# Sample configuration file## This file will be automatically read upon startup if it is placed in# /etc/pnm2ppa.conf## uncomment entries by removing "#" to activate them.##-----------set the printer model---------------------------# YOU MUST CHOOSE ONE OF THE FOLLOWING, EVEN IF YOU DO NOTHING ELSE!## If there is more than one "version" entry activated, the last one# will be used. The printer version can also be set with the command line# option e.g., "-v 720".#version 720 # 710, 712, 722 also acceptable#version 820#version 1000#--------control system log messages from pnm2ppa-------------------# pnm2ppa issues progress and error messages to the system log (syslog).# For security reasons, no input from the user is ever sent to the syslog.# The setting "silent 1" suppresses messages to the syslog. The# setting "verbose 1" sends messages to the standard error stream (stderr)# in addition to the syslog. (Note: on BeOS, syslog messages are# diverted to stderr; use "silent 1" to suppress them.)# Note: the "silent 1" keyword is only accepted from the system# configuration file (/etc/pnm2ppa.conf), and not from configuration files# specified with the pnm2ppa option "-f".#silent 1#verbose 1#---------set the margins of the printed page-------------------# Margins: these are distances from the edges of the paper in# "dots" ( 600 dots = 1 inch = 2.54 cm).# Nothing outside these margins will be printed.# Default values are give below; uncomment and change, if necessary.# (Older versions of pnm2ppa required larger left and right margins to avoid# printer failure with "flashing lights", but this problem is believed to# be solved)#topmargin 10#bottommargin 150#leftmargin 10#rightmargin 10#----------center the printer output on the paper-------------------# Offsets: these are adjustments for centering the print correctly on the# paper. Units are dots (1/600 inch). Add a positive number of dots to# xoff to move the printed image to the right, relative to the paper.# add to yoff to move it down. The helper program calibrate_ppa prints# a test page to check the offsets (see CALIBRATON.txt):# usage: "calibrate_ppa --center | pnm2ppa --bw - - | lpr -l# Default values are:#xoffset 160#yoffset 50#------------align the black and color ink cartridges--------# Color Offsets: these control alignment between the black ink# and color ink print cartridges. This changes a little whenever you# replace an ink cartridge, so the default values are just approximate.## Use "calibrate_ppa --align | pnm2ppa --fd - - | lpr -l "# to print a test page to help you adjust the color offsets.## The first line checks horizontal alignment ColOffsX,:# The second line checks vertical alignment ColOffsY,:# The alignment is correct if alignment patterns "0" is best.# If a diffent alignment pattern is best, add or subtract the + or# - value shown below it to ColOffsX or ColOffSy.## See CALIBRATION.txt for more details.# Use "calibrate_ppa --test | pnm2ppa --fd - - | lpr -l " to check your# new settings.#ColOffsX 0#ColOffsY 0#---------------"shearing" corrections-------------------------------------# shearing correction (for bidirectional printing modes)# if there is a horizontal offset between right-to-left and left-to-right# sweeps of the print head, adjust these in units of 1"/600 (1 dot).# There are separate corrections colorshear and blackshear for the# color and black print heads. The third and fourth lines of the# alignment test page (see above) tests these.# The setting is correct when alignments "0" are correct.# Add or subtract the + or - number shown under the best-aligned shearing# alignment pattern.#colorshear 0#blackshear 0#-------------blackness control-----------------------------# this controls the density of black ink used.# valid blackness choices are 1 2 3 4; controls the# density of black ink used: 1 (least ink), 2 (default), 4 (most).# 0 = no black ink. This affects black ink bordered by whitespace# only (e.g. text, but not black in color images)#blackness 2#------------Color correct curve Gamma parameters-------------------------# Gamma color correction values for Red, Green and Blue:# (Note: a more effective method of color correction is to use# a calibration file /etc/pnm2ppa.gamma, in which case these# Gamma values will not be used. See COLOR.html or COLOR.txt)# The pnm2ppa option --noGamma suppresses color correction.# The standard Gamma enhancement curve is# gEnh(i) = (int) ( pow ( (double) i / 256, Gamma ) * 256 )# (i.e., 256 times ( i*(1.0/256)) to the power Gamma ),# where (int) i is the ppm color intensity, in the range 0 - 255.# positive values of Gamma enhance (increase the intensity of)# the corresponding color. Gamma = 1.0 corresponds to no# color correction, gEnh[i] = i.# You can specify Gamma values as a decimal number for each primary color#GammaR 1.0 # red enhancement#GammaG 1.0 # green enhancement#GammaB 1.0 # blue enhancement# For use with the printed output of "pnm2ppa -g ",# you can also specify Gamma values using the integer GammaIdx,# which gives Gamma = 1.0 - 0.033 * GammaIdx :#RedGammaIdx 0#GreenGammaIdx 0#BlueGammaIdx 0# Default papersize (only used for printing the color calibration# test page with pnm2ppa -g).# Valid choices are: a4, letter, legal:#papersize letter # this is the default#papersize legal#papersize a4#-----------suppress bidirectional printing---------------------# by default the printing sweeps are now bidirectional (unimode 0);# to make unidirectional printing (left-to-right) the default behavior,# (unimode 1) uncomment the next line . (The command line options --uni# and --bi override the default behavior).
