May I ask what brand(s) of printer had the problems? My DH had a lot of problems with Epson printers recently. He also tried an HP Office Jet, that was mostly DOA. He liked the 2-sided printing on the HP, so he hated returning it (I read a lot of bad things about that machine after he purchased it).
I need a new printer as the one I currently have is very old and has few options on it. I'm finding difficulties with drivers for a non-Windows OS. I have not options what-so-ever -- not even whether I want to print in draft mode. Since ink is the major printer cost, I figure that it is more cost effective to purchase a new printer than to stay with the old one.
Regarding using a copy shop, I live far from a copy center, so I would have to factor in fuel/car costs as well as travel time (1.5 hours just for the round trip). It can be inconvenient to be in the middle of a project and unable to continue because I messed up my last PP printout (and I don't like having to draw them by hand!). I generally print my designs via software or PDF files, so accuracy is not an issue.
I've worked on quite a few projects on which I had to tape sheets of paper together, so I am certain that a wide printer would be useful for other activities in the future.
