HP Laserjet, Color printing

[AMC258]

Does anyone have a Color LaserJet printer and get it to work?

I broke down and bought a HP Color LaserJet 4500N, and it prints fine from other computers, but from my A3000, the colors are mixed up.  Cyan prints yellow, magenta prints cyan, and yellow prints magenta.  There are some other artifacts but the color problem is what concerns me.
I am using TurboPrint 7.15 and haven't tried any other means yet.
I use the driver HP_ColorLaserJet5.  I can't believe HP would have changed the way colors print from one printer to the next.  Is it possible the driver doesn't work?

I have already tried the PostScript route, but, not all applications support this.  In fact, I can only get IBrowse to work right now.  I may be doing something wrong though.

Sometimes it is advantageous to output to a file so you can modify the output before printing.  This is extremely helpful for use with IBrowse which does not scale it's output to fit the page.
