Unfortunately, there is some variation in the wording of these messages. This can cause problems for commentators which wish to recognize certain conditions and select appropriate sound clips or take other actions.
To solve this problem, PPR has two files which are used to look up an printer message and translate it to a standard wording.
The file /etc/ppr/lw_errors.conf contains those messages which begin with ``PrinterError:''. The file /etc/ppr/lw_status.conf contains those messages which do not.
Each file is divided into a number of sections, one for each message. The section is begun with a line which is the standard form of the message enclosed in square brackets. That is followed by all the various forms of the message, one to a line, enclosed in double quotes.
If pprdrv searches one of the files and does not find the message it is searching for it adds it to a new section at the end. This section has an empty name, expressed as ``[]''. These messages should be moved to the appropriate section.
