Hi Petter,
thanks for tipp! It now works. Printer: HP Officejet 7500a driver hp-officejet_7500_e910.ppd 1. start hp-setup 2. connect via usb 3. wait(!) until system has automatically installed printers 4. disconnect usb cable 5. use the Network/Ethernet/Wireless network (direct connection or JetDirect ) 6. give ip-address 7. type wifi-password in Printing and scanning works fine... Other "wireless" option printer works, scanner fails...
