Printers with automatic or auto-resolution mode

PSF now supports printers operating in automatic or auto-resolution mode, unless they are connected through Distributed Print Function (DPF) or RPM3.

Printers with automatic mode print at a particular pel density (for example, 600-pels per inch), but accept resources at different resolutions, such as 240-pels and 300-pels per inch. The printer then scales the resources appropriately based on their resolution and metric technology.

Printers operating in the auto-resolution mode report to PSF the resolution of the print head (for example, 600-pel). However, they also tell PSF that they accept other resolutions.

In order to exploit this feature, the PSF printer definition must be set up with access to all the different resolution resource libraries for fonts, overlays and page segments. Additionally, PSF must receive an indication of the intended resolution when the print data was formatted. If no intended resolution is given, PSF uses the default JCL DD statement for that resource type.

For more information about how to define these JCL DD statements, see Specifying PRINTDEV parameters.

For an example startup procedure set up for multiple resolution libraries, see Sample PSF startup procedure for four printers.
