After I read through the other reviews, I was excited about the device and have it ordered me. Unfortunately, I was under the assumption that you can also print on envelopes so that you it in the normal paper tray lays down. However, it turned out that this is not intended. One is forced to insert the envelopes in the separate compartment which only one (!) Summarizes envelope. Nevertheless Taking the envelopes into the lower cassette, they are often stuck not feed properly and remain. If it works with the collection, all have envelopes on (in my case, DIN C5) wrinkles.
So the unit went back, and I have reappointed me a HP Laserjet (model P1102w). The is much more compact and eats almost everything. In the Envelope Tray are also up to 10 pages. In addition, you can also refuel during printing paper.
WLAN configuration:
Contrary to other reports, I had no problems with the wireless setup. The SSID contains spaces with me, which was no problem. Within 10 minutes it was all set up.
