Apple LaserWriter 12/640 PS - Manual (Page 91)

If the test print doesn’t work
If the test document doesn’t print, check the configuration by following
these steps:
1 Check whether the rlp daemon is running. At the UNIX prompt, type
ps -e | grep rlp
If the process is running, you will see one or more lines of text; it it is not
running, you will see no response.
2 If rlp is running—that is, you saw one or more lines of text in step 1—kill the process
by typing
kill -15 process_number_ from_step_1
3 Make sure the following entry is in the /etc/inetd.conf file:
printer stream tcp nowait root /usr/lib/rlpdaemon
rlpdaemon -i
This line tells inetd to start the rlp daemon automatically when a print
request is made (if it’s not already running).
4 Make sure the following entry is in the /etc/services file:
printer 515/tcp spooler
5 Start inetd by typing the following command at the UNIX prompt:
/etc/inetd -c
6 Repeat the steps in “Configuring HP-UX Version 9.x.”
Configuring SCO UNIX
To configure Santa Cruz Operation (SCO) version 1.2 or later of UNIX,
follow these steps:
1 Log in to the SCO machine as root .
2 Assign an IP address and IP name to the printer, as described in “Step 3: Assigning an
IP Address to the Printer,” earlier in this chapter.
3 Make sure the printer’s IP name and IP address are entered in the /etc/hosts file.
