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, andFidelity
is set to true.
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.
