Subject: [PATCH 1/2] Fix delays printing to lpd when reserved ports are
exhausted
cups_rresvport() doesn't reserve ports less than 512; however,
lpd_queue() continues decrementing the port number to 0. This leads
to delays of ~511 seconds once all ports between 512-1023 are
exhausted. Even when ports become available, lpd_queue() still tries
calling cups_rresvport() with port numbers less than 512, waiting one
second between each call.

Subject: [PATCH 1/2] Use "purge-job" instead of "purge-jobs" when canceling a
single job (#742)
The command "cancel -x <job>" adds "purge-jobs true" to the Cancel-Job
operation; however, the correct attribute to use for Cancel-job is
"purge-job" (singular), not "purge-jobs" (plural). As a result, job
files are not removed from /var/spool/cups when "cancel -x <job>" is
executed.
This patch resolves the issue by adding "purge-job" when the IPP
operation is Cancel-Job and "purge-jobs" for other IPP operations
(Purge-Jobs, Cancel-Jobs, and Cancel-My-Jobs)
