+CUPS printing setup for Arch Linux.
+
+## Installation
+
+```bash
+sudo pacman -S cups cups-pdf
+```
+
+## Enable Services
+
+```bash
+sudo systemctl enable --now cups
+sudo systemctl enable --now avahi-daemon
+```
+
+Avahi enables automatic network printer discovery.
+
+## Configuration
+
+### Web interface
+
+Access CUPS admin at: http://localhost:631
+
+### Add printer via CLI
+
+```bash
+# List available printers
+lpinfo -v
+
+# Add a printer
+lpadmin -p PrinterName -E -v "uri" -m "driver.ppd"
+
+# Set default printer
+lpoptions -d PrinterName
+```
+
+### Network printers (auto-discovery)
+
+With Avahi running, network printers should appear automatically. If not:
+
+```bash
+# Install nss-mdns for .local hostname resolution
+sudo pacman -S nss-mdns
+
+# Edit /etc/nsswitch.conf, add mdns_minimal before resolve:
+hosts: mymachines mdns_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] files myhostname dns
+```
+
+## Print to PDF
+
+The `cups-pdf` package creates a virtual PDF printer:
+
+```bash
+# Print to PDF (outputs to ~/PDF/)
+lp -d cups-pdf document.txt
+```
+
+## Useful Commands
+
+```bash
+lpstat -p              # List printers
+lpstat -t              # Full status
+lp -d PrinterName file # Print file
+cancel <job-id>        # Cancel print job
+lprm <job-id>          # Remove print job
+```
+
+## Troubleshooting
+
+```bash
+# Check CUPS status
+systemctl status cups
+
+# View logs
+journalctl -u cups -f
+
+# Restart CUPS
+sudo systemctl restart cups
+```
