lpadmin command fails when using CUPS_LPADMIN_PRINTER env variable

[cruzrealestate]

first of all, great job on this container. does everything I need except, line 102 in your start-cups.sh..

when i run my lpadmin command via an interactive session, my printer gets created. when i try to specify it via the yaml file, i get the message that the file cannot be found..

Can you share the output of your container? It should print out the values it extracted from the ENV. (line 102).
Also, if your lpadmin command relies on an additional file, you will probably need to mount it into the container.

I had the same issue if I put the command between double quotes in my docker compose file
It worked fine after removing the quotes.

CUPS_LPADMIN_PRINTER1 = "lpadmin -p Brother_HL2150N -D Brother_HL-2150N_series -P /etc/cups/ppd/Brother_HL-2150N_series.ppd -v lpd://192.168.1.8/BINARY_P1"
/root/start-cups.sh: line 103: lpadmin -p Brother_HL2150N -D Brother_HL-2150N_series -P /etc/cups/ppd/Brother_HL-2150N_series.ppd -v lpd://192.168.1.8/BINARY_P1: No such file or directory

@silentkiller88 you ran into the issue that docker ENV variables are quite limited (see https://github.com/SickHub/docker-cups-airprint?tab=readme-ov-file#variables-overview)

No quotes, no newlines - not what one would typically expect from environment variables.
