`Pp.pcl`

Convert .phs output for a Hewlett-Packard PCL compatible printer

Syntax:

Pp.pcl [-1] [-A] [-b size] [-c colors] [-D debug_fname]
       [-d] [-L] [-ocn] [-odn] [-of] [-ogn] [-oh]
       [-omn] [-opn] [-orn] [-oSX,Y] [-osn] [-oyn] 
       [-U file] [-V]
       filename

Options:

-1

Invert black and white colors.

-A

Force anti-aliasing of fonts.

-b size

Specify size of printer buffer in bytes.

-c colors

Force size of color palette.

-D debug_fname

Send debug information to the specified file.

-d

Delete input file after processing.

-L

Enable landscape mode.

-ocn

Adjust cyan gamma correction (where negative is lighter, positive is darker).

-odn

Set printer graphical depletion (default: 1). Ranges between 0 (disables) and 5 (remove every fifth pixel).

-of

Enable Floyd-Steinberg dithering (the default).

-ogn

Adjust black gamma correction (where negative is lighter, positive is darker).

-oh

Enable halftone dithering (default: "-of").

-omn

Adjust magenta gamma correction (where negative is lighter, positive is darker).

-opn

Specify printing type. Choices are: 1 (B/W), 3 (CMY color), 4 (CMYK).

-orn

Set resolution (default: 300 DPI). Valid choices are: 75, 150, 300, 600.

-oSX,Y

Set scale in the X or Y dimension (e.g. -oS0.75,0.6), where scale value may be:

negative: scale as a multiple of the source image size
positive: scale as a multiple of the page size
0: maximum size while respecting the aspect ratio

-osn

Specify multiple pass printing "shingling" (default: 1). Valid range is between 0 and 2 passes.

-oyn

Adjust yellow gamma correction (where negative is lighter, positive is darker).

-U file

Delete this file when the print job is completed. Use for synchronizing print-spooling operations.

-V

Be verbose (-VV: be more verbose).

filename

Name of a Photon draw-stream (*.phs) file.

Description:

This utility converts .phs output for Hewlett-Packard PCL compatible printers. The Pp.pcl driver is usually used as a part of lpsrvr or called directly from the prsetup configuration.

Hewlett-Packard suggests the following settings:

Paper Type	Shingling	Depletion
Plain paper (Fast)	`0` (none)	`5` (50% with gamma correction)
Plain paper (Normal)	`1` (50%)	`1` (25%)
Plain paper (Better)	`2` (25%)	`4` (25% with gamma correction)
Plain paper (Best)	`2` (25%)	`5` (50% with gamma correction)
HP glossy paper (Normal)	`2` (25%)	`1` (25%)
HP glossy paper (Best)	`0` (0%)	`1` (25%)
Black transparency film	`2` (25%)	`0` (No depletion)
Color transparency film (Normal)	`1` (50%)	`1` (25%)
Color transparency film (Best)	`2` (25%)	`0` (No depletion)

Examples:

Pp.pcl file.phs >/dev/par

Files:

The output is sent to stdout. Typically this is redirected to a printer device, as shown in the example.
