After installing hplip 3.15.6 printer is sometimes not recognized after reboot

[chris pollock]

HPLIP was automatically updated on 11 June 2015. During the upgrade instructions were carefully followed however at the end the printer was not recognized. The upgrade was attempted again and it was then noted that it was required to turn off then on the printer for it be be recognized at the end of the install. Today, 26 June 2015 after a reboot caused by a video freeze the printer was not recognized (firmware was not downloaded during boot as usual) and running hp-setup shows printer not recognized even after turning the printer off then on several times and also unplugging and replugging it in to the usb port. I have not yet gone through these steps:

=> Run the command "hp-uninstall" to cleanly uninstall HPLIP. Remove plug-ins too when prompted.

=> Install the latest (or already downloaded 3.15.2 run file)

=> Remove all the existing queues by running the command "hp-setup -r"

=> Re-configure the queue by running the command "hp-setup". This step will also prompt for installing the plugin. Follow the prompts to install the plugins.

=> Try printing to the queue named HP_LaserJet_1020

After going through all the steps above the printer is again functional. Note: during the step to install the hp driver besides unplugging and replugging in the usb cable I have to additionally turn the printer off and on. Once this is done the driver installs correctly.

Install the latest (or already downloaded 3.15.2 run file) <----Ignore the 3.15.2 noted here, I'm working with the current version 3.15.6.

Tonight I got to print something - printer shows job started and then completed however nothing happens. I turned off and the on printer, tried again, nothing. Changed USB cable port on hub, nothing. Ran sudo lsusb, printer is seen, ran hp-setup printer not seen. Ran hp-doctor, printer not seen. All output is below. This is becoming absurd!!

FWIW I've completely removed hplip and removed the printer. Set it up again using the CUPS interface:

Description: HP LaserJet 1020
Location:
Driver: HP LaserJet 1020 Foomatic/foo2zjs-z1 (recommended) (grayscale, 2-sided printing)
Connection: usb://HP/LaserJet%201020?serial=JL1F0DC
Defaults: job-sheets=none, none media=na_letter_8.5x11in sides=one-sided

It is working fine.

Status changed to 'Confirmed' because the bug affects multiple users.

With hplip 3.15.11 I still have the same problem.
Every time I have to boot the computer I need to uninstall and reinstall hplip
