I replaced an EPSON about 6 months ago that worked for about 9 months before the paperfeed went out. I thought I was "movin' up" by purchasing an HP, well, this one stopped working after 6 months: the printer carriage gets hung up on the right. I went to the website for troubleshooting options, none of which solved the problem....and the warranty is the biggest weakness...90-days! This alone speaks poorly of the expectations HP has of its own products. EPSON's warranty was 1 YEAR, but I had misplaced the receipt. SO, perhaps EPSON is a better deal, as long as you KEEP THE RECEIPT!

Negative
