ML-2250 Printer Problems

I had some difficulties with support for my Samsung ML-2250 printer before, and with the Leopard install they seem to be back. Leopard appears to detect the printer automatically, but on startup and whenever I try to print, the printer just spits out sheets with random bits of PostScript on them.

This looks to be the core of the problem: the printer driver describes itself as "Samsung ML-2250 Series PS", but according to the printer manual PostScript is an optional extra that I don't have.

So maybe I need to revisit the helpful comment I got about Foomatic…
