Abstract
System and methods for printing are provided. One such method includes determining a storage capacity available for use as a rasterizer buffer, and implementing a rasterizer buffer having a storage capacity that is responsive to the storage capacity determined to be available for use as a rasterizer buffer.
Claims29
A method for printing, comprising:
- determining a storage capacity available for use as a rasterizer buffer;
- and
- implementing a rasterizer buffer having a storage capacity that is responsive to the storage capacity determined to be available for use as a rasterizer buffer.
A method for printing, comprising:
- determining a storage capacity available for use as a rasterizer buffer;
- and
- rasterizing a first portion of content to be printed, the size of the first portion being responsive to the storage capacity determined to be available for use as a rasterizer buffer.
A host comprising:
- memory;
- and
- a processor that is coupled to the memory and that is programmed to:
- determine a storage capacity of the memory available for use as a rasterizer buffer;
- and
- implement a rasterizer buffer in the memory, the rasterizer buffer having a storage capacity that is responsive to the storage capacity of the memory determined to be available for use as a rasterizer buffer.

A method for printing, comprising:
- determining a storage capacity available for use as a rasterizer buffer;
- implementing a rasterizer buffer having a storage capacity that is responsive to the storage capacity determined to be available for use as a rasterizer buffer;
- buffering bitmap data in the rasterizer buffer, wherein the bitmap data is configured to be printed on a page;
- providing the bitmap data to a spooler;
- providing the bitmap data to a printer driver;
- and
- providing the bitmap data to a printer;
- wherein the bitmap data encodes a plurality of pixel lines;
- wherein the storage capacity of the rasterizer buffer is less than the storage capacity determined to be available for use as a rasterizer buffer;
- wherein the storage capacity determined to be available for use as a rasterizer buffer is inversely correlated to an amount of random access memory (RAM) that is currently being used;
- wherein the bitmap data is generated based on at least one drawing operation that encodes content that is to be located at least in part within a portion of a printed page corresponding to the bitmap data;
- wherein the rasterizer buffer is implemented in random access memory (RAM)
