That wiki page is somewhat outdated. In the end, it really depends on how the integration can be best handled. The goal should be that CPD support is transparent to the user of Qt, similar to how the native print or file dialogs work on other platforms. But the native print dialogs do currently all live inside Qt print support, so I don’t see why we shouldn’t add one more. > >> Just to summarize briefly, implementing CPD support directly in the >> print dialog would mean that the Qt team wouldn't have to worry about >> any future CUPS changes, or any other print backends for that matter, as >> CPD will handle them all instead. I am unsure whether we can get rid of CUPS and replace it with CPD, or whether we will need both side by side (and select the supported one at runtime). What’s the status here, are all Linux distributions nowadays supporting CPD? If yes, then we can either remove CUPS, or at least turn it into a compile time configuration option. >> >> It would be really helpful if you could share your views on this and >> give your suggestions. > > Whatever path you end up taking, I wish you good luck and a successful > project! Good luck with this, it would be great to see finally have CPD support for Qt.
