class printer-dc% : class?
superclass: object%
extends: | dc<%>

A printer-dc% object is a printer device context. 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.

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.

> constructor (new printer-dc% [[parent parent]]) → (is-a?/c printer-dc%)
> parent : (or/c (is-a?/c frame%) (is-a?/c dialog%) #f) = #f

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