Background

The PDF specification describes some options that may be included in documents to make printing easier when related to number of copies, paper size, scaling and duplex printing.

At least for me, this was useful in two scenarios:

  • At work, where we have a automated system for document generation. Users only have to press Ctrl+P and forget about which options are required for which documents.
  • In copyshops, where duplex printing and no scaling were features that not everybody seemed to understand (or to handle) properly.

This feature requires a fairly recent beta version. As the time of this writing, 2016.06.20 22:14 was the lastest released version, although it has been implemented for some time.

Duplex Printing

Duplex printing can be specified using the key option= from the \setupinteractionscreen command. (This option from the mentioned command allows multiple values. Except the number of copies, all other three print features are values for the option key.)

Possible values are:

  • page: enables single–sided printing (mandatory to disable duplex printing in a printer in which is set by default).
  • portrait enables portrait duplex printing (the paper long side is flipped).
  • landscape enables landscape duplex printing (the paper short side is flipped).

Print Scaling

It is possible to disable print scaling in the document with the fixed value in the key option= from the \setupinteractionscreen command.

This may be a useful setting for printing documents where no content is placed on the margin area. Adobe products may shrink the content to printing area, whether this is required or not. When the document has no content on the printer margins, resulting output will be smaller than it should.

Paper Size From PDF Document

Unless paper size is read from the PDF document, Adobe will use the default paper size (A4 in Europe and letter in America).

paper is the value for the option key that specifies the selection of paper size from the document.

As explained before \setupinteractionscreen[portrait, fixed, paper] would print duplex flipping the long side, no scaling and taking paper size from the PDF document.

Number of Copies

The number of copies is set with the copies key from \setupinteractionscreen.

Although the specification limits the number of copies to the maximum offered by the print dialog, Adobe limited the number to a maximum of five for security reasons.

Conformant PDF Readers

To the best of my knowledge, only Adobe (Reader or not) from version 9 supports this feature.

evince allows duplex options in its printing dialog, but it cannot read these from the PDF document. There is an open issue in poppler to implement this feature.
