Wireless Printer Setup Errors on Mac — Bonjour Discovery and AirPrint Guide
Warningwireless
Overview
Fix wireless printer setup errors on Mac including Bonjour discovery failures, AirPrint not finding the printer, and manual printer addition via IP address.
Key Details
- macOS uses Bonjour (mDNS) to automatically discover network printers
- AirPrint printers appear automatically in System Settings > Printers & Scanners
- Non-AirPrint printers need manufacturer drivers or CUPS-compatible PPD files
- Bonjour requires mDNS traffic (UDP port 5353) — some routers block this between WiFi clients
- macOS can also add printers via IP using IPP, LPD, or HP JetDirect protocols
Common Causes
- Router blocking mDNS/Bonjour traffic between WiFi devices
- Printer and Mac on different VLANs or subnets
- Printer does not support AirPrint and macOS has no built-in driver for it
- Firewall on Mac blocking incoming Bonjour responses
- USB printer connected to a computer sharing it — macOS does not discover USB shares via Bonjour
Steps
- 1Auto-discover: System Settings > Printers & Scanners > click + > select your printer from the list
- 2If not found: click + > IP tab > enter printer IP address, Protocol: IPP, Queue: /ipp/print
- 3For non-AirPrint: download manufacturer driver from their website, install, then add printer
- 4Check Bonjour: dns-sd -B _ipp._tcp in Terminal to see if the printer is advertising
- 5Reset printing system: right-click in the printer list > Reset printing system, then re-add printers
- 6Verify same network: check IP addresses of Mac and printer are on the same subnet
