1. Installation can be hakelig. I myself have made me a bit stupid when assembling. I overlooked the black box that you have to push on the back (the duplex unit). That's why I thought the unit was broken, because the drawn paper completely crumpled back came out of the device. After insertion of the duplex unit, the problem was solved, but the online help has not helped me, I had even draufkommen.
2. WLAN: I have for safety reasons a "hidden wireless router". Since then you have to perform manual configuration on the HP Officejet. That's pretty tedious. Once the HP Officejet but the router found only once, it runs fine. You can access from the PC to the browser at the IP address of the HP Officejet and the unit to be configured extremely comfortable.
3. Linux: Never I have a printer so easy to set up on Linux. If you use the USB port, all functions (print, scan, fax) will automatically recognize my openSUSE 11.3 and I have the one encountered only confirm. When you go wireless, you have to let only search for the device active. This one should be entering the device via Wizzard with "Access Network Printer / TCP Port" with its IP address and then test the connection. Automatic discovery of the device did not work with me, but that may be due to the restrictive settings of my router.
4. Noise: The paper tray with the duplex unit generates such a pity-exciting noise that I hesitate before each printing process, whether I want to do this ordeal the poor device. Maybe I'm just not tough enough in delegating work.
5. To switch off: When the installation has a scrolling text on the display indicates that the printer should be properly turned off with the off switch button and not by simply disconnecting the supply voltage on the power strip. This requirement could be a little tiring, because I would like to turn to a central power strip all equipment, which is of course no longer allowed in the long run.
