Pagination and Layout Model

PrintingTools separates document construction from pagination and output formatting.

Main building blocks

PrintDocument packages printable visuals or enumerators.
IPrintPaginator decides how pages are split and expanded.
PrintPage and PrintPageMetrics capture the actual page geometry.
PrintOptions controls margins, paper size, page ranges, and layout modes.

Layout modes

Standard
NUp
Booklet
Poster

Platform adapters consume the normalized layout metadata rather than inventing their own per-platform rules.

Layout hints

PrintLayoutHints lets you annotate visuals with printable metadata such as page breaks, page names, and layout-affecting hints. Those hints feed the default paginator and remain available to custom paginator implementations.

Page metrics

PrintPageMetrics normalizes:

logical page size
pixel page size
content rectangle after margins
content offsets used when a single visual expands to multiple pages

That shared model keeps preview thumbnails, vector export, and native print output aligned.
