Digital BW, The Print

Berne-

I'm a PC user, but I think it works the same on the MAC. The piezo 
driver doesn't use the printer spool functions. It is using the 
export function that (as far as I can tell) puts the file in RAM.

This might be another reason that everyone advises making one print 
at a time. I have paper feed issues if I make multiple prints, so I 
haven't run into this, but I used to get a similar problem with my 
Kodak dye sub until Kodak wrote a raster driver that let you spool 
unlimited numbers of prints. With the Kodak printer, you could 
improve the number you could "spool" by adding memory to the PC or 
the printer. You might be able to test this by REMOVING some ram and 
seeing if the number you can "spool" goes down. If it does, then it 
might be worth while to add some ram?

Good luck,
