Are you suggesting that I should be able to simply enable raw queuing with the Canon drivers for my printer? As far as I could tell, I have a choice - raw or Canon. With raw, localhost won't print (logs don't reveal a problem either), but with the Canon driver, I can print locally but not from Windows (logs complain that an octet stream arrived and it didn't know how to handle it).

When I went into the mime.types and mime.convs manually and uncommented the octet-stream line with the Canon drivers, then I could print both from localhost and from networked printers. But that, I've been told, is not really how I should be doing it -- aside from the fact if I change anything using the redhat-config-printer tool it'll re-create my mime.* files and comment the octet-stream line out again.

Thanks, Brion

Interesting. I have the raw octet stream enabled in mime.*, both windows and localmachine print perfectly.
