this might sound like a newbie question (it actually is). I've seen many printers that are usually used for creating proofs on ebay sold together with a PC and some software like EFI Colorproof. Do you need this software to be able to print on those printers? Are there no printer drivers provided?
I've always been creating my PDFs sending them to my print shop blissfully ignorant of what goes on once they receive my files. I I figured I could get a used Epson Stylus Pro and have my proofs right in-house. But there is more to it than I expected (isn't there always more to something than you thought?)
Could somebody elaborate a bit how it all works?
