The Draft IPP Job and Printer Extensions - Set 2 (JPS2) specification is up
for PWG Last Call with comments due this Friday, August 27.  See Ira's
reminder at the end of this email for how to do this.  

The intent of this email is to encourage member companies to submit their
comments, if any.  This email has the current abstract and the list of the
technical changes since the August 3, 2009 version whose technical content
was the same as the version submitted by Xerox seven years ago on 21 August
2002.

Here is the current Abstract:

Abstract: This Job and Printer Extensions - Set 2 Specification (JPS2)
defines an extension to the Internet Printing Protocol/1.0 (IPP) ([RFC2565],
[RFC2566]), IPP/1.1 ([RFC2910], [RFC2911]), and [RFC3380].  This JPS2
consists of a REQUIRED Job Template attribute to print a proof print(s) of
the job prior to printing the full run of the job and OPTIONAL Job Template
attributes for submitting print jobs that permit a user to save jobs for
later reprinting (i.e., retain the jobs indefinitely), provide a recipient
name and a job phone number, provide the feed orientation, provide the font
name and font size, hold a job until a specific date and time, delay the
output of a job (but allow processing) until a specified time period, delay
the output of a job (but allow processing) until a specific date and time,
and specify an interpreter initialization file.
  
This JPS2 also defines four new REQUIRED operations - Cancel-Jobs,
Cancel-My-Jobs, Close-Job, and Resubmit-Job - and a new REQUIRED "job-ids"
operation attribute to be used with the existing Get-Jobs and Purge-Jobs
operations. Cancel-Jobs allows an operator/administrator to cancel a list of
Not Completed jobs or all Not Completed jobs on the Printer. Cancel-My-Jobs
allows a user to cancel a list of their Not Completed jobs or all their Not
Completed jobs. Close-Job allows a client to close a multi-document job
without supplying any additional documents (to support streaming clients and
servers).  Resubmit-Job allows a user to re-process a modified copy of a
Retained Job. Get-Jobs with the "job-ids" attribute allows a user to get a
list of jobs. Purge-Jobs with the "job-ids" attribute allows an
operator/administrator to purge a list of jobs. There are also Printer
Description attributes to list the Job Creation attributes supported,
indicate whether jobs are spooled, and list the set of media collections
supported.  In addition, conformance to JPS2 also REQUIRES support of the
Reprocess-Job operation defined in [RFC3998].

Some of the Job Template attributes defined in this specification are also
defined to be supplied as Operation attributes in the Hold-Job ([RFC2911])
and Set-Job-Attributes ([RFC3380]) operations.

In addition, OPTIONAL semantics for Attribute Precedence, a Queue Override
Feature, and a feature to guarantee protocol precedence over the PDL
attribute are defined.



Here is the summary of the technical changes to the Draft IPP Job and
Printer Extensions - Set 2 (JPS2) since August 3, 2009 (in order to keep
this list short, the non-technical changes, such as new diagrams,
reformatting tables, editorial improvement, adding terminology, etc. is not
included):

1.	Added the following REQUIRED operations (the original 2002 draft had
no new operations defined):
a.	Cancel-Jobs - allows an operator/administrator to cancel a list of
Not Completed jobs or all Not Completed jobs on the Printer.
b.	Cancel-My-Jobs - allows a user to cancel a list of their Not
Completed jobs or all their Not Completed jobs.
c.	Close-Job - allows a client to close a multi-document job without
supplying any additional documents (to support streaming clients and
servers).
d.	Resubmit-Job - prints a Retained Job using the same job template
attributes as the saved job, creating a new job (and job ID).
2.	Made a Saved Job a special case of a Retained Job (when the client
supplies the "job-save-disposition" (collection) Job Template attribute).
Use the job's “job-id” integer(1:MAX) as the handle to uniquely identify
jobs saved using the Reprocess-Job (defined in RFC 3998) and Resubmit-Job
(new) in a Printer context, instead of “document-uri” (uri).  Therefore,
multiple Saved Jobs can have the same "job-name", since they are uniquely
distinguished by their "job-id".  Do NOT use the existing Print-URI
operation to reprint Saved Jobs.  Removed the discussion about Virtual File
Name to identify Saved Jobs, since the "job-id" is now used.
3.	Made a Proof Print Job a special case of a Retained Job (when the
client supplies the "proof-print" (collection) Job Template attribute), so
the Proof Print Job winds up in the 'completed' state, rather than the
'pending-held' state while being proof read by a human.   The Printer MUST
retain the job for an implementation-defined time period that is
sufficiently long for the user to be able to proof read the output of the
Proof Print job and SHOULD be longer than the aging of normal completed
jobs.  When the user reprints the Proof Print Job (using either the
Resubmit-Job or Reprocess-Job operation), the “proof-print” (collection)
attribute is not copied to the new job.
4.	Added the "job-delay-output-until" (type3 keyword | name(MAX) and
"job-delay-output-until-time" (dateTime) Job Template attributes which delay
any output until the specified time period or time, respectively, but allow
the Printer to start processing the job.
5.	Added a REQUIRED "job-ids" Operation attribute to the existing
Get-Jobs and Purge-Jobs operations defined in [RFC2911].
6.	Added 'saved' and 'proof-print' keywords to the "which-jobs"
operation attribute used in (1) the Get-Jobs operation and (2)
"which-jobs-supported" Printer Description attribute.
7.	Added the following "job-state-reasons" values:
a.	'job-delay-output-until-specified'
b.	'job-printed-successfully'
c.	'job-printed-with-errors'
d.	'job-printed-with-warnings'
8.	Removed the following "job-state-reasons" values:
a.	'job-proof-wait'
b.	'job-scheduling'
9.	Changed the data type of the "job-phone-number" Job Template
attribute from text(127) to tel: URI (REQUIRED, if supporting
"job-phone-number") with fax: scheme as OPTIONAL.
10.	Extended the length of the data type of "job-password-supported"
Printer Description attribute from integer(0:127) to integer(0:255), since
the password that the client can supply with the "job-password" Operation
attribute can be 255 octets. 
11.	To the "media-type" member attribute of the "media-col" Job Template
attribute: Added a large number of keywords from [JDF1.4] MediaType and
MediaTypeDetails, including the five keywords from “media-material”
('aluminum', 'dry-film', 'paper', 'polyester', 'wet-film') and removed the
“media-material” attribute altogether.
12.	Added the following Printer Description attributes:
a.	"job-ids-supported" (boolean)
b.	"save-name-subdirectory-supported' (boolean)
c.	"pdl-init-file-name-subdirectory-supported" (boolean)
