I caved in and paid for a subscription to slashdot.
I try to sooth myself by thinking it's supporting the community. The real reason was to block ads.
Well, make that one ad, specifically.
So, I had a query regarding the scan2pdf script mentioned in a comment... but seem to be unable to respond.
For those who care:
# modprobe scanner if there is a fault.
while scanimage --mode binary --source "Automatic Document Feeder" --auto-eject=yes \
--resolution 300 -x 203 -y 280 >/tmp/s2pdf$$.pnm
convert -page letter -compress fax
Money is better than poverty, if only for financial reasons.
