A trip to Pulsar Pro web site solved that problem by sending me to a site
where I downloaded a program called LJConfig. Now I can set resolution,
and dpi without software. The HP site solved the driver problem for my latest pinter a HP Laser Jet P2015dn. This is a good solution rather than buying new. It needs LJConfig thou to work. It prints real good on orient A4 size toner transfer paper.
