Hosting notes for the models and workers, the platform parity text, the ocr.ocr-web parity entry (now citing the ported tests, with the known limits: the page runs the cleaning steps, the Verify screen re-reads on the page, ocrs only), and the roadmap logs.

# Hardware and platform parity
|
||
|
||
> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-10-12 · **Change:** minor (web OCR shipped: Web Workers with SIMD, checked in a browser; earlier: 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](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.**

|
||
| Printers | all, PostScript, printer properties | CUPS via craft-print | Windows PDF raster spooler via craft-print (#756, PR #847) | CUPS via craft-print | the browser's print dialog (every printer the system knows): sheets drawn by PdfCraft at 150–300 dpi; copies, two-sided and colour set there | `crates/print/README.md`, `crates/ui-egui/src/workflows/web_print.rs` |
|
||
| Scanners (TWAIN, WIA, ICA) | yes | none | none | none (SANE) | n/a | `ocr.scanner-acquire` planned |

## Revision history
|
||
|
||
| Date | Change | Summary |
|
||
|---|---|---|
|
||
| 2026-10-12 | minor | Web OCR (`ocr.ocr-web`) shipped after a browser check |
|
||
| 2026-10-12 | minor | Web platform row: OCR downloads its models on first use and reads in Web Workers with SIMD (`ocr.ocr-web`, partial); what's left is speed |
|
||
| 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) |
