Then for one scan I decided to specify in the Sane dialog for two copies to be printed. It worked fine. Then the next time around, I specified one copy, but nothing happened. I repeated the command several times. Other print jobs could not print either.

You can try with one of the Cups queue manager like gtklpq (is
included in the gtklp package) to restart the print jobs.

I suppose it's a comunication problem with your printer, are you using
a USB or a parallel cable?
