How to make rwclient pass "Copies parameter value" to rwlpr.sh

We have various Barcode font files, we were able to implement printing them on reports by customizing "rwlpr.sh" (on Linux)

Internally "rwclient" is calling "rwlpr.sh" and "rwlpr" is issuing final print command after merging font file
to the report output file that was passed by "rwclient".

If we want want to print mutiple copies of the same report and pass the copies parameter.

rwclient is building one massive output file with muliple copies in it and then calling rwlpr.sh
with no copies parameter, rwlpr is taking defualt value for copies as 1.
due to the file size, print job is slowing down so badly.
