When printing the printer start flashing paperjam led and does not print. When all work are canceled the printer won't "reset" even if power is switch off. When switchin on again the same yellow led (paper jam) is still flashing and printer won't print.
Using HP Print and Scan Doctor shows that printer is reserved but there are no print que and spooler is empty, and stopping/starting printing service does not help either.
Printer also has a battery but battery status led does not show any battery status, charging indidator works when power supply is connected.
