How to execute a specific command before printing?

[SeeleVolleri]

Hi guys, I am using HP Laserjet 1020 plus (hp laserjet 1020), the hplip propriteriy driver requires manual execute hp-firmware to download the firmware, then start printing. Otherwise the printer just sitting there watch me find why it doesn't work.

System Information:

• OS and its version: [Debian12 running docker olbat/cupsd:latest(PRETTY_NAME="Debian GNU/Linux trixie/sid")]
• Application [cups webui print test page]
• CUPS version [e.g. 2.4.10]

Additional context Docker running using

$ docker run -d --name=cups \
--net="host" \
--privileged=true \
-e TZ="Asia/Shanghai" \
-v /dev:/dev \
-v "/etc/avahi/services:/etc/avahi/services" \
-v /var/run/dbus:/var/run/dbus \
olbat/cupsd

Make the udev rule on your host to run the command you need upon connecting. You can check such a rule in either hplip or foo2zjs.

I know, it's just a scenario... not possible in CUPS?

Looks like a job for Tea4CUPS, more specifically with a prehook. The Debian Wiki has an entry with a description of the capabilities of Tea4CUPS with examples.
