The printer-based cache is the cache the document uses when it executes printer-based. The size of this cache depends on the document.
You use the Max form cache option in the Document dialog box to set the size of the printer cache. You can also use the Max form item option to set the maximum size of any item in the cache.
When the document executes printer-based, it uses the printer-based cache for both image resources and external images any dynamic images reference.
