Digital BW, The Print

all,
     I'm using a 1280, ut2, originally with qtr 2.4.1 then upgraded to
2.4.3.10 then to 2.4.3.15.  Worked fine the last time I printed (on
2.4.1) about a month ago.  Now, all of a sudden, with settings the same,
I'm only getting 2/3 of the print onto the paper.  I turned off advanced 
printing features, which caused problems on some other epson printers 
I've had in the past.  Any clues as to what else could be happening? 
Nothing else has changed.

thanks,
allan
