fontfile
    The HP LaserJet font file to convert.

The hpftodit command converts Hewlett-Packard (HP) LaserJet font files (typically with extensions like .pfa, .pfb, or .sfd) into a format suitable for use with the ditroff typesetting system.
Specifically, it generates a font description file that ditroff can understand, allowing you to use HP LaserJet fonts within your ditroff documents.
This is particularly useful when you want to produce high-quality printed output using fonts that are commonly available for HP printers but not natively supported by ditroff.

The command may not support all types of HP LaserJet fonts. Complex or highly specialized fonts might not be converted correctly.

The output file will generally be named using the font name derived from the input file (or as specified with the '-n' option) and placed in the specified directory (or the current directory if none is specified). The file contains the font description for ditroff to utilize the font.
