After Zorin installation, Zorin found my printer and assigned it stock drivers for the Canon TR4500 series, which worked pretty well. Months later I visited Canon support to see if there were any official Linux drivers for my printer and I was surprised to see that there were. After installing the Canon drivers, I was surprised to see that I now had two printers. I renamed the "new" printer "myprinter" and gave it a static IP and made it the default because my WIFI DNS changes the printer IP after a power outage. I rebooted and thought nothing more about it until I needed to print something. I would hit Print... Nothing. Print... Nothing. I looked at the printer settings and found that the jobs were going to the old "printer." Ok, this should be easy enough. I chose "Remove Printer" and then tried to print my doc and it worked! Until I closed Settings and reopened it. Ghost printer was back. I just can't kill the beast. Any ideas? Thanks in Advance!
ON my Brother install the bottom was a network printer....so since i wasnt on a network i made top one default and deleted the lower one
in the 3 dots area to right top click that then remove printer and its gone
Thank you for your reply. I've already tried that countless times and Zorin won't let go of it. I think Zorin caches printers somewhere and there is no obvious way to remove a cache entry. Zorin is storing that printer somewhere for it to keep popping up. I guess this is an impossible problem to solve in Zorin OS.
On the Printer Entry on the Side are these 3 Dots. Click on it and choose ''Delete Printer''.
Thank you, but I have tried that countless times. When I do a "lpstat -p" the ghost printer is not listed. So, where does it come from? Gotta be a Zorin thing. Printer cache?
Is this a Printer only or can it scan and copy, too?
No it's a cups auto-discovery issue.
If you read the Unofficial Manual that I authored you will see that first you need to disable auto discovery and then stop it completely. This happens on all current GNU/Linux distributions, not just Zorin.
So before installing a printer, open a terminal (just type the word terminal in the menu search bar and press enter).
Then:
sudo systemctl stop cups-browsed
then
sudo systemctl disable cups-browsed
Then install:
sudo apt install system-config-printer
Once installed:
sudo system-config-printer
This is the best method to start the interface to add a printer. Zorin no longer ships with it. I have used this method since I learned about it from PearOS days many years ago.
All of the above...
Thank you for your reply. I should have thought to remove the current printer first before adding a "new" one. My tech skills have gotten dusty with age. Your solution worked for me.
Removing the printer does not stop it from re-appearing ... unless you used those commands beforehand.
