Pioneered by QMS, compile-ahead technology makes use of tempo-
rary storage 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 2425/2425
TURBO
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 compressed data format.
User Benefit—With compile-ahead technology you spend less time
waiting for documents to print. This increases your productivity.

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 increases the speed of the printer and allows for
advanced document features such as collation and automatic jam
recovery.

Crown technology also provides automatic jam recovery. With most
printers, if a media jam occurs, you must remove the jammed media
and then re-send 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 compressed data formats
allow more pages to be stored in memory. The printer remembers the
last page printed, pulls the necessary intermediate blocks from mem-
ory, and automatically reprints any lost pages.
User Benefit—This saves time and conserves print media.
