They say it is not compatable.I removed a jammed paper, and since then anything I print,such as invoices, checks and such, come out with blotchedprinting and paper tears. I get NO help from technicalsupport(They're learning). No 800 number, which means youhave to call CA on your buck.I used to swear by HP. Now I am convinced that theirproducts are close to junk. My opinion is STAY AWAY!
