i have an hpdeskjet722c connected to my computer through a parallel port. i selected "Parallel port support", "PC-style hardware", and "Parallel printer support". when i run cat test.txt > /dev/lp0, i receive the error message -bash: /dev/lp0: Permission denied. anybody got a solution?

How about cat test | lpr. Does that work?

# cat test.txt | lpr
lpr: error - no default destination available.

do you by any chance know how to make a default destination available?

Looks as you don't haven't chmod'ed /dev/lp0 right. Try doing that from root.

Some printers don't like plain ASCII data, and need it in their scary format. Anyhow, use CUPS. It helps.

:arrow:

emerge cups
:arrow:

emerge gimp-print-cups
:arrow:

emerge gs

/etc/init.d/cupsd restart

Then go to http://127.0.0.1:631/admin and follow on from there.

the reason i'm trying to get printing up with cat is to test it before i actually install cups (which is what the gentoo printing guide suggests). i was running cat test.txt | lpr as root before. so far what i've done to get it working is emerge cups, emerge foomatic (i don't think that affects cat but just mentioning) and enabled Parallel port support, PC-style hardware, and Parallel printer support in the kernel (not compiled as modules). btw the link doesn't work

i've checked the directory /dev and there doesn't seem to actually be an lp0 (or lpanything, for that matter). is that my problem? did i miss something in the kernel?
