Samsung ML 2150 with samba and CUPS

Setting up a Samsung ML 2150 for use from a Fedora Core 3 systems is
very simple.  Just fire up system-config-printer (or redhat-config-printer
if you're on some other kind of Redhat system), and click around a bit.

queue name: ML-2150

Setting up the printer for use from a windows 2000 professional system
via samba, required a little bit more thought.

To start out, just use system-config-samba, and edit /etc/samba/smb.conf.
This will fairly quickly make it so that the windows machine can send
Something to the printer.  But it may be a text version of what the
windows machine is sending, not the intended graphical version.  Be sure
to allow ports 137-139, tcp and udp, through your firewall (perhaps only
to a list of hosts).

To make it so windows can print to the samsung, I believe with full
functionality on the windows side:

1) Install the PCL version of the driver on the windows machine.
The Postscript version did not work for me (because what the postscript
driver sends is postscript, plus some other gibberish that confuses CUPS).

2) Add something like this to your /etc/cups/mime.types on your Fedora
Core 3 system, just above the "raw print file" section:

# Added by DRS, Thu Nov 11 22:04:16 PST 2004, to make PJL jobs passthrough
application/PJL         contains(0,256,'@PJL JOB')

3) Add something like this to your /etc/cups/mime.convs, again just
above the "raw filter" section:

# Added by DRS, Thu Nov 11 22:04:16 PST 2004, to make PJL jobs passthrough
application/PJL         application/vnd.cups-raw        0       -


...this should make CUPS simply pass through any jobs from the windows
2000 machine.

Update, 2004-12-06:
We've been using this Samsung ML-2150 for a while now.  It's worked well.
Also, the above configuration is working well with both a windows 2000
pro system and a Fedora Core 3 system.  The printer is black and white,
it was priced reasonably (in the ballpark of US$300), and I was pleased to
discover that the printer does duplex printing (both sides of the page)
without having to refeed paper.  :)  We've had one paper jam so far,
and it was pretty easy to resolve.

Update, 2005-06-04:
The printer's still working out great, and we've still had only one
paper jam.  Only thing is, sometimes on the linux side, gimp will print
an unrendered version of a picture.
