If you like to do it all on your own see for example
http://en.opensuse.org/SDB:Using_Your_Own_Filters_to_Print_with_CUPS
"Adding Additional Filter Stages to the Default CUPS Filter System"

The additional filter could be something like
-------------------------------------------------------------------
#! /bin/bash
# Send ESC sequence to the POS printer via its queue:
echo -en 'ESC sequence' | lp -d 'POS_printer_queue' -o raw
# Have the input at fd0 (stdin) in any case:
[ -n "$6" ] && exec <"$6"
# Forward the actual print job data as is to the next stage:
cat -
-------------------------------------------------------------------
