This object sets the PageSize to be used by this interpreter in reserving sufficient memory for printing complex pages, thus avoiding Page Too Complex Errors. The actual amount of memory to be reserved as a function of the specified page size is implementation specific. When this feature is turned on, printer performance may be slowed.

In PCL, this object supports the General PJL Environment Variable 'PAGEPROTECT'. This object the sets the page protection configuration. The page protection feature reserves a block of printer memory to prevent printer overrun errors when formatting very dense or complex images. This variable may be set to any legal value at any time, regardless of the current amount of free memory or the currently set resolution. When a job is sent, if there is not enough memory to print correctly with the current resolution and page protection configuration, the system temporarily overrides the resolution and/or page protect values to run the job. When the page protection status is changed, memory may be reconfigured, and all downloaded fonts, PCL macros, and PostScript dictionaries may be lost.

The value notSpecified shall also mean Off.
