"Unplugged or turned off": wrong!

[Nicolò Chieffo]

Binary package hint: cups

CUPS thinks that the printer is off (Samsung ML-1640)
steps to reproduce:
- insert the printer USB cable
- open System->Administration->Printers
- click New (the printer is autoconfigured and uses the driver Samsung ML-1640, SpliX V. 2.0.0)
- Print something
IT WORKS!!!
- now unplug the printer
- replug the printer
THE PRINTER WON'T WORK!!! "Unplugged or turned off"

you can make it work removing and readding the printer in the configuration utility

The printer is anyway recognized by lsusb and by hal.
Restarting the CUPS service does not fix the problem.
If I'm not wrong, also a reboot does not fix the problem!

Can you please reactivate the printer via "cupsenable" or with system-config-printer (right-click printer, then click "Enabled")? Now you should be able to print.

Now unplug the printer, wait 5 seconds, and plug it in again. Then attach your /var/log/syslog file to this bug report. Do not compress the file.

[Nicolò Chieffo (yelo3)]

It works, thanks!
here you are the syslog (I removed the lines before the usb disconnection)

[Till Kamppeter (till-kamppeter)]

Can you run "lpinfo -v" on your machine, with your USB printer plugged in and turned on?

[Till Kamppeter (till-kamppeter)]

Please replace your file

/usr/lib/hal/scripts/hal_lpadmin

by the attached file and make it executable with

sudo chmod 755 /usr/lib/hal/scripts/hal_lpadmin

Then unplug and replug your printer. Does it get re-enabled now?

Sorry if I've not tested it yet, I need to come back home because I
have my printer there

[Nicolò Chieffo (yelo3)]

I've received the update
hal-cups-utils 0.6.19+git20090217-0ubuntu2

I've rebooted but the situation is still the same for me.
lpinfo -v shows both hal & usb 'ports':
direct hal:///org/freedesktop/Hal/devices/usb_device_4e8_3292_144QBKAQ412519L__if0_printer_noserial
direct usb://Samsung/ML-1640%20Series

This is strange because when I insert the USB cable, the printer is detected, and a tray icon appears (a printer + a hand lens) but the printer status does not change to 'Inactive'

As you can see in the syslog3 that I will attache, the printer is not re-enabled, it seems that he is trying to add a new printer, failing because he does not find the correct driver

[Till Kamppeter (till-kamppeter)]

The problem was that hal_lpadmin has used different methods to determine whether for a printer reported by HAL there is already a print queue set up for the plugging and unplugging cases

Please replace your file

/usr/lib/hal/scripts/hal_lpadmin

by the attached file and make it executable with

sudo chmod 755 /usr/lib/hal/scripts/hal_lpadmin

Then unplug and replug your printer. Does it get re-enabled now?
