I appreciate any help here.
iMac desktop was upgraded to Yosemite and now the HP Laserjet CP3525dn printer gets the following error:
"Backend" error, failed to print
Please see the attached error message.
What I have done:
checked printer driver- it is the latest
Reset the printing system on the Mac which appeared to have taken care of the problem but it reoccurred within a few hours.
Thanks again.
