Local shop is selling out, and I have oppurtunity to purchase equipment, printer I am especially interested in HP Design Jet Z6100. I only have roland machines here, and I know nothing about HP equipment. The price is $3500. We currently use roland SP 540 with eco solvent inks, We do all types of vehicle lettering, graphics, signs, some wraps, as well as some backlit signs. My question is anyone have any advice or experiences with this printer. I would hate to buy this printer and find out I won't use it because my Roland prints better images. Thanks For any advice
