[cups-devel] Using cups API to send PDF document without converting to PS first

[Nimesh Amin]

Got it, thanks for explaining that. Nothing to be concerned about the

job-password isn't supported, which is why I need to set the "@PJL SET
SOMEKEY = VALUE" entry via cupsAddOptions.  Looking at the tcpdump, the
option isn't being set.
