Installation of pnm2ppa  with S.u.S.E. Linux
------------------------------------------------------

1. Installation of program package pnm2ppa


Follow the standard installation instructions in INSTALL and CALIBRATION.  
The driver pnm2ppa is installed to /usr/local/bin. The manual page
pnm2ppa.1 is installed in /usr/local/man/man1. 

2. To integrate pnm2ppa into the BSD print spooler of the Linux system we 
create   printer spoolers in /etc/printcap, to print 
postscript files in color or black and white, and to print plain ascii files.

See the file README.lpd in the  subdirectory "lpd" of the pnm2ppa 
distribution.   This shows how to set up five printer descriptions: 

coloreco (normal quality color,the default);
color    (high quality color)
bweco    (economy mode black)
bw       (high quality black and white)
ascii    (for printing text files using enscript)


(Maybe there is a better way, using SUSE's own printing configuration
system; if so please let us know).

3. Now you are ready to print files with

# lpr filename.ps

which is equivalent to: 

#lpr -P coloreco filename.ps 

or explicitly specify the color and quality mode:

#lpr -P bweco filename.ps 
#lpr -P bw filename.ps 
#lpr -P coloreco filename.ps 
#lpr -P color filename.ps 

and for ascii (text) files:

# lpr -P ascii filename
