If "ls -l > /dev/lp1" doesn't work, then you can eliminate anything related
to the spooling mechanism and file permissions! There is something not
working between Linux and the printer: For some reason, your printer is not
printing out plain ASCII that is being sent to it.

Here are a couple things you should check for:

- Is your printer set up to print ASCII? Some printers, especially PostScript
printers, have to have an option turned on from their menu to let them
autosense between plain ASCII and PostScript files and react accordingly.
To check this, try "copy autoexec.bat lpt1:" from DOS and see if the ASCII
file prints correctly. If it doesn't, then that's probably your problem.

- Are you using polling or interrupts to print? If you are using interrupts,
are they correct? The command "tunelp" under Linux will let you set these.
In general, polling tends to be the more conservative method (works with
most printer setups) than interrupts, but interrupts are more efficient.

if you have a postscript printer, try putting your ascii text through some
ascii 2 ps filter. ap2s is one

#!/bin/sh
#

/usr/local/bin/a2ps -1 -nL -ns -nc -p $* | lpr

How about a Canon BJC-4000, a bubble jet printer? Can I print postscript
file to it? Which filter must I use?

In order to print ps files on any other device, you should use ghostscript to
convert the ps to e.g. eps format.

Well, nearly right.
Ghostscript will convert to several native printer bitmap formats,
not to encapsulated postscript.

oops :-) I meant to refer to 'epson printing bitmap stuff'
