I am getting blue backgrounds when I print. I have read the reports that the problem is caused by a ghostscript upgrade. I never heard of ghostscript and don't know if I have it. Needless to say that this newby is confused!

You correctly linked to an issue with an update of ghostscript, which causes the problem. The bug is reported.

To work around the issue, try downgrading to the previous version as suggested in the bug report. Although you are a beginner, easiest way is to open the terminal, copy the following command and paste it in the terminal:

sudo apt install ghostscript=9.25~dfsg+1-0ubuntu1 libgs9=9.25~dfsg+1-0ubuntu1 libgs9-common=9.25~dfsg+1-0ubuntu1

This will install the slightly older ghostscript version, replacing the current erroneous one.

Now, any attempt to update the system would also update the package again. To prevent that from happening, you can temporary "lock" the current version. You can do this with synaptic package manager, but it might be easier with a command:

sudo apt-mark hold ghostscript libgs9 libgs9-common

This command locks the currently installed version, i.e., the good one you installed with previous command, preventing it from being updated.

When the bug is solved, you may again want to "subscribe" to the updates. Unlock the current version with the command

sudo apt-mark unhold ghostscript libgs9 libgs9-common

From then on, the packages will again be updated as updates become available in the Ubuntu software sources.

The quality control of the Ubuntu software sources is good. This does not prohibit an erroneous update from slipping through now and then.

This bug was fixed in the package ghostscript - 9.26~dfsg+0-0ubuntu0.14.04.6

i updated it today using 

sudo apt-get update

and then 

sudo apt-get install ghostscript

and do a restart to make sure everything is updated. thanks
