After my adventure with the printer Kyocera FS-C5250dn took no happy end, I opted for the alternative in the form of the printer HP LaserJet Pro 400 M451dw. The printer is easy to operate, has a clean printed image and the drivers do their job. Nice, I find that the toner level is displayed on the display of the printer by default and without long menu sequence the printer's IP address. The printer hums quietly (unobtrusive) for a few minutes after switching on or after the automatic calibration (volume comparable HDD / notebook). At rest in the ON state of the printer is not booming. The noise during printing is also not too loud. When HP-foreign Accessories storage expansion Kingston KTH-LJ2015 / 256 PC2-4200 memory is detected 256 MB easily.
