My problem was solved a long time ago by a Xerox technician who came on site.
But you should try to add a new printer and choose by "IP address" instead of "default".
And choose "HP Jetdirect - socket" under Protocol.
My system is in french but you can see the settings below.Hope this will help you to solve your problem.
Did you find a fix to this?
I'm in the exact same situation as you.
I've already updated the drivers to the lastest.
Hello j.vautherin@genoudsa,
It could be an issue with your driver, have you tried uninstalling and re-installing the latest driver from our website? You can find the most up to date drivers here.
When I print a document from Microsoft Outlook the printer always print an additional page with the text below:
@PJL ENTER LANGUAGE = POSTSCRIPT
The printed document is fine but this additonnal page is really anoying...
This issue only appens with MacOs High Sierra (XeroxDrivers_5.6.0_2187).
Can someone help me to disable this printed message?
