I have been trying to print large scale tiffs and/or pdf files to our company's oce 9400 printer, and all I get out of it are blank sheets about 36" x 16". My plotter is set up as a Centronics printer/plotter, and it is using the Oce PostScript driver. I've tried to find the answer myself on the internet, but to no avail. Anyone else have a similar problem, or know how to fix it?
