Subject: Re: Printing in a user agent



In UAAG1, printing seems to have been handled by the definition of
viewport (which we have no changed in UAAG2 yet), which said:

"Viewports include windows, frames, PIECES OF PAPER, loudspeakers, and
virtual magnifying glasses."

...but then in almost every instance of "viewport" in the document,
replacing it with the words "piece of paper" doesn't make any sense.

So...I propose...

(1) We remove "pieces of paper" from the definition of "viewport"

and...

(2) Taking into account Jim's comments with a new success criteria for
"Guideline 3.11 Help user to use and orient within viewports":

SC: 3.11.X Print Scale: If a print from viewport feature is provided,
the user has the option of printing using the viewport's scale settings
such that the user agent should attempt to *passively reflow* the
content into the horizontal dimensions of paper. If passive reflow is
not possible, more than one sheet of paper will be required horizontally.


ED. NOTES:
- by *passively reflow* I mean the kind of reflow that happens when you
resize a window manually.
- do any languages favour horizontal over vertical paper flows?


Cheers,
Jan
