M477fdw will not print

[SquirrelChicken]

I've had this printer/scanner yada, yada, yada... hooked up for a few months now.  Initially, it worked great.  Now, intermittently, different computers that used to be able to print from it, cannot.  And now, my main desktop HP computer will not print from it.  I can't print a test page.  When I try, I get this:  "Error printing on N*******3 (HP Color LaserJet MFP M477fdw)  The printer couldn't print Test Page"  I think that the "N***" term is my printer's serial number, so I've not included those details.

first thing would be to check the port settings.  if you have mutliple workstations printing to this i'm assuming its networked and should have a static IP address.  see if that IP has changed to something different.  if in the port configuration you see something like WSD you want to change that to an IP address.  are you running windows 8/10 or something in between? make sure in your PC settings option, under printers, that you uncheck the "let windows manage my printer" box.

The N#$#$^% would indicate that your drivers are set to print to the hostname of your printer. Depending on your network and how well your DNS servers work this might cause drop off. The best way to configure for a network would be, as suggested, configure a static IP address and configure the driver to use a Standard TCP/IP port.
