A lesson site for the lab (session cookie, one-time addresses, a second
origin, a request log) and real right-clicks on its words and on a JPEG, a
PNG, a transparent PNG, a one-time picture, another site's, a blob:, a
WebP, a canvas, a linked picture, a broken one, and Cancel. Each is judged
on the job CUPS kept — where and how large, no other ink — and on the site
log: nothing was fetched again. The clipboard is the teacher's afterwards.
Black and white: a colourful lesson turned back and forth five times on
page 2, a worksheet, a picture at 50% top left, a page full of pictures,
back to Color, and Cancel. Every grey preview is grey pixel for pixel and
the job is byte-for-byte the file shown, through pxlmono. The three 0.2.6.2
black-and-white scenarios now wait for the grey file before Print, as a
teacher has to. 343 checks, none failing.

The black bars above and below a printed picture were neither in the
picture nor in the layout. A PNG or JPEG in a tab of its own is shown by
the engine on a viewer page whose background is rgb(14, 14, 14), and Qt
prints page backgrounds by default; 0.2.6.1 printed that page.
A picture is now taken as itself — drawn onto white, capped at 300 dpi
across Letter — and laid out on the printer's paper by the preview, with
Size (as large as fits down to 25%), Position (nine squares), Paper
(automatic, upright, sideways) and Fill the whole page, which says it
cuts the edges off and is never the default. The preview is the PDF that
prints, laid out again after each change. Worksheet PDFs and lesson pages
get no picture controls and are unchanged.
Page backgrounds are no longer printed for lesson pages either, as in
Chrome; Blink darkens light text when it does that, so a white-on-black
page prints readable grey on white. "Colour" is "Color" in the print
interface and the manual.
Lab: 135 print checks, now including eight picture layouts measured on
the job file CUPS kept — byte-identical to the preview, within 1 point of
where asked, no ink anywhere else. Printed from the real session with the
pointer: 50% top left, Elmer-66, the same. Not yet on paper.
