Constraint messages
Constraint messages are unsolicited messages that appear in response to specific actions you take. These messages
alert you to selections that are illogical or impossible given the capabilities of the printer or the current settings of other
controls. For example, if you click Print on Both Sides and then change the paper type to transparencies, a message
appears asking you to resolve this conflict.
Figure 34: A typical constraint message with an OK button
Whenever a constraint message appears with OK or Cancel buttons, the interpretation of the buttons 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, setting the control back to its previous value.
Layout tab
The Layout tab is a Microsoft-owned tab page that you can use to change the layout of printed pages. The Layout tab
is the default tab that appears when you click Document Defaults . . . (or Printing Preferences, depending on your
operating system) for the driver or for a software program.
The following group boxes are available on the Layout tab:
•
