problem stay on every computer Win7 or 8, USB/network. Strange enough, HP Print/scan doctors doesn't find any problem except for a Homegroup-error. Why this error appears each time i don't know, its very strange that it does appear. If you print a testpage from a HP-program, the printer works, if send via windows - printer properties it doesn't.
In my 20 years + as IT Manager have never encountered such problems. HP support don't help. If i contact HP Belgium they say i'm at the wrong address, if we contact HP USA they send me to HP Belgium again. Support is ZERO. Lost client due to this.
