Having setup a number of HP LaserJets over the past few years
(including plenty of HP 5 series with Jetdirect cards), I can assure
you that an Ethernet bridge is not required. As long as the TCP/IP
settings are configured correctly, you can print directly from the PC
to the printer. So . . . whats required? There are two parts to
this, software, and network settings.
First of all, youre correct in your assumption that the printer's
default gateway address, subnet address, and IP address would be best
set to be in the same subnet as that of the rest of your internal
There are two ways to change the IP & Default Gateway of the printer.
One way is to use the front panel to configure it. The other is to
use software on a computer to connect to the printer across the
network. The most common software connection is simply telnet which
comes with Windows. (Jetdirect cards have a telnet server built in
and a menu interface to allow configuration changes.)
But before you change the configuration, can any of your PCs get to
the printer right now? (Not necessarily print to it, but at least be
able to send data to the printer and get a response). To test this,
use the ping network diagnostic utility which comes with Windows.
Try opening up a command prompt and typing ping xxx.xxx.xxx.xxx,
putting in the printers IP address for the xs. If you get a reply
from the printer, you can print to it directly. If you dont get any
reply (just timeouts), then the PCs arent able to reach the printer
at all on the network. If you get a "file not found" error, change
directories into windows directory, where ping.exe is found, and try
If you get a reply from the printer, you can try leaving the printer
at its current network address and simply install the network
printing software detailed in the software section below.
If you dont get any reply from printer, then your PCs arent able to
reach the printer on the network. If this is the case, then changing
the IP address and subnet of the printer will be required.
Try using the front panel first, as its the simplest method:
Using this method you can set the IP address, subnet and gateway (its
GW BYTE from the front panel)
While the configuration can be set using the printers front panel,
you may find it convenient to use telnet to connect to the printer
from the network. To do so, youll need to try changing the PCs IP
address temporarily to be in the same range as that of the Printer.
One solution might be to temporarily plug the PC to the hub, if the PC
has a non-wireless Ethernet card. (This avoids any NAT problems that
might arise when going through the RG-1000 and allows you to set the
PCs IP and Subnet to work with the Printer)
The following document discusses TCP/IP setup and using Ping and
Telnet to communicate with an HP printer w/Jetdirect:
Once your PCs can successfully ping the printer, the TCP/IP network
setup should be correctly configured.
Next, the TCP/IP port issue. Windows PCs generally wont print to a
network printer directly (theyre much more accustomed to spooling to
a network queue on a server). To configure a Windows computer to
print directly to a JetDirect-enabled HP printer, youll need to
install some extra software. The CD that came with the printer may
have the Network Printer software, but you might do better downloading
the newest version of HPs free Network Printer Wizard from HPs
The following document at HPs support site discusses how to add an HP
TCP/IP port and also provides a link to the download page for the
software, which is available for most Windows versions including XP:
The wizard software will walk you through connecting the PC to the

Google and using the search tool on HP's website, using terms
