+ * Duplex printing options.

+ * Note that other libraries refer to equivalent duplex settings using

+ * with other libraries, and with the behavior that these terms intend to describe.
+ *
+ * kDuplexNone is equivalent to Simplex. Thankfully, both of these terms are
+ * consistent with the behavior that they describe, which is to have single-sided
+ * printing per sheet.
+ *
+ * kDuplexFlipOnLongEdge is equivalent to the following platform-specific constants:
+ * CUPS/macOS: NoTumble
+ * Windows: DMDUP_VERTICAL
+ * GTK: GTK_PRINT_DUPLEX_HORIZONTAL
+ *
+ * kDuplexFlipOnShortEdge is equivalent to the following platform-specific constants:
+ * CUPS/macOS: Tumble
+ * Windows: DMDUP_HORIZONTAL
+ * GTK: GTK_PRINT_DUPLEX_VERTICAL
+ *
+ *
+ * Notice that the GTK and Windows constants have opposite meanings for
+ * VERTICAL and HORIZONTAL.
+ *
+ * To make matters more confusing, these platform-specific terms describe different
+ * behavior (from the user's perspective) depending on whether the sheet is in
+ * portrait vs. landscape orientation.
+ *
+ * For example, the generic term "tumble" describes behavior where a sheet flips over
+ * a binding on the top edge (like a calendar). This requires that the back side of
+ * the sheet is printed upside down with respect to the front side of the sheet,
+ * so that its content appears upright to the reader when they tumble-flip the
+ * sheet over the top-edge binding.
+ *
+ * However, the CUPS/macOS Tumble setting only inverts the back side of the
+ * sheet in portrait orientation. When you switch to landscape orientation, the
+ * Tumble setting behaves like a book-like sheet flip, where the front and back
+ * sides of the sheet are both printed upright with respect to each other.
+ *
+ * This is why it is more consistent and more clear to think of these terms
+ * with regard to sheets being bound on the long edge or the short edge.
+ *
+ * kDuplexFlipOnLongEdge + Portrait = book-like flip (front/back same direction)
+ * kDuplexFlipOnLongEdge + Landscape = calendar-like flip (front/back inverted)
+ *
+ * kDuplexFlipOnShortEdge + Portrait = calendar-like flip (front/back inverted)
+ * kDuplexFlipOnShortEdge + Landscape = book-like flip (front/back same direction)
+ *
+ * The long-edge and short-edge terminology unfortunately breaks down when printing
+ * with square sheet dimensions. Thankfully this edge case (hah) is quite uncommon,
+ * since most standard printing paper dimensions are not square. Such a paper size
+ * would even break the uniformly used portrait and landscape terminology.
