This lets users e.g. print-to-scale where it matters. Custom margins are still clamped to unwriteable margins, even when all zeroes, to avoid impacting user-specified & persisted margins. Differential Revision: https://phabricator.services.mozilla.com/D152900

* Duplex printing options.
|
|

|
|
* Note that other libraries refer to equivalent duplex settings using
|
|
* various sets of terminology. This can be confusing and inconsistent both
|
|
* 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.
