Command-line options to specify print job set-ups (/PDFOPTS, /PCLOPTS, /PSOPTS) often include one or more parameters. When saving options you may choose whether mnemonic (alphabetic) or numeric parameters are used. The default format (for backwards compatibility) is numeric unless all options have been read in mnemonic form.

"Print formats" are those which include the text of the document as strings of characters (e.g. PCL, PDF, PS) rather than just images (e.g. JPEG, PNG, TIFF).
