thailpof - Generic filter for printing Thai text files
/usr/lbin/thailpof [-c] [-h host] [-H] [-i indent] [-l length] [-n login]
[-P printer_id] [-S] [-w width] [accounting_file]
-c Prints control characters.
Specifies the host name of the job owner. This name can contain Thai
-H Enables half-height printing mode. In printers without a one-pass
printing mode, Thai characters are printed on 3 levels, or 3 lines.
When half-height printing mode is enabled, the 3 levels are printed in
1.5 lines, which improves the appearance of output. The cost of this
improvement is slower printing speed.
Specifies the amount of indentation. The default value is no (no inden-
Specifies the page length in lines. The default value is 22.
Specifies the login name of the job owner. This name can contain Thai
Specifies the printer ID in the format that conforms to the Wototo
Specification. This format is [bb][mm][nn] where:
bb Is the brand ID, representing the brand of the printer.
mm Is the model ID, representing the model of the printer.
nn Is the code ID, specifying the character code used by the
-S Enables space-compensation mode. Many of the existing tools for text
alignment cannot handle nonspacing characters properly. When printing
output from such tools, enabling space-compensation mode improves
alignment of output text.
Specifies the page width in columns. The default value is 80.
Specifies the file to record accounting information.
The thailpof filter is a generic print filter for Thai text files. The
filter handles the device dependencies of printers and performs accounting
functions. At print job completion times, accounting records are written
to the file specified by the af field in /etc/printcap.
The filter can handle plain text files and files that have been prepro-
cessed by nroff. Either kind of file can contain Thai characters. The
thailpof filter translates nroff control sequences for underlining, super-
scripting, and subscripting into the proper control sequences for the
The thailpof filter can be the specified filter in both the of and the if
fields in the /etc/printcap file. For a description of these fields, see
To print Thai characters on the flag page using 3-pass mode, you must
specify /usr/lbin/thailpof in the of field of the /etc/printcap file. In
3-pass mode, however, the flag page is not printed on one page. Therefore,
if you do not plan to print Thai characters on the flag page, or if you are
using one-pass mode, do not specify /usr/lbin/thailpof in the of field.
The lpr command supports a number of options and associated arguments to
enable localization features supported by various printers. The following
can be used with the thailpof filter:
To specify one-and-a-half line printing
To enable space-compensation mode.
To specify the pathname of the character code table
For a complete description of this option and its associated arguments or
values, refer to lpr(1).
The lf field (default value is /dev/null) in the /etc/printcap file speci-
fies the name of the error log.
