       This  program,  _p_._p_p_m,  reads  a  user-specified  portable
       pixmap (ppm) file and outputs it to the currently selected
       printer (see _p_._s_e_l_e_c_t).	The _i_n_p_u_t ppm file should be  one
       that has been created using the PPM utilities developed by
       Jeff Poskanzer.	These utilities can import various  image
       formats (including Sun raster, X Windows pixmaps, and oth-
       ers) into the PPM formats _p_p_m (color pixmaps),  _p_g_m  (grey
       scale maps), and _p_b_m (black and white bit-maps).


       If  the	image doesn't fit the output device, it won't get
       printed.  If you want the image printed (but clipped), use
       the pp..ppppmm --ff option, or scale the input using _p_p_m_s_c_a_l_e, or
       rotate the image using _p_p_m_r_o_t_a_t_e (if it will fit that  way
       --  otherwise you might have to scale it as well).  If the
       image doesn't fit, _p_._p_p_m will tell you what scaling  value
       to enter to _p_p_m_s_c_a_l_e that will make it fit.



EEXXAAMMPPLLEESS
       If  the	user  is running GRASS under SunOS, the following
       command could be used to send a monitor	screen	image  to
       the printer:


       ssccrreeeenndduummpp || rraassttttooppppmm || pp..ppppmm





       If you are running suntools, the user might type:


       sslleeeepp 1100;; ssccrreeeenndduummpp || rraassttttooppppmm || ppppmmrroottaattee 9900 || pp..ppppmm



       The  UNIX  _s_l_e_e_p  command  allows  you time to arrange the
       frames before the screen dump starts.   The  _p_p_m_r_o_t_a_t_e  is
       usually needed because the Sun screens are wider than they
       are long (and wider than 1024 pixels - which is the  width
       of most of our printers).


       If you are running X, the user might type:


       xxwwdd || xxwwddttooppppmm || ppppmmrroottaattee 9900 || pp..ppppmm


NNOOTTEESS
       This program only supports the ppm binary format (P6).


       Maximum	color  level  is  255.	 If the ppm file has more
       color levels, use _p_p_m_c_s_c_a_l_e to reduce the number  of  col-
       ors.


       No scaling is done.  Use _p_p_m_s_c_a_l_e to change image size.


       No rotation is done.  Use _p_p_m_r_o_t_a_t_e to rotate the image.
