Apparently my "enscript -2r" problem in FC5 was caused by the default paper size being set to A4 in GNOME instead of Letter. To fix this, type printconf-gui, enter root password, select printer, click Edit, select "Driver Options", change "Page Size" to Letter, click OK, click Apply. Repeat for each printer. It seems the default paper size should be set more accurately based on the user's location information during FC5 installation. Or, simply ask the user for a preferred default paper size. Of course, the OS should also be able to ask printers if a given paper size is loaded and available.
