There already exist CPL based header file for JTAPI job elements and an approved

This approach could reduce the 1800 bytes / page overhead of CUPS Raster 2 to a
few bytes if no page override needed (the most likely use case) along with
alignment of other small details in CUPS raster.<o:p></o:p></span></font></p>

that it cannot be based on an existing vendor, industry, or group standard. In
fact, most PWG standards are necessarily based on existing standards from
different sources. That said, if you have an alternative existing format you
