[Openicc] colord Printing Plans

[Till Kamppeter]

Looks nice, but there is one question:

What happens if the application from which the job is sent and the 
printer are not on the same machine or not even on the same local 
network. CUPS has all capabilities for networked printing, even through 
the internet. Does this mechanism also work in such a situation? Is it 
really needed to have an extra daemon? Is it not possible to do 
everything with CUPS (perhaps with patches to CUPS)?

Do have made the code of pdftoraster and pstoraster available somewhere? 
pstoraster is perhaps even not needed as due to the nature of 
Ghostscript accepting both PDF and PostScript as input probably 
pdftoraster also accepts PostScript and does the right thing with it.

About Foomatic, you do not need to be an expert in Perl. Programming 
languages are not that different. In case of questions simply ask me. 
And the part which is probably the most important for you, foomatic-rip, 
is already converted to C from version 4.0.0 on.
