Introduction
Compile-Ahead Technology
Pioneered by QMS, compile-ahead technology is the temporary stor-
age of page images in a proprietary compressed data format. It
makes maximum use of the memory resource. While the engine is
busy printing a page, compile-ahead technology uses the available
printer memory to prepare the subsequent pages of the document (or
the next job). These page images are available as soon as the current
page is printed. For example, while the QMS 4060 Print System is
actually printing the third page of a five-page document, pages four,
five, and the next job in the queue are already compiled into the com-
pressed data format.
User Benefit—With compile-ahead technology you spend less time
waiting for documents to print. This increases your productivity.
Compressed Data Formats
Crown printers convert data received by the input buffers into interme-
diate, compressed blocks until the data is needed for printing. These
compressed blocks of data are designed to be processed rapidly by
the printer, and many more can be stored in memory at one time than
can traditional bitmapped images.
User Benefit—This allows and increases the speed of such printer
features as collation and automatic jam recovery.
Automatic Jam Recovery
Crown technology also provides automatic jam recovery. With many
non-QMS printers, if a media jam occurs, you must remove the
jammed media and then reprint the job. On your printer, if a media
jam occurs, once you clear the jam, the printer reprints the jammed
page and continues with the print job. This is possible because com-
pressed data formats allow more pages to be stored in memory. The
printer remembers the last page printed, pulls the necessary interme-
diate blocks from memory, and automatically reprints any lost pages.
User Benefit—This saves time and conserves print media.
