* Print: read lpstat untranslated so printers show on non-English macOS On a Mac whose interface language isn't English, the Print dialog listed no printers. `lpstat -p -d` follows the UI language (here Polish: "drukarka … jest bezczynna", "domyślny cel systemowy: …"), and parse_lpstat only knows the English "printer " and "system default destination:" prefixes, so it matched nothing. - lpstat now runs with LC_ALL=C and LANG=C, which is enough on Linux. macOS CUPS ignores both and follows AppleLanguages unless SOFTWARE is set, in which case it uses LANG, so SOFTWARE is set too. - New test: localized output parses to nothing, and the command sets all three variables. Checked on macOS with a Polish UI: only SOFTWARE=1 LANG=C gives English output, and the dialog now lists every printer with the right default. lp's error messages stay localized; they are shown, never parsed.

Layer L4: printing (execution plan M10.5).
let pages = select_pages(count, Some("1-3, ii, 9-"), &labels, Subset::All, false)?;
let settings = Settings { pages, paper: PAPERS[0].1, layout: Layout::multiple(4), ..Default::default() };
let sheets = layout(&display_sizes, &settings)?; // geometry only (previews)
let pdf = impose(&doc, &settings)?; // the print-ready PDF
spool::submit(&pdf, &spool::Job { printer: None, copies: 2, ..Default::default() })?;
- Size: fit (to the sheet minus an 18 pt margin), actual size, shrink oversized, custom %; centred; auto orientation turns the sheet for landscape pages.
- Multiple: 2/4/6/9/16 (or any n) pages per sheet, horizontal/vertical (reversed) order, page borders, auto-rotation of pages that don't match the cell.
- Booklet: saddle-stitch imposition padded to a multiple of 4; both sides, front or back only; left or right binding.
- Poster: tile scale, overlap shared by neighbouring tiles, cut marks.
- Comments & forms: document, + markups, + stamps, or form fields only; annotations print only with their Print flag, drawn from their appearance streams (Algorithm 8.1).
Each source page becomes a Form XObject (its content wrapped in q/Q, plus the printable annotations); sheets place them with a clip. The result is a fresh, unencrypted, garbage-collected file (callers check the print permission).
spool talks to CUPS (lpstat -p -d, lp with copies, collation, duplex and monochrome
options). Other platforms report that printing to a printer isn't available yet; the
print-ready PDF can always be saved.
Not yet: Windows and web spoolers, print as image, poster labels, PostScript output, colour conversion for grayscale.
