how to setup HP Jetdirect 3 port print server

[newunixuser]

Hi this is a great medium, any way how do I setup a 3 port print server (HP Jetdirect) print server when I am allready using 2 parallel ports and the serial port for printers and a modem ?
Can I put the main parallel cable to the print server then attach the other 2 printers to the print server and it will work ?
We have 2 D Matrix currently ( Epson,Panasonic) and we need to add 2 more (Epson x2)
Thank you Running SCO open server 5.05 and Enterprise
With AFPS.

Here is a SCO Technical Article on the topic:




How to configure an HP JetDirect EX Plus3 with SCO operating systems. (Ref. #104997)


Description:

I want to set up and use all three ports of an HP JetDirect
EX Plus3 print server and I can only get the first port to work.

Note, if you do not need LPD services, see ta105327, "How do I
configure the HP JetDirect EX Plus3 Print Server to use HPNP?"



Solution:

To get all three ports to work on an HP JetDirect EX Plus3 print
server requires configuring HPJetDirect (hpnpcnfg) in addition to
Remote Line Printing (rlp), *if* you need to use rlp/lpd.
If you do not need to use rlp, see the aforementioned Technical
Article.

NOTE: You do not need to use the HP JetDirect utility for
configuring the HP JetDirect EX Plus3. However, use of the HP
JetDirect utility allows for greater flexibility in configuring
the HP JetDirect EX Plus3. By using HP JetDirect configuration,
you will have an interface script for the printer attached to
port 1 of the HP JetDirect EX Plus3 box. Using RLP as the only
method of configuration means you will have no interface scripts
for any of the printers on the HP JetDirect EX Plus3. If you
don't need an interface script, simply disregard all references
to the HP JetDirect utility and use only the steps for configuring
RLP.

The HP JetDirect EX Plus3 can be configured to use either BOOTP or
a default IP address. You can configure the HP JetDirect EX Plus3
using the front panel, or by using a telnet session from a server.

Once the HP JetDirect EX Plus3 has been configured, take these
steps to configure the SCO operating system to allow printing to
all three ports:

I. Install the HPJetDirect Extended Feature Supplement (efs122) on
your system. The HPJetDirect supplement is only required for versions
of the operating system prior to SCO OpenServer Release 5.0.0 (it
is included in SCO OpenServer Release 5.0.0 and above). Follow the
instructions for configuring an HP JetDirect card. Test and
confirm that you can print to the first port on the HP JetDirect
EX Plus 3.

II. Run the remote line printing configuration utility (mkdev rlp)
to configure remote line printing on the system. You can
configure the printers at this time or you can add or configure
remote printers any time by running "rlpconf". (NOTE: Do NOT run
"mkdev rlp" more than once.) See ta107218, "Configuring SCO UNIX
or SCO Open Desktop remote line printing (rlp)" to configure remote
line printing on systems prior to SCO OpenServer 5. "mkdev rlp" is
not necessary under SCO OpenServer 5, as remote printing will be
configured automatically when you add the first remote printer.

III. After configuring the remote printers, edit the /etc/printcap
file to use the two additional ports on the HP JetDirect EX Plus3
print server. You can use the following examples for the changes
to the /etc/printcap file:

ORIGINAL PRINTCAP ENTRIES:

freddy::lp=:rm=sammy:rp=freddy:sd=/usr/spool/lpd/freddy:
slalom::lp=:rm=sammy:rp=freddy:sd=/usr/spool/lpd/slalom:

MODIFIED PRINTCAP ENTRIES:

freddy|text2::lp=:rm=sammy:rp=text2:sd=/usr/spool/lpd/freddy:
slalom|raw3::lp=:rm=sammy:rp=raw3:sd=/usr/spool/lpd/slalom:

The actual changes required are explained below:

1. Alias the printer name to the port position:

text1=port1 (ASCII) or raw1=port1 (POSTSCRIPT)
text2=port2 (ASCII) or raw2=port2 (POSTSCRIPT)
text3=port3 (ASCII) or raw3=port3 (POSTSCRIPT)

In the above example, the printer "freddy" was aliased to the
second port on the HP JetDirect EX Plus3 and the printer "slalom"
was aliased to the third port.

2. Change the remote printer queue (rp) to the queue name as in
raw1 or raw2 or raw3 for POSTSCRIPT or text1 or text2 or text3
for ASCII. In the above example, the queue for "freddy" was set
to ASCII and "slalom" was set to postscript.

All three ports of the HP JetDirect EX Plus3 should now accept
print jobs.
