DeviceFontSubstitution Enumeration
Specifies whether device font substitution is enabled on a printer.
Assembly: ReachFramework (in ReachFramework.dll)
| Member name | Description | |
|---|---|---|
| Unknown | The feature (whose options are represented by this enumeration) is set to an option not defined in the Print Schema. | |
| Off | Device font substitution is disabled. | |
| On | Device font substitution is enabled. |
Printing is faster when only the text, not the font, is sent to the printer. Some printers have fonts that are permanently stored in their memory. These printers enable users to substitute a resident printer font for each font that is used by the printing application.
The values of this type are used primarily for these purposes:
As members of the DeviceFontSubstitutionCapability collection, a property of PrintCapabilities, they represent the printer capabilities.
As the value of the DeviceFontSubstitution property of a PrintTicket, they instruct the printer to enable or disable device font substitution for the print job.
The Unknown value is never used in properties of PrintCapabilities objects.
You should never set a PrintTicket property to Unknown. If some other PrintTicket producing application has created a PrintTicket document that sets the device font substitution feature to an unrecognized option (that is, an option that is not defined in the Print Schema), then a PrintTicket object in your application that is constructed with that document will have DeviceFontSubstitution::Unknown as the value of the DeviceFontSubstitution property.
Although the PrintTicket and PrintCapabilities classes cannot be inherited, you can extend the Print Schema to recognize print device features that are not accounted for in the PrintTicket or PrintCapabilities classes. For more information, see How to: Extend the Print Schema and Create New Print System Classes.
The following example shows how to determine printer capabilities and configure the print job to take advantage of them.
