Can no longer print from Fedora 29 on HP M452NW

I never had any difficulties installing the HP LaserJet M452NW drivers on my Fedora Linux computers and printing. I upgraded to F29 and could continue to print. Today, my printer stopped responding to any commands form my Fedora laptop or desktop. I can still print from Windows 10. I deleted printer and reinstalled it. I deleted HPLIP and tried to reinstall it. The process has been very slow and I got a server error internal error cups. I used the HP-Setup and HP-GUi withou t success. A couple of times, the printer was installed correctly. But when I tried to print, it started to work. But then it hung on "processing." Other times I got a communications error. Is there a fix?
