Two-sided printing on Photosmart 8450

Asked by Patrick Bauer

I have a Photosmart 8450 which is capable of printing two-sided copy MANUALLY, but won't pause after printing side one to give me the opportunity to turn the paper around. It just keeps on printing side two on new sheets of paper.. I am running Ubuntu ver 18.04.1 LTS and hplip 3.18.9. Two-sided printing works fine in the Windows7 environment.

As of today my printer still does not print two-sided copy. The HP 8450 has the capability of printing two-sided copy but the paper must be turned manually. In Windows, it prints one side then pauses while you turn the paper, after which it continue printing the second side. In Ubuntu (GNOME desktop) it doesn't pause, but continues printing the other side on a new sheet of paper. Of the three answers provided, the first does not work, while the other two answers don't apply as I have neither an ECHO device nor am I using AOL.

It has come to my attention that the problem may be related to the GNOME desktop no longer having thr "systray", which causes the HPLIP program to cease running. If this is the problem, is there a workaround?

I found these messages:
Under [Installed CUPS printer queues] Warning: Fail to read ppd=/etc/cups/ppd/Photosmart_8400.ppd file

Under [Permission] Warning: Insufficient permission to access file /etc/cups/ppd/Photosmart_8400.ppd

                                     Warning: Could not complete Queue(s) configuration check

Is there a problem with the GNOME desktop and the "No Systray" message? Is there a workaround?

You guys never answered my question except with advice that either didn't
work or didn't apply. Then you cancel my question. Thanks for the help.
