Q: Cannot print my network printer after reset printing system

Hello there, Jack.

It sounds like you're confronting a combination of issues stemming from the reset of your Printing System.  The following Knowledge Base articles offer some great insight on troubleshooting. This first one offers up some pointers on network troubleshooting:

OS X El Capitan: Printing troubleshooting

If you’re having trouble printing, first try these suggestions:

• If your printer is connected to your Mac, make sure it’s firmly connected, plugged into an electrical outlet, and turned on.
• If the printer is on the network, make sure your Mac and the printer are still on the same network, the printer is turned on, and the network isn’t experiencing problems. If the network has multiple printers, check which printer you chose—it may be different from the one you think you chose.
• If you use a shared printer connected to another Mac, make sure the Mac has Mac OS X v10.5 or later, isn’t in sleep, and has sharing turned on. For more information, see Share your printer.
• If your printer is connected to your computer’s USB port, open System Information, then click USB. If the printer’s name appears in the hardware list but the printer doesn’t work, review the printer’s documentation for further troubleshooting information or see Check your device’s USB connection.

If you still can’t print, see the additional troubleshooting information below.

Try to print from another app

Try printing from another app, such as TextEdit. If the problem occurs only in one app, review that app’s documentation for further troubleshooting information.

 

 

Check the printer

Go to the printer and check the following:

It’s turned on and is displaying normal status lights.

It has paper, and the paper isn’t jammed.

It has enough ink or toner.

Its cables are properly connected.

 

 

Add the printer again to create a new printer queue

If the printer is on the network, open Printers & Scanners preferences (choose Apple menu > System Preferences, then click Printers & Scanners). Then, add the printer again to create a new printer queue.

If you can print to the newly added printer queue, delete the old printer queue.

If you can’t add the printer because it doesn’t appear in the list of available printers, it may be turned off, or your Mac may be on different network now. If the printer was shared by another user, the user may have stopped sharing it, or the user’s Mac may be offline. If you don’t manage the printer, ask the person who does for help.

 

 

Check the network

Open Network Diagnostics, then follow the instructions to make sure you’re connected to the network.

If you’re using a Wi-Fi network and there are multiple Wi-Fi networks available, your Mac and the printer might be on different networks. Open the Wi-Fi menu in the menu bar, then try choosing a different network.

To see if the printer you want to use is on the same network as your Mac, open Printers & Scanners preferences (choose Apple menu > System Preferences, then click Printers & Scanners), then click the Add button . If the printer doesn’t appear in the list of available printers, your Mac might be on a different network.

If you know the printer’s IP address (for example, 192.168.1.100), you can try adding it as an IP printer. For more information, see Add or remove a printer.

If your printer is connected to an AirPort Time Capsule or AirPort base station, disconnect your printer from the AirPort Time Capsule or base station, then reconnect it.

 

 

Make sure you have the latest software

If your printer doesn’t support AirPrint, make sure you have the correct version of your printer’s software (also called its printer driver).

If you’re using a printer that another user is sharing, make sure you’re both using the same version of the printer software. To find out which version you’re using, open Printers & Scanners preferences (choose Apple menu > System Preferences, then click Printers & Scanners). Select the printer in Printers & Scanners preferences, click Options & Supplies, then click General. Note the driver version.

If you’re using a network printer or a printer connected to your Mac, make sure you have the latest version of the software for the printer. If you still have problems, try different printer software for your printer.

If you’re using an AirPrint-enabled printer, you can check with the manufacturer to see if there’s a firmware update for your printer model.

 

 

Replace a corrupted printer queue window

If none of the previous solutions work, the printer’s queue may be corrupted. Open Printers & Scanners preferences (choose Apple menu > System Preferences, then click Printers & Scanners), then delete and set up your printer again.

If you have some other printing issue

These steps may resolve printing issues that have no other clear cause:

1. Open the Printers & Scanners pane of System Preferences, then select your printer and click the minus sign to remove the printer from the list.
2. Follow the steps in the previous section to add your printer.
3. If the issue persists, reset the printing system, then follow the steps in the previous section once more.

If the issue remains unresolved, take these final steps to move aside any currently installed printer drivers:

1. Reset the printing system again.
2. Rename the folder at /Library/Printers:
   • From the Finder, choose Go > Go to Folder. Then type /Library and click Go.
   • Click once on the Printer folder to select it, then press Return to begin renaming the folder. Type Printers-old, then press Return to save the new name.
3. Follow the steps in the previous section once more.
