[cups-devel] Saving all properties of a CUPS queue

[Till Kamppeter]

Thank you very much. I have implemented the saving and restoring from 
option settings in cups-browsed now (on BZR repo).

I do it as lpadmin does it. Create options and run it through 
cupsEncodeOptions2().

I take exactly these plus the PPD options (if the queue has a PPD), but 
I leave out printer-state, printer-state-message, printer-state-reasons 
(are set by CUPS and the user is supposed to read them, not to set 
them), port-monitor (causes problems and also does not really make sense 
to be set by the user), device-uri (cups-browsed already takes care of 
the device URI and the user is not supposed to change it). In the PPD 
options I skip PageRegion, as usual.
