I'm needing a new laser printer for my home office. I print tons of In Design documents weekly for school, and I'm wondering if I should consider a PostScript printer? As of now, I'm printing on a LaserJet 1012 that takes forever to print In Design documents. Would a PostScript-compatible printer, speed that process up? I understand PostScript is a printer language, but what does it do for the end user? What's the difference between PostScript Level 2 and 3? Many LaserJet printers support PostScript emulation, is this just as good as natively supporting PostScript? Thanks in advance.
