HP LaserJet Pro M426fdn settings and factory reset
hardware
When running my HP LaserJet Pro M426fdn for the first time I didn’t removed touchscreen foil and my finger slipped over when selecting location of my printer. I ended up with having proper language but location set to Estonia and some reports (like Google Cloud Print configuration leaflet) printed in cyrylic.
Unfortunately, due to extreme stupidity of HP engineers you can only change language of your printer using standard configuration menu. But, in order to change location of the printer you have to perform a full factory reset of your hardware.
And here my problems started, because none of the solution I found seemed working on my printer.
There are various descriptions of solutions and way how you can reset settings of HP LaserJet Pro M426fdn printer or how to bring it back to factory defaults. Often denying each other. Finally, after calling HP support twice and digging up through Internet I managed to discover the proper solution.

Settings reset
Turn the product off.
Turn the product on.
When HP logo appears, press and hold the lower right corner of the touchscreen. Keep it pressed for approx. 45-60 s.
When the Permanent Storage Init. message appears on the display, release the press.
When the product has finished initialization, it returns to the ready state.
Works as written in last point. Resets all settings, but ends up in ready state, not in language and location selection welcome screen. Thus, does not reset the printer to factory defaults state.

Not working solutions
Press buttons on the left side of touch screen: up (back), down (help), up (back), up (back). This supposed to display factory menu from which I was supposed to be able to select full factory reset.
Does not work at all on HP LaserJet Pro M426fdn.
