We've all run into a printing problem at one time or another. Sometimes a document gets stuck in the queue and won't print, or your Mac can't find your printer on your network.
Apr 25, 2013 You may find there are times when it’s useful to print a list of the files within a specific folder on your Mac. It’s a good way to share a catalog of documents, images, clips, or even fonts. The quick and dirty way is to take a screenshot – Screenshot Plus – One Click Screenshots On The Mac, but it’s not a very elegant solution. Sharing the printers. On Mac OS 10.8, Apple removed the ability to share printers using the Server Admin app. Sharing printers is now easier, however, LPD The Line Printer Daemon protocol (LPD) is a network protocol for submitting print jobs to a remote printer. A server for the LPD/LPR protocol listens for requests on TCP port 515.
Usually one of these steps will get things running smoothly again:
Make sure the printer is properly connected either directly to the Mac or to the same network the Mac is using
Update the printer driver software
Delete and re-add the printer using the Printers & Scanners preference pane
Restart the wifi router and/or printer
But occasionally, these simple fixes are not enough. That's when you have to bring out the heavy-duty tools.
There's a hidden command in macOS that will reset the Mac's printing system. Using it will clear out your list of devices that can print, scan, or fax from the Printers & Scanners preference pane and also do a bunch of behind-the-scenes housekeeping, the details of which you don't really need to worry about.
Because it should be used as a last resort, you won't find the command to reset the printing system in any of the Mac's standard menus, which makes it harder to invoke accidentally. But it's simple to do if you know how.
How to reset the printing system on your Mac
Click on the Apple menu icon.
Click on System Preferences.
Click Printers & Scanners.
Right or control-click in the list of devices on the left side of the window.
Click on Reset printing system...
Click Reset when prompted to confirm that you want to reset your entire printing system.
Enter the password for your administrative account if prompted.
Click OK.
When the reset process is complete, the list of printers and scanners will be empty. You'll then want to re-add your printer.
Click the add button (it looks like a plus symbol).
If a window pops up instead, select your printer from the list of available options.
Click on Add.
