Symptom:
Cannot print from CT2020 to the receivers printer (.49)
Problem Statement:
If CT2020 cannot send print jobs to the printer, usually due to the printer having a hardware issue, CT2020 will stop sending print jobs and will disable its CUPS program (CUPS acts like a print server).
Even when the printers hardware has been fixed the CUPS does not automatically turn back on and will require user intervention.
Resolution:
1. Log into the stores CT2020
2. Go to the Utilities menu
3. Select option Cancel CT2020 Print Jobs
4. Select Shell
5. Run this command lpstat -t
6. This will list all printers and display the printer status (see photo)
7. Locate the printer name that reads disabled (printer backroom disabled since..)
8. Run this command to re-enable the CUPS program sudo /usr/sbin/cupsenable backroom (*or other name of the printer needed)
9. Type in Exit and test print jobs
