I tried the printfab thing about a year ago and had no luck with it. My printer is old, I would really like to find a replacement for it, with Postscript. I can't afford $3,000 for a tabloid laser printer, but if there is in fact a true Postscript inkjet printer available, I would love to know about it.
But, please help me understand this: If OSX drivers are actually Raster Image Processors; i.e., if the file gets RIPped by OSX, then why would one even need a Postscript printer? I believe that what a RIP does is to take the vector information in the file and create a bitmap which is then put on paper by the printer. The RIP can reside in the computer or in the printer, but ripping doesn't need to happen in both places. Right?
In fact, I have always wondered about this with OSX, since Postscript type does print sharp and clear, at any size. But this is not so for an EPS graphic; the image is bitmapped at a very low resolution - whatever application I print from.
I can get nice prints from Photoshop (hi-rez bitmapped files) - or at least I could before I started messing with GIMPprint and Gutenprint. That's what ruined my colors. I used to be able (with OSX) to print a file from Photoshop and see colors very close to what I see on my screen. I tried uninstalling Gutenprint, but I could never get back to good color reproduction. I don't remember what problems I had with Printfab; maybe I'll give it another try.
But, once again, does anyone know of a large format Postscript inkjet printer? Two of you have said they do exist, but I have not been able to find one. Any specific info would be appreciated.
