This is a simple client implementation of the CPNP protocol used by the
|
|
Canon Selphy CP-900 printer, and possibly others. I'm not aware of any
|
|
protocol spec being available, but it was pretty simple to reverse-
|
|
engineer.
|
|
|
|
The protocol is fairly similar to the BJNP protocol used by normal Canon
|
|
printers. I've peeked at http://sourceforge.net/projects/cups-bjnp/ here
|
|
and there for hints and ideas.

INSTALL & USAGE
|
|
===============
|
|
|
|
This should be pretty simple. Just build it, there are no special
|
|
dependencies other than a Go compiler, obviously.
|
|
|
|
See --help for available flags. You can use --printer_ip/_mac to specify the
|
|
printer to send your job to. By default, the tool will send a discovery
|
|
packet to 255.255.255.255 and send the job to whichever printer responds
|
|
first (and since regular non-photo printers speak a slightly different
|
|
protocol, that's often going to be just fine). If you're trying to send a
|
|
job to a printer not on your local network/broadcast domain, you can use
|
|
--printer_ip.
|
|
|
|
The program is pretty spammy at runtime, I haven't really tried cleaning
|
|
it up yet. Also, I haven't been able to use it much yet, so maybe it won't
|
|
work for you at all.
