I finally managed to delete the unwanted printer by deleting CUPS
from the machine running it. However, lpr still does not work. The
problem is that no default printer is defined.

        $ lpstat -d
        no system default destination

I'm using a HP Laserjet1320 with USB printer under Chimaera.

I try to set the default:

CUPS -> Printers lists my printer as:

        HP_LaserJet_1320_series

So I set that printer as to be default:

        $ sudo lpoptions -d HP_LaserJet_1320_series
        copies=1 device-uri=hp:/usb/hp_LaserJet_1320_series?serial=00CNL1F33212
          finishings=3 job-cancel-after=10800 job-hold-until=no-hold
          job-priority=50 job-sheets=none,none marker-change-time=0
          media=na_letter_8.5x11in number-up=1 output-bin=face-down
          print-color-mode=monochrome printer-commands=AutoConfigure,Clean,PrintSel
          fTestPage printer-info='HP LaserJet 1320 series'
          printer-is-accepting-jobs=true printer-is-shared=true
          printer-is-temporary=false printer-location='Local Printer'
          printer-make-and-model='HP LaserJet 1320 series Postscriipt

          printer-state-reasons=none printer-type=8425556 printer-uri-suppo-
          rted=ipp://localhost/printers/HP_LaserJet_1320_series_USB_00CNL1F332>
      _HPLIP sides=one-sided

But there is still no default value

        $ lpstat -d
        no system default destination

When I specify the printer by providing lpr with -P option:

        $ lpr -PHP_LaserJet_1320_series test.txt
        lpr: HP_LaserJet_1320_series: unknown printer

I do lsmod to make sure that ppdev, parport, parport_pc modules are loaded.

CUPS lists only one other driver for the LaserJet 1320 which is pcl3,hpcups 3.21.
But when I use it I get error: Unsupported document-format
"application/vnd.cups-command".

        $ a2ps testFiles/test.txt
        [testFiles/test.txt (plain): 1 page on 1 sheet]
        /usr/bin/lp: Error - No default destination.
        [Total: 1 page on 1 sheet] sent to the default printer

        $ lpq
        no entries
