Fax Console prints mirror images?

I have an HP L7780 Officejet all-in-one printer and I am running XP
Professional SP3.

I have Microsoft Fax Console (version 5.1) set to receive faxes
automatically, and to print them on receipt. However, all faxes are being
printed as mirror images.

The faxes appear correctly when viewed as onscreen images, and will print
correctly from Fax Console if I manually print them after their arrival. It
is just the automatic printing on receipt of faxes that is the problem.

All other print jobs are printed correctly.

Does anyone know how I can get Fax Console to print faxes correctly at the
time thay are received?

Thanks.
