| PrinterResolution | | final public class PrinterResolution extends ResolutionSyntax implements DocAttribute,PrintRequestAttribute,PrintJobAttribute(Code) | | Class PrinterResolution is a printing attribute class that specifies an
exact resolution supported by a printer or to be used for a print job.
This attribute assumes that printers have a small set of device resolutions
at which they can operate rather than a continuum.
PrinterResolution is used in multiple ways:
-
When a client searches looking for a printer that supports the client's
desired resolution exactly (no more, no less), the client specifies
an instance of class PrinterResolution indicating the exact resolution the
client wants. Only printers supporting that exact resolution will match the
search.
-
When a client needs to print a job using the client's desired resolution
exactly (no more, no less), the client specifies an instance of class
PrinterResolution as an attribute of the Print Job. This will fail if the
Print Job doesn't support that exact resolution, and Fidelity is set to
true.
If a client wants to locate a printer supporting a resolution
greater than some required minimum, then it may be necessary to exclude
this attribute from a lookup request and to directly query the set of
supported resolutions, and specify the one that most closely meets
the client's requirements.
In some cases this may be more simply achieved by specifying a
PrintQuality attribute which often controls resolution.
IPP Compatibility: The information needed to construct an IPP
"printer-resolution" attribute can be obtained by calling
methods on the PrinterResolution object. The category name returned by
getName() gives the IPP attribute name.

| Constructor Summary | |
| public | PrinterResolution(int crossFeedResolution, int feedResolution, int units)
Construct a new printer resolution attribute from the given items. |
| Method Summary | |
| public boolean | equals(Object object)
Returns whether this printer resolution attribute is equivalent to the
passed in object. | | final public Class<? extends Attribute> | getCategory()
Get the printing attribute class which is to be used as the "category"
for this printing attribute value.
For class PrinterResolution, the category is class PrinterResolution itself. | | final public String | getName()
Get the name of the category of which this attribute value is an
instance. |
| PrinterResolution | | public PrinterResolution(int crossFeedResolution, int feedResolution, int units)(Code) | | Construct a new printer resolution attribute from the given items.
Parameters:
crossFeedResolution - Cross feed direction resolution.
Parameters:
feedResolution - Feed direction resolution.
Parameters:
units - Unit conversion factor, e.g. ResolutionSyntax.DPIor ResolutionSyntax.>DPCM.
exception:
IllegalArgumentException - (unchecked exception) Thrown if crossFeedResolution < 1 or feedResolution < 1 or units < 1. |
| equals | | public boolean equals(Object object)(Code) | | Returns whether this printer resolution attribute is equivalent to the
passed in object. To be equivalent, all of the following conditions
must be true:
-
object is not null.
-
object is an instance of class PrinterResolution.
-
This attribute's cross feed direction resolution is equal to
object's cross feed direction resolution.
-
This attribute's feed direction resolution is equal to
object's feed direction resolution.
Parameters:
object - Object to compare to. True if object is equivalent to this printerresolution attribute, false otherwise. |
| getCategory | | final public Class<? extends Attribute> getCategory()(Code) | | Get the printing attribute class which is to be used as the "category"
for this printing attribute value.
For class PrinterResolution, the category is class PrinterResolution itself.
Printing attribute class (category), an instance of classjava.lang.Class java.lang.Class. |
| getName | | final public String getName()(Code) | | Get the name of the category of which this attribute value is an
instance.
For class PrinterResolution, the
category name is "printer-resolution".
Attribute category name. |
