The Printcap file controls these printer functions:  condensed mode
on/off, lines per inch (66/88 lines per page), characters per inch, and
backspace.

The functions are defined by the following two character control codes used
in the Printcap file:

   cn Condensed mode on
   cf Condensed mode off
   ld Line density
   bs Backspace
   pd Print density

Line density control uses an ASCII numeric value expressed in standard
typographic points (1 point=1/72 inch).  To determin the number of lines
per inch, divide the number of points by 72.  For example, setting ld72
would select 1 line per inch.  A value of ld12 would equal 66 lines per page
on 8.5" x 11" paper.

Print density uses an ASCII numeric value to express the number of
character to be presented per inch.  For example, pd6 would be equal to 6
characters per inch and pd1 would print 1 character per inch.

For sample Printcap files, see Appendix C of the SNA Gateway Administrator's
Guide.
