Re: [opensuse] RFR: Printing From Browsers

Exactly.

In particular since CUPS exist, any application can get
the whole PPD file for a particular print queue (even for
remote print queues) from the cupsd and the PPD file
contains all necessary information about the capabilities
of the output device, in particular
- imageable area (the media size is wrong and useless!)
- color or monochrome
- resolution

And if the application likes to produce generic output
(i.e. output which is not specific for a particular printer)
it could use its own generic PPD file (also as fallback
if no CUPS is available - e.g. on a system with LPRng).


... the browser shouldn't be getting all the blame.

Not all the blame but almost all the blame.

In particular usual HTML text intermixed with usual images
could be printed perfectly.

I see only problems when there is dynamically changing
stuff in the HTML, e.g. sequences of images ("movies").
In this case I think that the HTML must somehow contain
information which one of the sequence of images is the
right one which should appear on a "fixed" printout
or provide an alternative fixed image for printout.
