6 pnm2ppa - convert portable anymap (PNM) images to HP's PPA printer for‐
7 mat.
8
10 pnm2ppa [options] [ -i infile ] [ -o outfile ]
11
14 Reads portable anymap (PNM) format as input. Binary PNM formats pnmraw
15 = {ppmraw (color pixmap), pgmraw (graymap), and pbmraw (black-and-white
16 bitmap)} are strongly preferred. Output stream can be locally pro‐
17 cessed by Hewlett-Packard's Printing Performance Architecture (PPA)
18 printers (HP DeskJet 710C, 712C, 720C, 722C, 820C, and 1000C series).
19 (PNM format output can be produced from PostScript(tm) input by the
21 GhostScript output devices "pbmraw", "pgmraw" or "ppmraw", or by "pnm‐
22 raw", which will choose one of these formats as appropriate for the
23 document.)
24
26 -b bottommargin
27 Sets the bottom margin bottommargin in units of 1/600 inches
28 (e.g., -b 150 corresponds to 0.25").
29 -B blackness
32 Sets the black ink density blackness in drops per pixel
33 (0,1,2,3,4).
34 --bi Force bidirectional print sweeps.
37 --bw Disables the color cartridge; will print in grey scale using
40 only the black cartridge.
41 -d Displays the current configuration.
44 --eco Econofast mode: lower print quality that is faster and saves
47 ink.
48 -f configFile
51 Re-reads configuration from configFile (after initially reading
52 it from /etc/pnm2ppa.conf).
53 -F GammaFile
56 Overrides reading the color-correction table (Gamma curve) from
57 the default file /etc/pnm2ppa.gamma, and uses GammaFile instead.
58 --fd Enable fast ordered dithering instead of using the slower, but
61 beautiful, Floyd-Steinberg dithering. (Has no effect in --bw
62 mode.)
63 -g Prints a page of color intensity samples (for comparison with
66 gamma.ppm data produced by calibrate_ppa). This is part of a
67 color-correction procedure; see COLOR.txt for more details.
68 -h, --help
71 Displays program usage.
72 -i infile
75 Input file infile is either a path to a PPM file, or '-' to
76 indicate stdin (defaults to stdin).
77 -l leftmargin
80 Sets the left margin leftmargin in units of 1/600 inches (e.g.,
81 -l 150 corresponds to 0.25").
82 --noGamma
85 Switches off any color-correction.
86 -o outfile | -
89 Output file outfile is either a path to a file or device, or '-'
90 to indicate stdout (defaults to stdout).
91 -p Disables the black ink cartridge; i.e., print using only the
94 color ink cartridge, even for printing "black". This might be
95 useful for printing high-quality color images.
96 -r rightmargin
99 Sets the right margin rightmargin in units of 1/600 inches
100 (e.g., -r 150 corresponds to 0.25").
101 -s papersize
104 Sets the default paper size (now used only for color-correction
105 output produced by the -g option). In normal use, pnm2ppa now
106 instead reads the paper dimensions from pnm input file headers,
107 and checks that it is a valid papersize for the given printer
108 model. Possible values for papersize are a4 (A4), letter or us
109 (US Letter, 8.5"x11"), legal (US Legal, 8.5"x14"). The default
110 is US Letter.
111 -t topmargin
114 Sets the top margin topmargin in units of 1/600 inches (ie -t
115 150 corresponds to 0.25").
116 --uni Force unidirectional (left to right) print sweeps. Useful if
119 "shearing" is a problem for high quality color images.
120 -v printertype
123 Selects the printer model. Possible values of printertype are:
124 710, 712, 720, 722, 820 and 1000. The default is the HP DeskJet
125 7X0 Series (710, 712, 720, 722).
126 --verbose
129 Displays the program's System Log messages on the standard out‐
130 put, as well.
131 --version
134 Displays the program's version information.
135 -x xoffset
138 Sets the x-offset xoffset from the left of the page. Units are
139 1/600 inches.
140 -y yoffset
143 Sets the y-offset yoffset from the top of the page. Units are
144 1/600 inches.
145
149 The default configuration file /etc/pnm2ppa.conf is read in first.
150 Command line arguments then modify the resulting definitions.
151 The -v option resets all definitions (margins, offsets, etc.) back to
153 the inbuilt defaults for that printer and should be used before subse‐
154 quent -b, -l, -r, -t, -x and -y arguments.
155
157 pnm(5), ppm(5), pbm(5)
158
161 /etc/pnm2ppa.conf
162 Default configuration file.
163 /etc/pnm2ppa.gamma
166 Default Gamma (color-correction) file.

182 This program was originally pbm2ppa, written by Tim Norman. It origi‐
183 nally supported black and white output on the 820 series. Tim added
184 nascent color support in early 1999. In May 1999, Giorgio Marzano
185 started making real headway in getting color support working properly.
186 Andrew van der Stock has maintained the code since September 1999, and
187 made it available at http://sourceforge.net/projects/pnm2ppa.

190 Faint horizontal lines marking boundaries between print sweeps may be
191 visible. For best results when printing images, use the options -p
192 --uni .
