PrintCapabilities Class

Defines the capabilities of a printer.


Namespace:  System.Printing
Assembly:  ReachFramework (in ReachFramework.dll)

public sealed class PrintCapabilities

The PrintCapabilities type exposes the following members.

Public methodPrintCapabilitiesInitializes a new instance of the PrintCapabilities class by using an XML stream (that contains a PrintCapabilities document) that specifies printer capabilities and complies with the XML Print Schema.

Public propertyCollationCapabilityGets a collection of values that identify the collation capabilities of a printer.
Public propertyDeviceFontSubstitutionCapabilityGets a collection of values that identify whether and how a printer can substitute device-based fonts for computer-based fonts.
Public propertyDuplexingCapabilityGets a collection of values that identify whether and how a printer can perform two-sided printing.
Public propertyInputBinCapabilityGets a collection of values that indicate what input bin (paper tray) is used.
Public propertyMaxCopyCountGets a value indicating the maximum number of copies that the device can print in a single print job.
Public propertyOrientedPageMediaHeightGets a value indicating the height of the imageable area on a page, where height means the vertical dimension relative to the page's orientation.
Public propertyOrientedPageMediaWidthGets a value indicating the width of the imageable area on a page, where width means the horizontal dimension relative to the page's orientation.
Public propertyOutputColorCapabilityGets a collection of values that specify the ways in which a printer can print content with color and shades of gray.
Public propertyOutputQualityCapabilityGets a collection of values that indicate the types of output quality the printer supports.
Public propertyPageBorderlessCapabilityGets a collection of values that indicate whether the printer can print up to the edge of the media.
Public propertyPageImageableAreaGets an object that represents the area of a page that the printer can use.
Public propertyPageMediaSizeCapabilityGets a collection of PageMediaSize objects that identify the paper and media sizes that a printer supports.
Public propertyPageMediaTypeCapabilityGets a collection of values that identify what types of paper and other media a printer supports.
Public propertyPageOrderCapabilityGets a collection of values that indicate whether a printer is capable of printing multiple-page documents from front-to-back, back-to-front, or both ways.
Public propertyPageOrientationCapabilityGets a collection of values that identify what types of page orientation a printer supports.
Public propertyPageResolutionCapabilityGets a collection of PageResolution objects that identify what levels of page resolution the printer supports.
Public propertyPageScalingFactorRangeGets the maximum and minimum percentages by which a printer can enlarge or reduce the print image on a page.
Public propertyPagesPerSheetCapabilityGets a collection of integers, each identifying the number of pages that a user can choose to print on a single side of a sheet of paper.
Public propertyPagesPerSheetDirectionCapabilityGets a collection of values that identify what patterns a printer supports for presenting multiple pages on a single side of a sheet of paper.
Public propertyPhotoPrintingIntentCapabilityGets a collection of values that identify the quality options the printer supports for printing photographs.
Public propertyStaplingCapabilityGets a collection of values that identify the types of automatic stapling that a printer supports.
Public propertyTrueTypeFontModeCapabilityGets a collection of values that identify the methods that a printer supports for handling TrueType fonts.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

A PrintCapabilities object is an easy-to-work-with representation of a certain type of XML document called a PrintCapabilities document. The latter is a snapshot of all of a printer's capabilities and their current settings. For example, if the printer supports color printing, then the document would have a <PageOutputColor … > element that sets out how color output will be handled. The element is, in turn, represented by the OutputColorCapability property of the PrintCapabilities object. If the printer does not support color, then there is no <PageOutputColor … > element in the document and the value of the OutputColorCapability property is null. The PrintCapabilities document must conform to the Print Schema.

The PrintCapabilities class enables your application to obtain a printer's capabilities without having to engage in any direct reading of XML Stream objects.

All of the most popular features of file and photo printers, for both home and business, are encapsulated by the PrintCapabilities class. But the Print Schema defines many more, less common, features and it can be extended to handle features of specialty printing devices. So, 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.

Note   When the PrintCapabilities object is created with the constructor that takes a PrintCapabilities document (as a Stream) parameter, that entire document is stored in a non-public field in the object, including the XML elements within it that express less common features that are not represented by any of the public properties of the PrintCapabilities class. In fact, if the driver that produced the PrintCapabilities document is using a private extension of the Print Schema, that privately defined markup is also stored as part of the non-public PrintCapabilities document.

The following example shows how to determine the capabilities of a specific printer and how to configure a print job to take advantage of them.

// ---------------------- GetPrintTicketFromPrinter -----------------------
/// <summary>
///   Returns a PrintTicket based on the current default printer.</summary>
/// <returns>
///   A PrintTicket for the current local default printer.</returns>
private PrintTicket GetPrintTicketFromPrinter()
    PrintQueue printQueue = null;

    LocalPrintServer localPrintServer = new LocalPrintServer();

    // Retrieving collection of local printer on user machine
    PrintQueueCollection localPrinterCollection =

    System.Collections.IEnumerator localPrinterEnumerator =

    if (localPrinterEnumerator.MoveNext())
        // Get PrintQueue from first available printer
        printQueue = (PrintQueue)localPrinterEnumerator.Current;
        // No printer exist, return null PrintTicket
        return null;

    // Get default PrintTicket from printer
    PrintTicket printTicket = printQueue.DefaultPrintTicket;

    PrintCapabilities printCapabilites = printQueue.GetPrintCapabilities();

    // Modify PrintTicket
    if (printCapabilites.CollationCapability.Contains(Collation.Collated))
        printTicket.Collation = Collation.Collated;

    if ( printCapabilites.DuplexingCapability.Contains(
            Duplexing.TwoSidedLongEdge) )
        printTicket.Duplexing = Duplexing.TwoSidedLongEdge;

    if (printCapabilites.StaplingCapability.Contains(Stapling.StapleDualLeft))
        printTicket.Stapling = Stapling.StapleDualLeft;

    return printTicket;
}// end:GetPrintTicketFromPrinter()
