compression=gzip and RAW Print Queues (ipp)

[Andy Powell]

How do I get CUPS to decompress compressed data for Raw printers?

In the main office, I have ipp://remote.mydomain.com:631/printers/jaxshop?compression=gzip which is just a raw print queue.

And in the remote office, I have socket://jaxshop.mydomain.com:9100

When set to Raw, the compressed data is sent directly to the printer (it is not decompressed) and comes out as garbage.  If it is set to the printer definition, (e.g. HP LaserJet) it decompresses but this can't be done in some cases (e.g. HP/GL and Calcomp plotters).

Anyone know of a fix/workaround?
