32 | .SH DESCRIPTION | |
33 | The CUPS filter interface provides a standard method for adding support for | |
34 | new document types to CUPS. Each filter is capable of converting from one | |
35 | or more input formats to another format that can either be printed directly | |
36 | or piped into another filter to get it to a printable format. | |
37 | .LP | |
38 | Filters must be capable of reading from a filename on the command-line | |
39 | or from the standard input, copying the standard input to a temporary | |
40 | file as required by the file format. All output must be sent to the | |
41 | standard output. | |
42 | .LP | |
43 | The command name (argv[0]) is set to the name of the destination printer. | |
