper in Florida. We are thinking of buying a laser printer to do our own brochures, coupons, confirmation letters, weekly reminders, and that sort, rather than have outside printing companies do it. We WOULD be using graphics; both scanned or clip-art, and in-house drawings of things. As it stands, we have an AT clone, and we are currently using my personal Mac + for various graphic things. As software goes, we would be purchasing that as well. Now the questions: We would rather use the Mac for the DTP stuff, but would need to have the printer capable of printing things from the AT as well. Are there any (many?) compatibility problems I need to be aware of? Should we purchase a higher horsepower Mac? Is a larger/colour screen necessary? Is Postscript worth the extra cost? A big question is what are the paper handline capabilities of different printers? I mean, can we print letter/legal and odd size things? (Specifically, post-card sized stuff) How much does it cost to operate a printer after it is purchased? Do ALL lasers use toner, or is there a different way of printing? Is colour printing worth the extra money? I've read colour laser printers have just broken the $10k barrier. Is that full colour printing? Whats the quality like? If we were going to design our own colour brochure, coupon, whatever, how would we go about it? Is there software available that would let us do seperations? (Then do we print 4 copies of the document; 1 for each colour, or how does that work?) I realize this is a LOT to ask. If you'd like, I'd be MORE than happy to just give you a call at your convenience and discuss this. I do appreciate any help offered, and thanks in advance. Cheers, Mike
