HOWTO Install Samsung Unified Printer Driver

i have a samsung scx-4725fn mfp.
everything worked ok except the root thing for the scanner.
i tried your idea:
a: in a terminal, type "sudo chmod -s /usr/bin/xsane"
b: sudo edit /etc/sane.d/dll.conf, and comment out (add a "#") in front of the line that says "smfp" (probably the last line).
If you only do (a) and not (b), xsane will crash.

my scanner is not detected anymore.

is there anyway to reverse command "a"?

command "b" i can change back. should there be " around the #?

i am not complaining. any tip or help would be appreciated.

thank you

sudo chmod +s /usr/bin/xsane

thanks for the quick reply tweedledee.

tried that but it didn't work.

uninstalled xsane and reinstalled xsane. still nothing. then went to configurator and clicked on scanner and there it was. then properites, can do basic scan from there, which will work for me at the present time.

later a fresh install will get me back to the "root" problem, but for now all is well.

why is it a problem to run xsane in root?

thanks again for your help:popcorn:

Running anything unnecessarily as root is potentially a security problem; in this case, it means that if xsane has a security bug that would normally only provide limited system access, running as root might give someone full access. However, if you keep your system patched, this is probably minor.

It's more likely to be a pain because the resulting images are owned by root, so you have to change the owner to move/delete/change the files (or do all those things as root as well).

I'm glad it's working for you in some fashion. I wish Samsung would spend less time on a "Unified" driver and more on a "simplified" driver.

I just got a Samsung CLP-300N and have it connected via network (it can connect either network or USB direct).

I downloaded the latest unified driver from Samsung's site :
20070424145947906_UnifiedLinuxDriver.tar.gz

I extracted it and the ONLY thing I did was change the permission so I could edit it and changed that first line to bin/bash instead of bin/sh

Then I did sudo ./install.sh and away we went. GUI came up and printer installed perfectly.

Maybe teh new unified driver is fixed?

All: as pointed out in other forums posts and on slashdot, this installer also changes permissions on some directoires that it should not. This is not a huge deal, but should be changed back.

You will need to reset the following files and directories to be owned by root instead of by your user (sudo chown root:root ..., where ... is each of the paths below):
/usr/
/usr/lib
/usr/lib/cups
/usr/lib/cups/backend
/usr/lib/cups/filter
/usr/lib/cups/filter/pscms
/usr/lib/cups/filter/rastertosamsungpcl
/usr/lib/cups/filter/rastertosamsungspl
/usr/lib/cups/filter/rastertosamsungsplc
/usr/lib/sane
/usr/lib/sane/libsane-smfp.so.1.0.1
/usr/lib/libmfp.so.1.0.1
/usr/share/ppd/custom/CLP-550ps.ppd (you will have a different ppd file here for a different printer, use "ls -l /usr/shar/eppd/custom" to see the corret file (the one owned by you instead of root))
/etc/
/etc/sane.d
/etc/sane.d/smfp.conf


reiki: thanks for the update, I've noted it in the original post.

Confirming .:. I did have to reset those ownerships, even with this newest driver install.

I didn't see anyone else mention it, but the install script also sets OpenOffice to run as root, just like xsane. To undo the change to OpenOffice, run this command:

sudo chmod -s /usr/lib/openoffice/program/soffice.bin

I've not actually experienced this occuring, though I've seen other reports of it recently. I'm not sure why some people seem to observe this, perhaps it's a "feature" of a newer version of the driver than I'm running. I've added a note in the original post.

I just checked my machine regarding the openoffice thing and it is indeed +s.
I am checking to see if I have another ubuntu install where I haven't installed the samsung driver yet...
