In particular it references /usr/lib/texmf/dvips which is presumably where the dvips(1) configuration was once upon a time. It's certainly not there on my vanilla install boxes. Probably should be /etc/texmf/dvips.
However, someone somewhere seems to have packaged it with a useful manpage:
dviprint - dvipsR wrapper for LyX
dviprint [<dvips arguments>?
dviprint is a wrapper around dvips(1) that adjusts the destination file and printer arguments (-o and -P) to handle variations in install configurations (e. g., whether dvips sends its output directly to a printer or writes to a file). It is part of the Debian packaging of the LyX editor.
