  • 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.

  • Love it every bit as much as my old HP.

    I am particularly happy with the two-sided printing which I expect to be using frequently. I never had that before and it is amazingly fast. The extra cost for that feature will be more than made up in the savings on paper and the speed with which it produces the finished product.

  • Excellent Color Laser

    This product replaced the same model which had heavy use but finally gave out. The old model was about 6 years old. One complaint for the new model is when I put the HP 305A black ink cartridge from the old model into the new one, it would not authenticate. All the other colors from the old were put into the new and they authenticated. Second complaint is the new model is taking a long time to print once I click on print from my computer. It also stops during printing as if it's spooling again. This didn't happen with the old model until I stopped working.

  • A good value color Laserjet

    I purchased a M451nw color Laserjet as a beefier substitute for my CP1525nw, which is still running but a bit finicky when it comes to printing on heavier stock. My installation in a wireless configuration went smoothly but took about 20 minutes, so be patient. I recommend the installation method of temporarily connecting the printer to the computer with a USB cable (supplied) to transfer the wireless settings to the printer, but don't connect the cable to the computer until the software installer tells you to. I found the initial color quality to be very good. The toner cartridges for the M451 are more expensive than those for the 1525nw but are rated at significantly higher number of copies. The M451 is taller than the 1525nw but the footprint is only slightly deeper, so I was still able to fit it on my small two-drawer rolling table. I'm planning to buy more memory to max out the RAM, which is easily accessible via a panel on the right side. So far, I'm pleased with this machine.
