  33 /**
  34  * Class PrinterResolution is a printing attribute class that specifies an
  35  * exact resolution supported by a printer or to be used for a print job.
  36  * This attribute assumes that printers have a small set of device resolutions
  37  * at which they can operate rather than a continuum.
  38  * <p>
  39  * PrinterResolution is used in multiple ways:
  40  * <OL TYPE=1>
  41  * <LI>
  42  * When a client searches looking for a printer that supports the client's
  43  * desired resolution exactly (no more, no less), the client specifies
  44  * an instance of class PrinterResolution indicating the exact resolution the
  45  * client wants. Only printers supporting that exact resolution will match the
  46  * search.
  47  *
  48  * <LI>
  49  * When a client needs to print a job using the client's desired resolution
  50  * exactly (no more, no less), the client specifies an instance of class
  51  * PrinterResolution as an attribute of the Print Job. This will fail if the
  52  * Print Job doesn't support that exact resolution, and Fidelity is set to
  53  * true.
  54  * </OL>
  55  * If a client wants to locate a printer supporting a resolution
  56  * greater than some required minimum, then it may be necessary to exclude
  57  * this attribute from a lookup request and to directly query the set of
  58  * supported resolutions, and specify the one that most closely meets
  59  * the client's requirements.
  60  * In some cases this may be more simply achieved by specifying a
  61  * PrintQuality attribute which often controls resolution.
  62  * <P>
  63  * <B>IPP Compatibility:</B> The information needed to construct an IPP
  64  * {@code "printer-resolution"} attribute can be obtained by calling
  65  * methods on the PrinterResolution object. The category name returned by
  66  * {@code getName()} gives the IPP attribute name.
