I was not able to determine how to work with your printing system appropriately.

You will therefore only be able to export your data to a PostScript file.

Please have your administrator verify if a descent printing system is installed.

If this is so, there must be a bug in ghfaxviewer. Please fill a bug report accordingly and send it to halifax-bugs@gnu.org.
