<!--
This test checks if content is paginated correctly in the horizontal
direction when printing . The test passes if the pages generated
are identical for both vertical - lr and horizontal - tb writing - modes by means of
making the size of the content we are printing equal to exactly the same number
of pages being generated in each writing mode .
This sizing is calculated like so :
1 . It is important to note that irrespective of the writing - mode , the print
UI always lays out printed pages vertically . Therefore , it is possible
to equate the printed content of two different writing modes if both
cases generate the exact same number of pages ( and of course no text on
the pages , which is why we use background color since it is independent
of writing mode ) .
2 . To avoid an unnecessary vertical scrollbar ( since scrolled content will be
clipped anyway in the reftest snapshot ) , the maximum number of 5 X3in pages
that we should generate for the reftest snapshot are equal to 3 .
3 . Considering a margin of 0 . 5 in on each side of the 5 X3in page , we get the
size of the page content area to be 4 X2in per page and to generate exactly 3
printed pages from this in the vertical - rl writing mode , we need a printable
area of 12 X2in ( as used below ) .
Similarly , the size for the reference printable area is calculated , only
considering a horizontal - tb writing mode .
It is important to note here that when printing this test outside of the test
harness , the background color will not show since we omit printing and
previewing of background colors by default via the browser printing path .
