Package: cups-server-common
Version: 1.6.3-1
Severity: normal

Dear Maintainer!

I have the HP Laserjet P2055 connected via USB. If I submit a job and the
printer is not connected, the printer status goes to pause. If I connect the
printer to the usb ports, the status does not change. I have to enable the
printer manually. This is not what I expect of the system. If I plug a printer
and the printer is enabled, I always intend to enable and use this printer.

It would be great if a printer that is already installed in cups goes to status
idle automatically after connecting it. I think Debian should provide a
solution for this. May be Debian does but it does not work with my special
printer. The package system-config-printer-udev does not help.

I attach some udevadm outputs that may help.


Partial solution:
--------------

I tried to solve this problem with an udev rule. The rule

ACTION=="add" SUBSYSTEM=="usbmisc", KERNEL=="lp*",
RUN=="/usr/local/bin/cupsenablebyserial.sh %s{serial}"

calls a script cupsenablebyserial.sh. It works almost fine. But I need the
serial as a parameter to be able to enable the correct printer. For some
reasons the %s{serial} is empty.

The helper script should be something like this:

#!/bin/sh
if [ -z "$1" ]
  then
    echo Failed to enable usb printer. /usr/local/bin/cupsenablebyserial called
withoud a valid serial. Please report this bug to debian team and help them to
fix this. >> /var/log/cups/error_log
    exit
  fi
printer_name=$(lpstat -v | grep $1 | awk '{print $3}' | sed s/://g)
if [ -z "$printer_name" ]
  then
    echo Failed to enable usb printer with serial $1. Did you install the
printer with this serial? >> /var/log/cups/error_log
    exit
  fi
cupsenable $printer_name

Udevadm info starts with the device specified by the devpath and then

A rule to match, can be composed by the attributes of the device

Thank you for your report, Hartmut.

Automatic detection and setting up a USB-connected printer is now a
reality on Debian 11 with a modern device and the aid of ipp-usb and
cups-browsed. Therefore I am closing this report.

(Legacy devices, such as yours, will be handled at a later date using
a Printer Application).

Regards,

Brian.
