Digital BW, The Print

Hi,
I just received my new 1290, because my older 1160 broke down (was a 
real workhorse, and excellent quality prints). I hope I will also 
receive my UT2 CFS inkset soon, until then I'd like to know if 
someone knows of a procedure to make the 1290 work with the 1280 
driver. As it is reported, the slightly different drivers will make 
the 1290 print too dark with ther UT2 inks, and instead of tweaking 
the curves I'd rather try to make the 1290 run with the 1280 driver. 
I guess that the hardware should be virtually the same, am I wrong?

regards, Bernie
