So I have a really niche weird purpose for wanting an 11x17 printer and my a3 inkjet hasn't been up to the task but marketplace struck again with a3 color laserjet for 40 bucks. Initially having some issues with print quality but after a good cleaning it has improved drastically. I'm having a weird issue, so when I searched for drivers for it on the hp website it gives me a postscript driver and a pl6 driver. The pl6 driver will let me print in color, but doesn't work for my adobe projects. The PS driver will only print grayscale and I've searched the options endlessly for an option to enable color but it only will print in monochrome. How do I get a postscript driver working for this printer?
