redhat-config-printer and PPD files

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



One thing I'd like to get done for Fedora Core 2 is the ability for
redhat-config-printer to accept a manufacturer's PPD file and just use
it.  It is incredibly easy to configure CUPS for this.

The trouble is that redhat-config-printer doesn't just configure CUPS,
it manipulates an alchemist database and then a different program
writes the alchemist data out as CUPS configuration files.

The original reason for using alchemist is, I think, no longer valid.
The idea was that it would be nice to be able to 'roll out' a printer
configuration to a whole lot of computers.  CUPS browsing makes this
redundant IMHO (I'd love to hear opinions on that).

Ideally we could just dump alchemist and let redhat-config-printer
configure CUPS directly.  Unfortunately that would mean re-writing a
lot of code -- in fact, just about all of it.

The alternative is to find a replacement for redhat-config-printer
that *does* configure CUPS directly, and there are several candidates
I think.  Whichever one is chosen would have to be adapted to be a
drop-in replacement.  Kudzu likes to be able to automatically
configure print queues, for instance, and it would be nice not to make
the graphical interface any worse.  And of course the text mode
interface would most likely disappear altogether.

In the mean time, I could just add support for vendor PPDs in
redhat-config-printer by just bypassing alchemist altogether, in a
similar way to how it enables/disables cups-lpd (the tick-box just
runs chkconfig).  Good idea?

Opinions welcome.

Tim.
