You should have set up the printer

[sunman]

You should have set up the printer first with the lpsystem command before you used the lpadmin command.

Try this:
lpsystem -t bsd printservername(NIC_name)
lpadmin -p your_name_printer -s NIC_name!NIC_name_printer
lpadmin -p your_name_for_printer -T unknown -I any
accept your_name_for_printer
enable your_name_for_printer Al
