We have a new printer in the office, a Toshiba Studio 3511 colour laser. It has 3 drivers, postscript, colour and black/white. I've been having some trouble printing. I get and Acad error "test failed" when using these drivers under different circumstances. I am thinking that the ctb's that I use to plot are conflicting with the driver (ie. if my ctb wants to print some pens in colour and I choose the B/W driver). This train of thought seems to work most of the time, but at times, with certain drawings, I can't print with colour at all. This is a problem. Anyone have any ideas? Caddie Hilton
