Class PrinterState

java.lang.Object

  +--javax.print.attribute.EnumSyntax

        +--javax.print.attribute.standard.PrinterState

All Implemented Interfaces:: Attribute, Cloneable, PrintServiceAttribute, Serializable

public final class PrinterState
extends EnumSyntax
implements PrintServiceAttribute

Class PrinterState is a printing attribute class, an enumeration, that identifies the current state of a printer. Class PrinterState defines standard printer state values. A Print Service implementation only needs to report those printer states which are appropriate for the particular implementation; it does not have to report every defined printer state. The PrinterStateReasons attribute augments the PrinterState attribute to give more detailed information about the printer in given printer state.

IPP Compatibility: The category name returned by getName() is the IPP attribute name. The enumeration's integer value is the IPP enum value. The toString() method returns the IPP string representation of the attribute value.
