Files contain different character sets and data types.
  Each data type has a unique format. The Print Format
  list box allows you to describe what kind of data is in
  the file. DECwindows then interprets that data, formats
  the data, and prints the file.

  A highlighted format in the Print Format box is the
  default format unless you change it. The following
  formats are available in the Print Format box:

  Format Name  Data Type          Data Translation
