HP Recommended
HP LaserJet Pro MFP M426fdw
Microsoft Windows 10 (64-bit)

The updated driver for my printer will not install (HP M426fdw).  Disconnected my printer.  Removed my old driver (8.001329.6488), restarted the computer, installed the new driver (16.0.22049.103), restarted again.  Clicked on properties for the printer and it still says the old driver.  

 

The reason I am trying to update the driver is because my printer stopped printing #6 envelopes.  It will print #10 but not #6.  In fact, when you do a drop down for the envelope sizes a #6 envelope is no longer a choice.
