    Good General Purpose Printer

    Bought two of these for a warehouse application; they print 2000 shipping documents (each) weekly without complaint in a warehouse / dock environment. Network connectivity and config with no issues for anyone with any experience with setting up printers.

    I NEVER write reviews or online posts about anything but I HAD to about this printer. I can't even tell you how much I LOVE it! Even with the cartridges that came with it, I could do tons and tons of printing and I certainly wasn't expecting that! I run a quilt shop so needed the color for printing out patterns and customers are constantly amazed with the quality color that my patterns have. The paper almost has a bit of a sheen on it when it comes out. This printer is very professional and super quality. The absolute best printer I have ever had with the best quality color! Our computer specialist recommended another brand which I purchased; poor printing and I had to replace cartridges way more often. I had suggested HP products to him and he said that the "other brand" was just as good and I would get professional looking patterns using it! I am staying with HP from now on! By the way, I also LOVE me HP computers and every time we have purchased another brand we have trouble with all kinds of little things! Thank-you for this HP printer! Keep up the good work.

    Not for double sided printing

    Works well for single sided but hadn't realised you need to take sheets out and put them back in for double sided. Would not order again as now printing everything single sided hence using more paper.
