This Ubuntu-based Docker image runs a CUPS instance that is meant as an AirPrint relay for printers that are already on the network but not AirPrint capable.

• Included drivers HP, Samsung, Canon, Xerox, etc.

docker run --name airprint --restart unless-stopped --net host xirixiz/synology_airprint:latest

• sudo synosystemctl stop cupsd
• sudo synosystemctl stop cups-lpd
• sudo synosystemctl stop cups-service-handler
• sudo synosystemctl disable cupsd
• sudo synosystemctl disable cups-lpd
• sudo synosystemctl disable cups-service-handler

• CUPS will be configurable at http://[host ip]:631 using the admin/admin.
• Make sure you select Share This Printer when configuring the printer in CUPS.
• After configuring your printer, you need to close the web browser for at least 60 seconds. CUPS will not write the config files until it detects the connection is closed for as long as a minute.

• sudo synosystemctl start cupsd
• sudo synosystemctl start cups-lpd
• sudo synosystemctl start cups-service-handler
• sudo synosystemctl enable cupsd
• sudo synosystemctl enable cups-lpd
• sudo synosystemctl enable cups-service-handler

• /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 created - default is admin if unspecified
• CUPSPASSWORD: the password for the CUPS admin user - default is admin username if unspecified

• Must be run on host network. This is required to support multicasting which is needed for Airprint.
