The HP Officejet 5510 is an all-in-one (AIO) copy, scanning, fax, and printer. 4 in 1 compact machine. This is a really really good machine the fact that is compact. If you need space and you have no room for it buy this machine. The HP OJ is MUCH MUCH BETTER then the one I reviewed for the Lexmark X6170 (see my review for that machine). I had made NO Return or Exchanges for the HP. HP CHECKS their quality of printers before they give to consumers THANK GOD. Well ALL HP printer's will discontinue 1 yrs from the date its first introduced it. It was introduced October 2003 and now it's September 2004 so it will be discountinued. I hope HP keeps on making EXCELLENT QUAILTY PRINTER's weather is inkjet or Laserjet. GOOD WORK HP :)
