JobHoldUntil is a printing attribute class, a date-time
attribute, that specifies the exact date and time at which the job must
become a candidate for printing.
If the value of this attribute specifies a date-time that is in the future,
the printer should add the JobStateReason value of
JOB_HOLD_UNTIL_SPECIFIED to the job's
JobStateReasons attribute, must move the job to the
PENDING_HELD state, and must not schedule the job for printing until
the specified date-time arrives.
When the specified date-time arrives, the printer must remove the
JobStateReason value of
JOB_HOLD_UNTIL_SPECIFIED from the job's
JobStateReasons attribute, if present. If there are
no other job state reasons that keep the job in the PENDING_HELD
state, the printer must consider the job as a candidate for processing by
moving the job to the PENDING state.
If the specified date-time has already passed, the job must be a candidate
for processing immediately. Thus, one way to make the job immediately become
a candidate for processing is to specify a JobHoldUntil attribute
constructed like this
(denoting a date-time of January 1, 1970, 00:00:00 GMT):
JobHoldUntil immediately = new JobHoldUntil (new Date (0L));
If the client does not supply this attribute in a Print Request and the
printer supports this attribute, the printer must use its
(implementation-dependent) default JobHoldUntil value at job
submission time (unlike most job template attributes that are used if
necessary at job processing time).
To construct a JobHoldUntil attribute from separate values of the
year, month, day, hour, minute, and so on, use a Calendar
object to construct a Date object, then use the
Date object to construct the JobHoldUntil attribute. To
convert a JobHoldUntil attribute to separate values of the year,
month, day, hour, minute, and so on, create a Calendar
object and set it to the Date from the JobHoldUntil
attribute.
IPP Compatibility: Although IPP supports a "job-hold-until" attribute
specified as a keyword, IPP does not at this time support a "job-hold-until"
attribute specified as a date and time. However, the date and time can be
converted to one of the standard IPP keywords with some loss of precision;
for example, a JobHoldUntil value with today's date and 9:00pm local
time might be converted to the standard IPP keyword "night". The category
name returned by getName() gives the IPP attribute name.
