Lexmark Printer User Manual page 322

Type
File types that can be stored on flash memory or disk have unique extensions. The
following file types are recognized by the flash format used on earlier printer models;
the name of the file type printed in the directory appears in parenthesis.
.t1 (PostScript font)
.sFnt5 (PCL scalable font)
.bFnt5 (PCL bitmap font)
.Mac5 (PCL macro)
Except as noted below, file types listed above are recognized by the flash format used
in your printer. In addition, the flash format in your printer also recognizes the following
formats:
.data (user data) - any file written with PostScript operators
.type1 (PostScript font) - replaces the earlier .t1 extension
.demo (demo) - used for demonstration printouts or forms
.p5scalable (PCL scalable font)
.p5bitmap (PCL bitmapped font)
.p5macro (PCL macro) - replaces the earlier .Mac5 extension
.p5symset (PCL symbol set)
Usually the PostScript file operators can only read/write files with the extension .data.
Use the setfilenameextend operator to read/write other file types, including .demo.
Any other file type appears in the list as Unknown File Type. The description column
then contains the full filename with the file type (extension).
Size
The size listed for each resource includes the size of the file header.
Prot.
