Our New DesignJet Plotter prints Purple instead of Blue and Greenish-Yellow instead of Yellow (Using the standard ACAD Blue and Yellow colors) I`ve tried seting the HP Driver to use Manual color option to use "No Color Correction" (This was suggested on HP`s forum) But no help. I`ve been waiting for 3 weeks for an answer on the forum....I thought someone here has run into this and has found a fix. Specs: HP Designjet500 (Latest drivers from HP Site)(Still using original Ink cartridges) with HPGL-2 Card - 160 megs added. AutoCad-lt 2004(Latest sp1) Windows XP Pro 256k mem (Using USB cable) Thanks for any info on this or suggestions to try.... Ron....
