+   that we should generate for the reftest snapshot are equal to 3.
+3. Considering a margin of 0.5in on each side of the 5X3in page, we get the
+   size of the page content area to be 4X2in per page and to generate exactly 3
+   printed pages from this in horizontal-tb writing mode, we need a printable

+
+It is important to note here that when printing this test outside of the test
