Action 41: proposed text for new 3.10.x

ACTION-41 [1]: Draft a proposal for printing including the 3 concepts
--do not lose information, honor author print css, scale font size of
print

Draft a proposal for printing including the 3 concepts --do not lose
information, honor author print css, scale font size of print [1].


Proposed:

3.10.x Print Viewport (Level AA)

When the content of any viewport is rendered to a print viewport
(e.g., physical piece of paper) (Level AA):

 (a) all visual information present in the originating viewport is retained, and

 (b) authored CSS print properties are honored, and

 (c) the user has the option to scale and reflow the original content
to maintain readability of content that would otherwise exceed the
physical print page dimensions if rendered exactly as displayed on
screen.

Intent of Success Criterion 3.10.x:

When a user chooses to render Web content to a print viewport, there
should be no loss of visual information in the printed rendering. If
the author specifies CSS Print properties for the content, those
properties will be honored when the content is rendered to the printed
page. The user may increase the font size of Web content to improve
readability and has the option to scale and reflow the content on the
resulting printed page.

Examples of Success Criterion 3.10.x :

A user with low vision is reading an online newspaper with the
assistance of a screen magnifier and wishes to make a print copy of an
article so that they may continue reading while on the commuter train.
The user selects the large print option on their browser's print
dialog to create an easy to read print version. The resulting print
version uses increases the default font size to 16pts and reflows the
content so that it fits the page width.

Notes:

1. Guideline 3.10 requires renumbering.  This proposal should become 3.10.12

2. For 3.10.x, I do not specifically reference font size. With
Guideline 3.6 covering text configuration, I do not think it is
necessary to repeat that here, though others may feel differently.

3. Thanks to Jim for helping restart this.
