6.19  printer-dc%

Implements: dc<%>

A printer-dc% object is a Windows or Mac OS X printer device context. The class cannot be instantiated under X (an exn:misc:unsupported exception is raised).

Under Mac OS X, a newly created printer-dc% object obtains orientation (portrait versus landspace) and scaling information from the current ps-setup% object, as determined by the current-ps-setup parameter. This information can be configured by the user through a dialog shown by get-page-setup-from-user.

Be sure to use the following methods to start/end drawing:

• start-doc

• start-page

• end-page

• end-doc

Attempts to use a drawing method outside of an active page raises an exception.

See also post-script-dc%.

When a printer-dc% object is created, the user gets platform-specific modal dialogs for configuring the output. If the user cancels the dialog, the ok? method of the object returns #f.

• (new printer-dc% [(parent _)]) -> printer-dc% object
     parent = #f : frame% or dialog% object or #f

  If parent is not #f, it is used as the parent window of the configuration dialog.
