ppdpo - ppd message catalog generator (deprecated) ppdpo [ -D name[=value] ] [ -I include-directory ] [ -o output-file ] source-file ppdpo extracts UI strings from PPDC source files and updates either a GNU gettext or macOS strings format message catalog source file for translation. This program is deprecated and will be removed in a future release of CUPS. ppdpo supports the following options:

5 -D name[=value] Sets the named variable for use in the source file. It is equivalent to using the #define directive in the source file.

5 -I include-directory Specifies an alternate include directory. Multiple -I options can be supplied to add additional directories.

5 -o output-file Specifies the output file. The supported extensions are .po or .po.gz for GNU gettext format message catalogs and .strings for macOS strings files.

PPD files are deprecated and will no longer be supported in a future feature release of CUPS. Printers that do not support IPP can be supported using applications such as ippeveprinter (1). ppdc (1), ppdhtml (1), ppdi (1), ppdmerge (1), ppdcfile(5), CUPS Online Help (http://localhost:631/help) Copyright \[co] 2007-2019 by Apple Inc.
