1) connected a USB to Parallel converter card.  Printer work fine

2) boot off of Fedora-Xfce-Live-x86_64-33-1.2.iso.  Printer
admin still can't find the card.

3) With

    # modprobe -r lp
    # modprobe -r parport_pc
    # modprobe parport_pc io=0x378 irq=11
    # modprobe lp

the card does show up and you can print to it, but
the jobs instantly disappear and nothing shows on
the printer's status screen


More tests:

4) tried a different parallel port cable with
and without  #3 above.  no symptom change

5) tested with a uboobo live usb: xubuntu-20.10-desktop-amd64.iso
with and without #3 above.  no symptom change
