Incompatible Options messages
Incompatible Options settings (constraint) messages are unsolicited messages that appear
in response to specific actions that you take. These messages alert you to selections that
are illogical or impossible given the capabilities of the product or the current settings of other
controls. For example, if you click Print on Both Sides and then change the media type to
Transparency, a message appears asking you to resolve this conflict.
Figure 3-1. A typical constraint message with an OK button
Whenever a constraint message appears with the OK or Cancel button, the interpretation of the
button is as follows:
● Clicking OK accepts the change that was just made, and the driver then resets the
conflicting control to a setting that is compatible with the new value.
● Clicking Cancel rejects the change that was just made, and the control returns to its
previous value.
