View > Show Print Tiling (view.printTiling) draws the pages of the document's print settings on the canvas, dashed and numbered, from print.preview's own layout (print.tiling), so the canvas and the printed job agree. The Print Tiling tool replaces the no-op tool: a drag places the first page's imageable corner (print.tiling.set, saved as print_setup.tileOrigin, one undo step); a double click on the canvas or the tool button resets it. Tiles start at the origin and extend to cover the art; the Print dialog shows the tool's placement with a Reset button. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
