I'm using a Umax 3400 scanner on a Win XP machine. Installing the VistaAccess
software was impossible according to instructions. I'm stuck using the Scanners
and Camera Wizard in Control Panel, and I can't find the "descreen feature".

Also, if I'm scanning a lot of old B&W pictures, should I scan at 300 dpi or 600
dpi? We would likely take a CD up to Wal-Mart to print some shots up, and maybe
enlarge them. I'm scanning into TIF images; and if I have to, I'll make copies
into JPEGs so the CD will work at Wal-Mart.

I can't answer this.

Some prints can provide extra photo detail when scanned at a setting
above 300ppi. Others will max out below 300. If you want to be
certain that you capture everything regardless of current needs,
resample a 300ppi scan to 200% and compare the result with a 600ppi
scan of the same image. I posted similar concerns some time ago; you
might find the answers I received helpful. Search Google Groups for
"Epson 4870 resolution setting vs true resolution" and read the first
thread that comes up.

If your only goal is today's Walmart print job, you need to consider
whether you'll be printing the new prints at the same dimensions as the
old ones. I have no idea what the "native" ppi setting for Walmart
prints would be, but it's much more likely to be closer to 300 than
600. If it even existed in the first place, the extra detail from a
600ppi scan would be wasted in a 1:1 reprint. However, it would be
quite noticeable if your reprints were double the size of the
originals. If you'll be printing *smaller* than the originals, just
stick to 300ppi scans, as even that will contain more detail than the
reprints will provide.

Sorry I can't offer more specific numbers or advice, but that's all I
know. :) Maybe someone else will add to my post or correct any
misconceptions.

Good luck,
