format-not-supported

[cups-wg at magro-soft.com]

Hi,

occasionally I'm printing an acsii-file containing some non-ascii characters, like \030 and/or \033.
This results into error <client-error-document-format-not-supported>.

How can I insert a filter to cups to translate the non-ascii, lets say to a circumflex?
Or can I just simply make cups to ignore those non-asciit?

Version in use: CUPS-1.1.18

Thanks 4 help and hints
