Hi Printer stuck on idle running 10.13?

Hello,

Reset the printing system

If you can’t print to your printer and you’ve tried all other solutions, reset the printing system. This process deletes all printers from your list of printers, deletes information about all completed print jobs, and deletes all printer presets.

Important: First, try other troubleshooting techniques in Printing troubleshooting.

1. Choose Apple menu > System Preferences, then click Printers & Scanners.
2. Hold down the Control key as you click in the list at the left, then choose “Reset printing system” from the menu that appears.
3. After you reset the printing system, the list of printers in Printers & Scanners preferences is empty.
4. Re-add any printers.
