[cups-devel] how to get the page info of a canceled job?

[Douglas Kosovic]

Hi,

Mike's suggestion of using the CUPS API is way better.

I just thought you wanted something to do some quick debugging of a cancelled job. I usually use 'less' and don't worry about the binary characters.

I also thought CUPS may not know the page count of a cancelled job as it would depend on where in the printing process it got cancelled. Having the original print file might be the only way in these cases. At my site CUPS was configured not to delete print files after they were submitted and use a cron job to delete old files after a few hours.


Cheers,
Doug
