Configuration files store information about the printer. For
example: Storing printer information in a configuration file is done
as a convenience so that you don't need to type in this information
each time you use the bitmap_print
or file_print
procedures. When you use these procedures, you only need to provide
the pathname of the configuration file. | | | |  | NOTE: All parameters must be present and in the exact order
shown. If parameters are missing or incorrect an error will be issued
and formatter action will be terminated. | | | | |
The parameters in the configuration file are : - ENABLE STANDARD OUT
If TRUE,
output goes to standard out regardless of the printer device file
specified in the next parameter. If FALSE,
output goes to the special device file or file specified in the
next parameter. - PRINTER DEVICE
FILE
Specifies the special device file for the printer.
This parameter is read but ignored if standard out enable is TRUE. - PRINT METHOD
Specifies color, color2, primary (red, green, blue,
cyan, magenta, yellow, black, white), gray scale, or monochromatic
(black and white). This parameter has allowable values of: color, color2, primary, gray, grey, mono, and monochromatic. If PRINT METHOD
is color, each
pixel is converted to an appropriate color. If print method is color2, each pixel is converted
to an appropriate color plus a random noise increment value. If PRINT METHOD
is primary then
each pixel is converted to the nearest primary color. If PRINT METHOD
is gray (or grey), each RGB pixel is
converted to an appropriate gray scale value. If PRINT MODE
is mono (or monochromatic), each nonzero
value RGB pixel is rendered black. | | | | | NOTE: Monochromatic-only formatters map color to gray and primary to monochromatic. That is, the
appropriate monochromatic mode will automatically be chosen. | | | | |
- PIXEL EXPANSION
Indicates the expansion for each pixel on the bitmap
and ranges from 1 to 8. For example, to expand each pixel of the
bitmap to a 3×3 cell, the expansion is set to 3. - RESOLUTION
Indicates resolutions in dots/inch. This is printer
dependent. For example, the HP 3630A has an available graphics resolution
of 180 dots/inch, while the LaserJet and LaserJet Plus printers
have four resolutions as follows: Note that this parameter and the subsequent page_width and page_length parameters are
used to determine the output "page" for clipping purposes. - SEND RESOLUTION
If true, specifies that the graphics resolution
escape sequence will be sent to the output file (printer). If false,
no graphics resolution escape sequence will be sent. This parameter
should normally be set to true unless special circumstances exist
(such as spooling). - PRINT START
POSITION
If this parameter is "current",
raster graphics rows start at the current text cursor position.
If this parameter is "margin",
raster graphics rows start at the left graphics margin. When this
parameter is margin,
a formfeed is sent to the printer at the completion of the graphics
data transfer. If this parameter is current,
no formfeed is sent upon completion of the graphics data transfer.
Note that the current
parameter is only useful for printers (such as the LaserJet or SprintJet)
which implement this capability of PCL. - PAGE WIDTH
Specifies the width of the printable graphics area
on the page in inches. - PAGE LENGTH
Specifies the length of the printable graphics area
on the page in inches.
The symbol "#"
in configuration files starts a comment and is operative for the
remainder of the line. Configuration File Template | |
A configuration file template for color pcl printers is provided
as file[19]: 〈formatters〉/pcl/cfg.ctmplt |
This template contains values appropriate for the HP 3630A
printer. A configuration file template for monochromatic PCL printers
is provided as file: 〈formatters〉/pcl/cfg.template |
A following section details parameter values for supported
Hewlett-Packard printers which you may wish to refer to in deciding
values for particular fields of your configuration file. Note that
parameters are position sensitive. That is, each parameter is required
to be present in the form and order listed. Example Configuration File[20] #----------------------------------------------------------------
