PostScript (PS) emulation

PostScript paper tray support

When the printer receives one of the operators listed in “Tray selected with tray operators” on page 14, it performs the actions listed in this section. This paper tray selection process ends when a suitable paper source is chosen and paper is fed from this tray.

•The printer checks the value of manualfeed in statusdict and the ManualFeed page device parameter. If either one is true, then the printer sends a message to load the requested size in the manual feeder or multipurpose feeder.

•The PageSize Policy is set to 0 by means of setpagedevice.

•The printer checks the paper size loaded in the current active source to determine if it matches the requested size. If the sizes match, then the paper is fed from the active source.

Note: The current active tray is the last source that was selected from the printer control panel or by the printer language.

•If the requested size and the size loaded in the active source do not match, then the sources are searched in the order defined by the Priority array in the InputAttributes dictionary in the pagedevice dictionary.

•If the requested media size is not found by the previous search, then the following search order is used:

–Tray 1

–Tray 2

–Tray 3

–Multipurpose feeder

–Tray 4

–Tray 5

•If the requested size cannot be located in any automatic source, then a configurationerror is issued and the job is flushed.

For printers that support automatic two‑sided printing (duplexing):

•Automatic two‑sided printing is not supported for custom-size paper or for envelopes in the multipurpose feeder. Automatic two‑sided printing is supported from the multipurpose feeder for all other papers.

•If the paper source is changed before the back side of a two‑sided page prints, then a blank back page prints, the paper source changes, and the information for the back side of the page is printed on the front side of a page sent from the new paper source.

When these operators are used, it is equivalent to executing the following PostScript emulation sequence:

<</PageSize [x y]/ImagingBBox null /Policies << /PageSize 0>> >> setpagedevice

where x y are the PageSize in points.
