** data in the print file.  The following types are defined (an
** implementation may define additional values):
** 
**  p - PostScript data. The client will ensure that a valid
**      PostScript header is included.
**  d - Diablo 630 data.
**  x - Generic printable ASCII text. The client will have filtered
**      out all non-printable characters other than CR, LF, TAB,
**      BS and VT.
**  r - Raw print data. The client performs no filtering.
**  u - User-defined. Reserved for custom extensions. A vanilla
**      pcnfsd server will treat this as equivalent to "r"
** 
** If diablo data (type 'd') is specified, a formatting specification
** string will be appended. This has the form:
** 	ppnnnbbb
**         pp
** Pitch - 10, 12 or 15.

**              bbb
** The ``bold'' font to be used - encoded in the same way.  For example,
** the string ``nd10hrbcob'' specifies that the print data is in Diablo
** 630 format, it should be printed at 10 pitch, ``normal'' text should be
