35Accuracy
samples/LabelaryCompare renders the ZPL corpus samples/labelary/*.zpl and compares it pixel by pixel (2-dot tolerance) with printer-accurate Labelary references. LabelaryReferenceTests keeps every case at least at its current value.

The 15 weakest of 169 cases; 131 cases reach ≥ 0.99, 85 are pixel-identical (1.000). Full list: dotnet run --project samples/LabelaryCompare (offline against the stored references in tests/ZplCore.Tests/Reference/labelary).
The weakest cases concern edge cases such as clipping beyond the label length (ll-clip), ^GD orientation, ^GS symbols, MaxiCode modes, rotated fonts and the code page cases (^CI), where mainly the glyph shapes of the replacement fonts differ. QR codes (^BQ, model 2) are module-identical with the printer-accurate reference renderings – mode selection, version, error correction and mask, checked on more than 3,600 Labelary reference symbols. QR model 1 is printed as model 2. PDF417 (^B7) and MicroPDF417 (^BF) are codeword-identical with Labelary – compaction as on a Zebra printer, under ^CI28 Latin-1 bytes without ECI (characters above U+00FF are left out), as for ^BX, ^BO and ^BD. All symbols remain decodable; Labelary does not render ^BB and ^B4, so these are verified exclusively against bwip-js.
