This printer is a beast. Much larger than other printers I have had. Can print 11x17 and 8 1/2x111 from two different paper trays. Easy to setup but there are a lot of settings in the control panel. One nice feature is you can push a button and the output tray goes back in. Them when you print it automatically comes back out. Very nice quality prints that do not run if they get wet with a little water. The scanner works great. By some spare ink, you will need it once you start printing.

Overall this printer is fantastic. We’ve had a few issues with the wireless connection holding and down loading drivers. The print quality is really good for the price, and the overall capability for a small office works perfectly.
This printer is GREAT. All in one that does everything. It was easy to setup, it is easy to print with. The scan feature is great! I recommend using the XL cartridges.
