Let's back up a step or three. First of all did you run
cat <filename> > /dev/lp0
as root or regular user. Printer services are installed as root user
with superuser privileges. So, the above command must be run by the
superuser. If you are not superuser, you must use the print utilities.
As *root* user, try this;
lptest > /dev/lp0 (or /dev/lp1 depending on your installation)
This should send 16,000 characters to the printer, or ~200 lines. See
man lptest for options.
If this test fails, then the printer installation itself is bad (since
the printer still tests ok).
If the above worked, kill and restart lpd, then run (as root)
lptest | lpr
If this works, you're good to go. If it doesn't, then the problem lies
with the print software or configuration. These two tests should at
least narrow the area of search.

Is this what you have? IBM Pro24 or Epson emulation e.g.? See below

Does this file *exist*? If not, anything sent to this printer will
vanish.

Since there is no if (input filter), the default is ASCII/DOS style
character output. That could confuse a PS printer.

Luke, I haven't run into it myself yet, but as I understand, lpd creates
a lock file if a job terminates abnormally. You may have to clear the
spool before you can print anything else.
So, in summary:
run lptest > <dev> to check hardware setup; if it works go to the next
thing.
run lptest | lpr to check software/config.
Remember to do these tests as superuser.
