Where do I put this PPD file that I uncompressed? I looked in /usr/share/ppd and all I found was HP and all the ppd files in there were compressed. Should I create a Samsung directory and put the ppd file in there? Thanks.

Yes,but leave it compressed,all mine are.

This is friggin insane, I did that and now samsung shows in the make and driver lists but the usb ports no longer work for the printer. Everytime I figure out one thing something else changes. I just hooked the parallel cable back up and tried but there is no parallel port option in the device list during the localhost:631 setup in the browser. What else can I do?

Perhaps try
#modprobe parport

I tried that and i get nothing in response. This is from rc.modules if that helps.

#### PC parallel port support ###
if cat /proc/ksyms | grep "\[parport_pc\]" 1> /dev/null 2> /dev/null ; then
echo "parport0 is built-in, not loading module" > /dev/null
else
if [ -r /lib/modules/$RELEASE/misc/parport_pc.o \
-o -r /lib/modules/$RELEASE/misc/parport_pc.o.gz \
-o -r /lib/modules/$RELEASE/kernel/drivers/parport/parport_pc.o \
-o -r /lib/modules/$RELEASE/kernel/drivers/parport/parport_pc.o.gz ]; then

#### Parallel printer support ###
if cat /proc/ksyms | grep "\[lp\]" 1> /dev/null 2> /dev/null ; then
echo "lp support built-in, not loading module" > /dev/null

/sbin/modprobe lp

You could probably check:

$ dmesg | grep parport

If nothing shows up you should check your BIOS.

However, I'm not certain this is your (only) problem as I have successfully performed
a test install of a Samsung ML-1210 on both USB and parallel ports.

I have not downloaded anything in particular for this printer.

These are the packages I currently have installed that are cups/foomatic/ppd related:

Do you have any (other) way of verifying that either your USB or parallel ports are currently 'working' (in Linux)?

I receive nothing when i do dmesg | grep parport, as user or root. I thought the USB ports were working because I got to the point where when i tried to print something the printer would make noise and start up but nothing would print. I then switched back over to Parallel port. I did have this same printer working with the 2.4 kernel with no problems on same hardware.
