Problem with printer hp930c

Hi! How can I install a printer in qnx?

Configuration of /etc/printcap


I have created /usr/spool/output/lpd and it has write permission.

To print I write in shell:

lpr -PHP930 hello.txt

and it happens the following error:

lpr: connect: conection refused
jobs queued, but cannot start daemon

then I start lpd, and I print again and no errors happen, but the file is
not printed.

I also write in shell:

cat hello.txt >/dev/par1

but character i is only printed in paper.

Can someone help me?
