Bug#961458: ippusbxd: Please consider installing a systemd service file by default
I have done this already for Ubuntu in the 1.34-2ubuntu1 package. "dpkg
-L ippusbxd" gives the following 4 non-documentation files in the package:
/.
/etc
/etc/apparmor.d
/etc/apparmor.d/usr.sbin.ippusbxd
/lib
/lib/systemd
/lib/systemd/system
/lib/systemd/system/ippusbxd@.service
/lib/udev
/lib/udev/rules.d
/lib/udev/rules.d/55-ippusbxd.rules
/usr
/usr/sbin
/usr/sbin/ippusbxd
With this USB printers supporting IPP-over-USB will get their ippusbxd
started when plugged in. And as ALL IPP-over-USB support driverless
printing (and scanning if they have a scanner) you can easily print and
scan via the emulated IPP device. Note that for scanning you need SANE
1.0.29 or sane-airscan, and for auto-discovery (independent of whether
you want to print or scan) you need Avahi 0.8.0 or newer.
You can even fax without driver (at least from the command line)
following my simple test described in this GSoC project listing:
https://wiki.linuxfoundation.org/gsoc/google-summer-code-2020-openprinting-projects#support_for_ipp_fax_out
So you simply need to sync with this Ubuntu package ...
Also make sure to overtake the latest changes on system-config-printer
from Ubuntu (version 1.5.11-4ubuntu2 or newer, replace
33_ipp-over-usb-support.patch by
33_no-usb-queues-for-ipp-over-usb-printers.patch), so that
system-config-printer does not try to start ippusbxd or auto-create
print queues for IPP-over-USB-capable printers. Due to not being sure
about Debian's system-config-printer I did the ippusbxd change
Ubuntu-only, also as it was close before our Feature Freeze for 20.04.
