Fix: Printer Not Working After macOS Tahoe Update

A common issue after updating to macOS Tahoe is that your printer stops working. This is almost always due to new, stricter privacy settings that block the printer’s communication with your Mac. Here are the most effective solutions to get you printing again.

1. The Essential First Step: Check Local Network Permissions
This is the most common fix. macOS Tahoe now requires you to explicitly grant “Local Network” access to printer software.

• Go to System Settings > Privacy & Security > Local Network.

• Look for applications related to your printer brand (e.g., rastertoescpll for Epson, HP Smart for HP) and ensure the toggles are enabled.

2. Reset the Printing System
If permissions are correct but the printer is still offline or unresponsive, resetting the printing system can clear corrupted settings.

• Go to System Settings > Printers & Scanners.

• Right-click anywhere in the printers list on the right and select Reset printing system….

• You will need to re-add your printer afterward.

3. Add the Printer Manually via IP Address
If automatic detection fails, manually adding the printer using its IP address is a reliable workaround.

• Find your printer’s IP address from its network settings menu or utility software.

• In Printers & Scanners, click the + button, go to the IP tab, and enter the address.

• For Protocol, try Internet Printing Protocol (IPP).

4. Update Your Printer’s Software
Printer manufacturers have released updated drivers compatible with macOS Tahoe.

• Visit the support website for your printer’s brand (Epson, HP, Canon, etc.).

• Download and install the latest driver package for macOS Tahoe (often listed as macOS 15.x).

5. Check for Conflicting Software
Third-party antivirus and security software (like ESET or SentinelOne) can sometimes block printer access.

• Temporarily disable your security software’s firewall to test if it’s the cause. If printing works, consider switching to macOS’s built-in firewall.

By methodically working through these steps—starting with Local Network permissions—you can almost certainly resolve the connectivity issue and restore your printer’s functionality.
