* Gates: fix two clippy failures on main - ocr_ui: "Also recognize pages that already have text" used egui's own checkbox, which clippy.toml disallows (#1184 landed beside #1173); use widgets::checkbox like every other box. - camera_edges: Rust 1.97's manual_range_contains; the rewrite keeps the old answer for a NaN angle (false) with an is_finite check. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_019ojKsSCHWk2AuyDTFMHCd7 * M10: print from the web build through the browser's print dialog (gap 4) The web build had no printer: spool::submit refuses on wasm, so Print could only download the print-ready PDF. Now its Print dialog offers "Browser's print dialog" (the default there), which reaches every printer the operating system knows. - web_print: PdfCraft draws the print-ready PDF's sheets itself (engine Exporter), one sheet a frame since wasm has no threads: 300 dpi up to 100 sheets, 200 up to 300, 150 up to 1,000, at most 64 MP a sheet and 1 GiB of PNGs a job. The PNGs become blob URLs and print from a hidden srcdoc iframe, one sheet per page, margin 0. - Chromium prints every page at the default @page size, so a sheet of the paper's size turned sideways is rotated 90 degrees CCW onto it (as drivers do); other sizes get named @page rules. - Copies, two-sided and colour are greyed out (the browser's dialog sets them). If print() is refused (e.g. a sandboxed frame), the print-ready PDF downloads instead, with the reason. - pdfcraft-print stays free of web APIs; six new strings in all 20 catalogs (ATTRIBUTION hashes refreshed); docs and parity updated, gap 4 closed. Verified in headless Chromium against a trunk build: three sheets at 300 dpi, the landscape sheet turned, no blank trailing page, and the download fallback. Firefox and Safari not yet tried.

Hardware and platform parity
Last reviewed: 2026-10-10 · Last updated: 2026-10-11 · Change: minor (web printing through the browser's print dialog; earlier: shared craft-print spooler with passing Windows CI; Windows printers row and 1:1 touchpad scrolling, #756, #759) · Target: Adobe Acrobat Pro (Acrobat DC, continuous track 26.002.21931, macOS)
Each hardware feature Acrobat Pro uses, per platform, ours against Acrobat's. Acrobat runs on macOS and Windows (plus a limited web viewer/editor in Document Cloud); PdfCraft runs on macOS, Windows, Linux, FreeBSD and the web. Gaps ranked in gaps.md.
Hardware ≈ 35% ready, 25–50 h (additional to the features total; scanners, smart cards and printing are counted in their feature areas). Platforms ≈ 70% ready, 15–30 h.

Revision history
| Date | Change | Summary |
|---|---|---|
| 2026-10-11 | minor | Web printers row: printing through the browser's print dialog (gap 4 closed); Web platform row no longer lists printing |
| 2026-10-10 | major | Created from the code, vendor/README.md, .github/workflows/release.yml, the print crate's README and user issues |
| 2026-10-10 | minor | Windows printing shipped (#756): the Windows row's gap is closed; the web row keeps "printing" |
| 2026-10-11 | minor | Shared craft-print spooler; Windows preserves PDF sheet size/orientation and uses corrected duplex binding edges. Physical output remains a hardware check. |
| 2026-10-11 | minor | The Printers row's Windows cell still said none: now the Windows spooler (#756, PR #847). Touchpad scrolling 1:1 (#759, PR #868) |
