printer-dc% : class?

superclass: object%

extends:  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 landscape) 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.

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 parent]]) → (is-a?/c printer-dc%)

parent   :   (or/c (is-a?/c frame%) (is-a?/c dialog%) false/c)       =   #f

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