I have a mac mini to which my printers are connected.  This runs CUPS v1.1.20.  By and large printing works just fine: all the remote printers are detected and I can print documents.  However opening of the print dialog is painfully slow when using KDE applications (much more responsive when using OOO or firefox).

Some debugging on the server indicates that it is sending the PPD of each printer, twice, to the KDE client before the print dialog is even drawn.  By comparison the PPD of only the default printer is sent to non-kde applications.  As there seems to be some slowness about this file transfer this seems to explain the relative slowness of KDE printing.

Note also that the KDE print dialog seems to download the PPD again when the a new printer is selected via the pull-down on the print dialog.  Even though that ppd will already have been downloaded at least twice already.

All in all KDE needs to be a lot smarter about caching this information in order to provide a responsive remote printer interface.

Thanks.
