FoomaticRIPCommandLine fails

[litauer]

I am using a ppd printer from ricoh (Ricoh IM C3010 PS) including the following FoomaticRIPCommandLine:

%%%%Title: (&title;)
%%
%%\n%A%B%C%D"%%%%; /bin/cat;"
*End

If &title; is substituted e.g. with "Antrag%20WM.pdf", the command line fails with: %20W invalid directive

I think the title is produced by a Webbrowser-PDF-Previewer on a Linux oder Mac-computer using cups as print system. The document title in fact is "Antrag WM.pdf".
