Samsung SCX-4200 and Ubuntu Intrepid Ibex (8.10)
Today I upgraded to Ubuntu Intrepid, and suddenly… my Samsung SCX-4200 printer stopped working 
I recovered my notes from Ubuntu Hardy, where I wrote some operation to make the printer (and the embedded scanner) work. Unfortunately, the “trick” I took from the official Ubuntu forum (see “Samsung SCX-4200 scanner does not work on Ubuntu 8.04 Hardy Heron“) didn’t work anymore, so I spend some time to search for an alternative. And I found it!
You’ve to edit fstab (e.g.: sudo nano /etc/fstab in the terminal) and add this lines at the end:
#usbfs
none /proc/bus/usb usbfs devgid=46,devmode=664 0 0
Now reboot and install the official Samsung driver package for Linux. If you already tried to install it (but it failed detecting the printer), it should be enough to simply reboot: the printer and the scanner will be automatically detected and they will appear in the “Samsung unified driver configurator” (see applications menu).
Enjoy printing 
PS: Thanks (again) to the Ubuntu Forums where I found the solution (even if the topic is dedicated to a different question: Intrepid/Virtualbox/USB

Thanks mate!
This is first time I got my scanner working with Linux / Ubuntu, and I have had this MFP more than a year now. (Printer has always worked for me, and that’s more important.)

Great!
I just spent 20 minutes searching for an answer, and your post saved me.
Thank you very much. It was extremely simple!
Just a suggestion: it’s not necessary to reboot after changing /etc/fstab. A simple
sudo mount -a
is enough.

Note that this is *exactly* the same fix required to get Virtualbox 2.0 working with usb on ubuntu 8.10.

This is awesome… I used this post to install my SCX-4216F and it worked! And using the scanner was virtually the only reason I had a second machine with WinXP on it LOL. Now I can finally convert that PC to Ubuntu! Yay!

Outstanding,
worked exactly as proposed for a first-time ubuntu user. I can not understand, why ubuntu developers do not include this in their distribution frofrom the beginning.
Thanks a lot Ricky

I got SCX-4200 printing working with the great advice above but scanner is still not recognized in 8.10 version. I used to have scanner working in 8.04. Would be greatful for further hints. I did choose to take the 8.04 sane config file during the upgrade to 8.10 if I’m not mistaken… don’t remember the exact file.

OK I reinstalled the driver (same latest .97 version as earlier). After that also scanner started to work, not only printer. So original instruction was perfect together with ubuntu howto install instructions for samsung driver sw.!
