CUPS Synology container with driver for Brother HL-3070CW pre-installed based on quadportnick/cups-airprint. This CentOS 7 based image runs a CUPS instance that is meant as an AirPrint relay for printers that are already on the network but not AirPrint capable.
Note: This works only on Synology DSM NAS devices, as we use the avahi daemon from the NAS.
- No other printers should be shared under Control Panel>External Devices>Printer so that the DSM's CUPS is not running.
Enable Bonjour service discoveryneeds to be marked under Control Panel>Network>DSM Settings
/config: where the persistent printer configs will be stored/services: where the Avahi service files will be generated
CUPSADMIN: the CUPS admin user you want createdCUPSPASSWORD: the password for the CUPS admin user
- Use Host network.
631: the TCP port for CUPS must be exposed
CUPS will be configurable at http://[diskstation]:631 using the CUPSADMIN/CUPSPASSWORD when you do something administrative.
If the /services volume isn't mapping to /etc/avahi/services then you will have to manually copy the .service files to that path at the command line.
- CUPS doesn't write out
printers.confimmediately when making changes even though they're live in CUPS. Therefore it will take a few moments before the services files update - Don't stop the container immediately if you intend to have a persistent configuration for this same reason
