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]
Prints control characters. Specifies the host name of the job owner. This name can contain Thai characters. 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 indentation). Specifies the page length in lines. The default value is 22. Specifies the login name of the job owner. This name can contain Thai characters. Specifies the printer ID in the format that conforms to the Wototo Specification. This format is [bb][mm][nn] where: Is the brand ID, representing the brand of the printer. Is the model ID, representing the model of the printer. Is the code ID, specifying the character code used by the printer. 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 preprocessed by nroff. Either kind of file can contain Thai characters. The thailpof filter translates nroff control sequences for underlining, superscripting, and subscripting into the proper control sequences for the printer.
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 printcap(4).
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 flags and associated options 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 flag and its associated options or values, refer to lpr(1).
The lf field (default value is /dev/null) in the /etc/printcap file specifies the name of the error log.
