just incase someone has the same error i had when trying to use
the printer drivers for epson alc 1100 on debian/ubuntu: after some
searching through debug error messages i noticed that the shipped
wrapper shellscript (/usr/local/bin/pstoalc1100.sh) will fail with an "arith syntax error"
when doing if test 1 -ge $((Copies));.
the problem is: it uses /bin/sh, which actually points to dash in debian/ubuntu.
and dash cannot cope with this syntax. change the script to use /bin/bash
instead and you will have no trouble printing.
