[EN] [SOLVED] Lost Printer

[finotti]

Sometime in the last week or so (since I last used it), my printer, a Brother HL-L2300D, stopped working.  It had worked flawlessly for years.

I then tried reinstalling.  I've installed the official drivers from Brother: https://support.brother.com/g/b/downloadhowto.aspx?c=us&lang=en&prod=hll2300d_us_eu_as&os=128&dlid=dlf006893_000&flang=4&type3=625

I removed the printer from CUPS and installed the drivers:

Code: [Select]

$ sudo bash linux-brprinter-installer-2.2.6-0
Input model name ->HL-L2300D

You are going to install following packages.
   hll2300dlpr-3.2.0-1.i386.deb
   hll2300dcupswrapper-3.2.0-1.i386.deb

Hit Enter/Return key.

Nothing is printed.  I see the printer in CUPS, but when trying to print a test page, I see "Waiting for printer to become available." and nothing prints.  With dmesg I see many instances similar to:
