Background

I've had this printer for many years and it's been great.  Recently I upgraded my desktop motherboard and the new board does not have a printer connector.  A short term fix was to get a USB to Printer cable.  A better solution is to cable the printer to my 2Wire DSL router and connect via LAN.  The reason this is better is that now a wireless laptop can connect directly to the printer instead of going through the desktop via. a share printer.  This will work for the laptop even if the desktop is down, like during a power failure.

27 Feb 2013 - using the LAN to drive the printer is noticeably faster than the parallel port and faster than the USB-to-Printer cable.

June 6, 2017 - Getting 81.0180 EIO 1 ERROR.
This can be fixed by turning the power off and then back on.  This seems to be needed every other day. 
Since a working printer is mandatory for my business I got the HP LaserJet Pro M501dn printer which is almost exactly the same printer.

Replacing the HP jetdirect 625n LAN interface probably would fix it.

Installing this used HP jetdirect 625n LAN interface card failed to print anything.
The card is probably bad. BUT . . . .
After re-installing the old HP jetdirect 625n LAN interface card, so far the printer
is working and has not shown the EIO 1 error.  Will check again tomorrow.

I have one on order for $20 to see if that solves the problem.  Until I've used the new M501dn printer I won't know if it's a full replacement.

My HP 6200 scanner was the best one I ever had and there's no replacement scanner, for a reasonable price, that comes anywhere near it's performance so I'm cautious about how well the M501dn will work.

As a short term fix I got a new HP LaserJet Pro M501dn ("d" for duplexing and "n" for networking).

Upgrades

The unused DB-9 jack is marked Accessory.

The RS-232 cable is used when a laptop is used in place of the desktop computer and there's no other way of connecting.

Below the RS-232 jack/cable is a DIN jack marked FIR.

The Printer cable has a USB adapter on the other end to allow a USB port to make the connection.

An optional hard drive is installed in the EIO2 slot..

A LAN cable goes to the at&t 2Wire DSL router allowing direct wireless connection to the printer from any computer on the 802.11 WiFi network.

The LAN card is an HP jetdirect 625n is installed int he EIO1 slot.

The optional duplexer is installed and is a great thing.  It cuts the paper useage almost in half.

The duplexer rear door is broken and so has been removed.

Enter the IP address of the printer you found on the printer configuration printed page above (192.168.1.71).

I've added a 3 in the Port Name field because I've already used the names IP_192.168.1.71 for a Post Script (PS) printer and IP2_192.168.1.71 for a PCL6 printer so am using IP3-192.168.1.71 for this description.
