Printer only prints outline fonts

[r83011]

Following a firmware update to version 20160921, my Color LaserJet Pro M452dn started to behave in a mysterious way. All text that is in the document is printed in an outline font, not in the font that is present in the document. How can I get the printer back to a normal behavior?

I have tried to send documents for printing both from a Linux machine (OpenSuSE 13.2) and from a Windows machine (8.1, 64 bit). The problem was there in either case.

Thank you for posting on HP Forums,

As I Understand the printer only prints outline fonts after the recent firmware update,

I'm afraid the only way to end the mystery is by resetting your printer back to factory defaults.
(Remember this would remove all the web services and personalized settings).

Since resetting the printer is sensitive information, I've sent a private message to you.

Thanks for your hint, but it didn't help. I followed the procedure that you indicated but the printer still behaves in the same incorrect way.

I've been in touch with the HP staff here in Germany. They came up with more ideas.

First, I was told (via telephone) to update the printer drivers. That didn't help.

Then, this was followed up by an email that suggested to start the color calibration via the printer's menu and to repeat the calibration process for 3 or 4 times. I have no idea why, but this procedure solved the problem.

Thank you so much for posting this!! I had the same problem, with the firmware update release this Sept (firmware update 20180201 for my Mac) on my Color LaserJet Pro MFP M477fdw. Everything was printing in outlines of the letters. I ran the on device menu color calibration as you did after after running it just once the problem was solved!!!
