I am new to this area, and have recently purchased a 36" wide format color printer. I am looking to use it for construction bluprints, stickers, banners, magnetics, and other promotional items for my company. Due to the printer being from the late 90's, there are only drivers available for XP and older on the Windows format and OS 8 & 9 in classic format up to 10.4 on the Mac format. In your opinion, which format should I be looking for to run this printer? Also, since I am looking for a used computer, which programs will best suit me to use this printer for its full potential? BTW the printer is a designjet2500cp.
