Howto : (Clean) Install of a Samsung SPL laser printer under GNU/Linux (without the whole “unified linux driver”)

Printing under GNU/Linux has turned very easy I the last years, by combining an improved compatibility with the even most recent hardware and polished user interfaces to let any user get in with it’s printing server configuration. Well, most of the time there is an opensource driver for your printer, and making it work is then as easy as plugin the USB chord and waiting a tenth of seconds for a green popup to tell you that everything is clean and working… Most of the time.

Towards Samsung, at least for the laser printer I own (a SCX-3200), there is no such an easy install process, because of no tested opensource driver. Configuring your printer will likely drives you to your product’s support page (fr), and maybe will you finish installing the so called “Samsung Unified Linux printing drivers”, what is bad, very bad. This bundle comes with a brunch of middleware you’re likely not to want on your computer (because you may only want to use an USB/network printer). This script also installs it’s own Qt libraries for nothing more than a GUI that is totally redundant with your distrib’ system tools. As of system services and OS’ integration, I doubt those 2011 scripts are aware of the last changes in systemd, selinux, … anyway.

This post will describe how you can make your Samsung printer work as good as on any other platform (using Samsung’s proprietary driver), but without requiring you to install all the burden of the “Unified Linux Driver”.

Step 1: Download and unpack the needed files

This link is working at the date of writing and will download the 0.93 drivers. You can get a link by your own by visiting your printer’s support page at .

Step 2: Install the ppd file for your printer

Once unpacked, you can plug your printer and turn it on. Whatever your distrib, the wizard will fail finding a working driver but will allow you to specify a ppd file. The path to them is :


You just have to pick the good one (scx3200.ppd in my case).

Step 3: Install rastertosamsungspl

PPD files aren’t enough, the Samsung driver mostly consists on a tool that rasters the content you want to print to the Samsung Printing Language (SPL). This binary file is to be found under:


You need to copy this file to your cups filters folder :


Step 4: Configure SELinux to allow rastertosamsungspl to be run

If you try printing something, this kind of message will appear in dmesg :

As explained (in french, sorry…) you can fix it by simply running:

$ grep cupsd /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.pp

And then :

$ /sbin/restorecon -v /usr/lib/cups/filter/rastertosamsungspl

Now your printer should work as expected, without the definitely annoying and useless “Unified Linux Driver” stuff.
