Hylafax printing

RH8
Hylafax
Canon iR5000 printer.

Two copies of incoming faxes are printed. I need only one copy. Command line in FAXRCVD script to print is:
fax2ps $FILE | lpr -Pcanon-01
The question is: is there an option that I could add to this command line to force printing of just one copy. Canon’s properties are to print one copy by default. Thanks.
