I have the same problem as Zoandroid - and also found that printbot works. I was able to get it working within a minute or two.. just had to select LPD, type in the IP of the printer, and type in a port name (I typed in dell as that's what I set the printer name up as). It worked immediately. I also selected HP Laserjet 4 as a generic print driver for it.. which works for pretty much any laser printer out there.
The only problem, though, is that it only prints files.. it won't print a webpage, similar to a Mac or a PC would.
I can't just click "print" from a webpage.. if I do that, it uses some proprietary samsung software that only seems to want to print to samsung printers, of which I have none.
