The Samsung smartpanel program starts small but adds 10 meg of memory
usage every minute. Both computers are slowed, little at first, but when
all memory is consumed, they for all intents and purposes stop. If I
wait long enough for them to revive, even mouse and possibly keyboard
action can be sporadic. Strangely, if I use an application without
stopping, then that part continues to run, just don't pick a menu option
or change applications.

The computers recover instantly when I stop the Samsung smartpanel
program. The problems begin to build again the second I start smartpanel
again. Starting and stopping smartpanel is easy as the Samsung install
programs add menu choices for that purpose.

The Samsung Smart Panel program (smartpanel) "allows you to monitor the
machine's status and alerts you when an error occurs during printing."
The printer works fine without Smart Panel so when I want to see
cartridge usage, troubleshooting guide, etc then I can run smartpanel
and then shut it again to keep my computer running.

Now that we've found the bug with help from this list, once you know
about the bug in smartpanel, it is an easy problem to handle.

Samsung's software has some other problems. Since the printer has been
installed XSane complains threateningly about being run as root, even if
I try to use another printer/scanner. It causes concern as it is
possible that XSane is right.

There is a small problem printing messages from Evolution 2.10.3 in
Fedora 7 in that only the body of the message is printed. To print the
entire message with To: From: Subject: then I have to first print to a
.pdf file and then print that. From Evolution 1.4.6 in Fedora Core 2 the
address fields are displayed on screen in a gray shaded box but when
printed (no need for .pdf) the shading is pinkish gray so it is using
red toner unnecessarily.

I reported these problems to Samsung today. They have said they will put
a FAQ on their board about the .pdf work around. I don't know what they
will do about the other problems.

We have used the printer for the past 2 months mostly on 2 Linux Fedora
computers, to a lesser extent on 3 XP machines but have not yet
installed it on another XP, our Vista or Macs. Aside from the above
software problems we are quite happy with this printer.
