Digital BW, The Print

I have a 1280, and I've seen this "bump."  Its a place between the 
dark tones and midtones where a small change of tonality on the 
screen causes an abrupt change in the print.  Usually you can get 
around it by a small change in the brightness curve.  It's a pain, 
however.  Per your advice, Paul, I'm using Tyler's curves.  Which 
curves did you say were the least problematical?

I'm wondering if we might be able to use the 1270 driver on the 
1280?  I've done this for years with HP laser printers--if theres a 
problem with the Laserjet n, use the driver for an earlier printer.  
If the 1280 is just the 1270 with some smaller-scale movements to do 
2880 dpi, then it might work.  Has anyone tried this? 

Also, has anyone used Piezography on the 1280, and does it have the 
tonal "bump" that the Epson driver has?
