The Xerox Phaser 6125N printer is a great piece of work, however it is not supported by default under Linux (Ubuntu 11.04 x64).

Getting it to work

You can how-ever use little trick to adjust the provided driver of the ​Fuji-Xerox DPC525A CUPS ppd in such a way that is also works fine for this printer. As described over here ​http://ubuntuforums.org/showthread.php?t=1205253.

New Features

This steps how-ever does not alter the ppd file in such a way that it is automatically detected, the attached files have two new features:

1. provide autodetect support for both USB and UTP printing.
2. Set the feeder to 250 pages by default, instead of none.
3. Removed the non-standard and unsupported FXPostCard.

Download & Install

For the (Debian Ubuntu) folks

1. Download cups-xerox-phaser-6125n-1.0.0.deb
2. $ sudo dpkg -i cups-xerox-phaser-6125n-1.0.0.deb

When running 64bit you will also need to install a bunch of 32 bit libraries to get it working:

1. $ sudo apt-get install libc6-i386

For the non-deb (Fedora, OpenSuSE) folks

1. Download cups-xerox-phaser-6125n-1.0.0.tar.gz
2. $ sudo tar -C / --no-overwrite-dir --keep-newer-files -xvzf cups-xerox-phaser-6125n-1.0.0.tar.gz

When running Fedora 18,19,20,21,22,23,24 64bit you will also need to install a bunch of 32 bit libraries to get it working.

1. $ sudo yum install /lib/ld-linux.so.2 /usr/lib/libcups.so.2

When running Fedora 25 64bit you will also need to install a bunch of 32 bit libraries to get it working

1. $ sudo dnf install /lib/ld-linux.so.2 /usr/lib/libcups.so.2

Troubleshooting

The package might create insecure permissions, causing the filter to fail as shown in /var/log/cups/error_log:

 E [21/Apr/2014:13:20:23 +0200] Phaser-6125N: Directory "/usr/lib/cups/filter" has insecure permissions (040775/uid=0/gid=0).

$ sudo chmod 0755 /usr/local/cups/filters

Debugging Fedora 27

Starting from Fedora 27 the printer stopped working. Causing me to dive deeper into the magic world of printing.The printer has HBPL support. Yet the HBPLv1 driver from ​foo2zjs does not give me any output at all.The HPBLv2 driver at ​foo2hpbl does not work, giving error code PDL ERROR 016-720. I am currently using the ​Fedora printer debugging guide to find out how-to get the original driver - which seems to send a modified version of postscript - to work again.

I gave up. Swapped printer for older well suported SamsungML1750 printer attached to my FreeBSD Server.

Windows 10 driver Support

There is no Windows 10 driver Support for the Xerox Phaser 6125N anymore, yet the ​Fuji-Xerox DPC525A driver works fine. Do mind you need to change some options like telling tray 1 has an 250 sheet feeder and set memory support to 64MB, but at least you do not need to buy another printer.
