While the filter interface is compatible with System V interface scripts, CUPS does not support System V interface scripts.

-CUPS filters are not meant to be run directly by the user.
+CUPS printer drivers and backends 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
+<b>ippeveprinter</b>(1).
+<p>CUPS filters are not meant to be run directly by the user.
Aside from the legacy System V interface issues (<i>argv[0]</i> is the printer name), CUPS filters also expect specific environment variables and file descriptors, and typically run in a user session that (on macOS) has additional restrictions that affect how it runs.
Unless you are a developer and know what you are doing, please do not run filters directly.
Instead, use the
-<a href="man-cupsfilter.html?TOPIC=Man+Pages"><b>cupsfilter</b>(8)</a>
+<b>cupsfilter</b>(8)
program to use the appropriate filters to do the conversions you need.
