Digital BW, The Print

Doing my own printing the MIS quad and hextones with my 2 Epson 1200 I
helped a friend in Austria to install the MIS VM inks during last weekend.
He had bought a 1290 printer for which there are no Roarke curves available.
We tried to work araund this problem by following the advice on the MIS
workflow site to install the driver of the 1280 to run the 1290. This driver
is available only in English language from the US Epson site, because the
1280 apparently wasn�t marketed in Europe.
My friends brandnew G4/Mac OS 9.2 German version refuses to accept the 1280
driver.
Is someone out there knowing the problem and how to handle it?

Thanks in advance
