Ubuntu Xenial Docker image with CUPS and additional Epson TM-T20II drivers
It is intended to be used as an AirPrint relay on the Synology NAS, and the local Avahi will be used to advertise printers on the network.
Changes in comparison with the original:
- updated version of Ubuntu
- added prebuilt rastertozj from here
- added tm-t20-orig.ppd is tm-t20ii-rastertotmt.ppd provided on Epson site modifited to use rastertozj filter
- added tm-t20-NP.ppd to make possible print Nova Poshta Zebra Markings 100x100mm from iOS browser (with image scaling)
- added tm-t20-TG.ppd to make possible print Nova Poshta Zebra Markings 100x100mm from iOS PDF file (without image scaling)
This is also a reason to dive deeper into GitHub / Docker / CUPS, so why not? Hope this is helpful to someone.
- 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 created
CUPSPASSWORD: the password for the CUPS admin user
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.
CLI mode running
docker run -d \ --name=cups \ --restart unless-stopped \ -p 631:631 \ -v /volume/docker/cups/config:/config \ -v /etc/avahi/services:/services \ -e CUPSADMIN="admin" \ -e CUPSPASSWORD="admin" \ xyzroe/cups-airprint-epson-tm
- If the
/servicesvolume isn’t mapping to
/etc/avahi/servicesthen 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
