[sane-devel] umax_pp slow

I got the lastest version (patch) of umax_pp working on the latest 
version of Sane and XSane; those, in turn, run on Red Hat 9 Linux.  I'm 
using an Astra 2000P scanner.  The umax_pp config file uses:  port 
/dev/parport0.  The BIOS is set for EPP (ECP is not available in my BIOS).

When I try to scan something at 300 DPI the scanner does a "four steps 
forward, one step back" dance.  It takes a long time to complete the 
scan.  If I scan at 150 DPI, the scanner does it all in one pass, 
without the "dance."  If I dual boot into Win98 and use the scanner at 
300 DPI, no dance.

Does anyone know how to get my scanner to scan at 300 DPI quickly, in 
Linux -- like it does in Win98?

Thanks for any suggestions!
