All,

I have posted an updated stable (LCRC) draft of the IPP 3D Printing Extensions to:

	http://ftp.pwg.org/pub/pwg/ipp/wd/wd-ipp3d10-20170110.docx
	http://ftp.pwg.org/pub/pwg/ipp/wd/wd-ipp3d10-20170110.pdf
	http://ftp.pwg.org/pub/pwg/ipp/wd/wd-ipp3d10-20170110-rev.pdf

The only change in this version was to add the (missing) "max-materials-col-supported" Printer Description attribute to Table 5 (required Printer Description attributes).

Greetings,

Here's what I have so far in updating section 5.3, but I would =
appreciate any editorial help on this:

5.3=C2=A0job-pages-per-set (integer(1:MAX)) <>
The RECOMMENDED "job-pages-per-set" Job Template attribute specifies the =
number of input pages that constitute a set for finishing processes, for =
scenarios where the Printer does not support the "copies" attribute =
[RFC2911] for a given document format, and the Client generates the =
copies in the Document content. If the Printer supports the "copies" Job =
Template attribute for a given document format, the Printer SHOULD NOT =
support the "job-pages-per-set" attribute for that same document format. =
If both are supported for a given document format, when =
"job-pages-per-set" is specified, "copies" MUST be 1 or omitted since =
the purpose of the attribute is to specify that the document data =
contains copies generated by the Client. Specifying "job-pages-per-set" =
implicitly overrides any "copies" / "copies-default" value to 1. The =
value of "job-pages-per-set" MUST be evenly divisible with the number of =
Input Pages since it is being used to demarcate the length of a single =
copy. See the sections on the "multiple-document-handling" Job Template =
attribute [RFC2911] for more information on using this attribute with =
multiple Document Jobs.

To illustrate how the "job-pages-per-set" attribute ought to be =
employed, if a Client submits a 14 page PWG Raster Format [PWG5102.4] =
Document for printing that contains two copies of four duplex pages =
each, the Client might specify a "job-pages-per-set" Job Template =
attribute with a value of 7, a "sides" attribute with a value of =
'two-sided-long-edge', and a "finishings" attribute with a value of 4 =
(staple) to have the Printer staple two Sets of four sheets. Figure 4 =
shows a graphical representation of this example.

Greetings,

I remember back when I was doing the IPP Implementor's Guide v2 we had =
discussed a "Get-User-Supported-Values" operation, that would provide =
the list of supported attributes for a given user. Now that we are a few =
years on from that, and in the middle of System Service, what is the =
current IPP WG thinking about where such an operation ought to be =
defined?

Smith,

The thinking before was that the proposer would put together a white paper so that we could formally discuss things and propose it as new work for the IPP WG.  Given the scope, this won't be a huge undertaking (probably on the order of 10 pages, including boilerplate), but it is a necessary step so that everyone is on the same page.

FWIW, I do not think this should be added to IPP System Service since this operation is targeted at the job services (Print, FaxOut, Scan) and *not* for the System service.

Smith,

How about:

5.3 job-pages-per-set (integer(1:MAX))

The RECOMMENDED "job-pages-per-set" Job Template attribute specifies the =
number of input pages that constitute a set for finishing processes. It =
is used when the Client generates the copies in the Document content =
because the Printer does not support the "copies" attribute [RFC2911] =
for the given Document format. If the Client includes the =
"job-pages-per-set" Job Template attribute in a Job Creation request:

- The Client SHOULD NOT include the "copies" Job Template attribute, or =
if included MUST use the value 1; and
- The Printer MUST ignore the value of the "copies-default" Printer =
Description attribute.

The value of "job-pages-per-set" MUST be evenly divisible with the =
number of Input Pages since it is being used to demarcate the length of =
a single copy or Set. See the sections on the =
"multiple-document-handling" Job Template attribute [RFC2911] for more =
information on using this attribute with multiple Document Jobs.

For example, if a Client submits a 14 page PWG Raster Format [PWG5102.4] =
Document for printing that contains two copies of four duplex pages =
each, the Client might specify a "job-pages-per-set" Job Template =
attribute with a value of 7, a "sides" attribute with a value of =
'two-sided-long-edge', and a "finishings" attribute with a value of 4 =
(staple) to have the Printer staple two Sets of four sheets. Figure 4 =
shows a graphical representation of this example.

Hi Smith,

I agree with Mike that this operation should not be added to IPP System
Service.

I question the need for this operation.

An IPP job service implementation can filter a Get-Printer-Attributes
response already based on authenticated user identity.

What new functionality would this putative operation add to IPP?

Cheers,
- Ira

Right now clients need to use Validate-Job (which *is* authenticated for printers that do authentication of print jobs) in order to validate the choices a user has made.

It would be defined as an authenticated version of Get-Printer-Attributes that explicitly filters the values based on the authenticated identity of the requestor.

Hi Mike,

Thanks for those clarifications.

I suggest the proposed new operation be named "Get-User-Printer-Attributes"
to show the authenticated User dependence and the otherwise similarity to
the classic "Get-Printer-Attributes" operation.

I agree that a brief whitepaper is appropriate.

I have strong reservations about adding a new operation (as opposed to some
attributes) simply via IPP WG approval for IANA registration.  We should
talk
more about where this operation might be published.

Cheers,
- Ira

Ira,

The registration policy for operations is Expert Review, so a full specification is not technically required. That said, we (the designated experts) and the IPP workgroup can require sufficient clarity in the definition of the operation before such a registration is approved, or to require a spec of the scope of the registration is (in the opinion of the WG or designated experts) too broad for a simple registration.

In the case of this operation, we simply (IMHO) do not have enough information to decide.

(integer(1:MAX))<br class=3D""><br class=3D"">The RECOMMENDED =
"job-pages-per-set"&nbsp;Job Template attribute specifies the number of =
input pages that constitute a&nbsp;set for finishing&nbsp;processes, for =
scenarios where the Printer does not support the&nbsp;"copies" =
attribute&nbsp;[RFC2911]&nbsp;for a given document format, and the =
Client&nbsp;generates&nbsp;the copies in the Document content. If the =
Printer supports the "copies"&nbsp;Job Template attribute for a given =
document format, the&nbsp;Printer SHOULD NOT&nbsp;support the =
"job-pages-per-set" attribute for that same document&nbsp;format. If =
both are supported for a given&nbsp;document format, =
when&nbsp;"job-pages-per-set" is specified, "copies" MUST be 1 =
or&nbsp;omitted since the purpose of the attribute is to =
specify&nbsp;that the document data&nbsp;contains copies generated by =
the Client. Specifying&nbsp;"job-pages-per-set" implicitly overrides any =
"copies" / "copies-default"&nbsp;value to 1. The value of =
"job-pages-per-set" MUST be evenly divisible&nbsp;with the number of =
Input Pages since it is being used to&nbsp;demarcate the length&nbsp;of =
a single copy. See the sections on the =
"multiple-document-handling"&nbsp;<wbr class=3D"">Job Template attribute =
[RFC2911] for more&nbsp;information on using this attribute&nbsp;with =
multiple Document Jobs.<br class=3D""><br class=3D"">To illustrate how =
the "job-pages-per-set" attribute ought to be employed, if a Client =
submits a 14 page PWG Raster Format [PWG5102.4]&nbsp;Document for =
printing that contains two copies of four duplex pages each, the Client =
might specify a "job-pages-per-set" Job Template&nbsp;attribute with a =
value of 7, a "sides" attribute with a value of 'two-sided-long-edge', =
and a "finishings" attribute with a value of 4 (staple) to&nbsp;have the =
Printer staple two Sets of four sheets. Figure 4 shows a graphical =
representation of this example.<br class=3D""><br class=3D""><br =

Hi Mike and Smith,

I suggest that the parameters and attributes of such an operation

are exactly the same as Get-Printer-Attributes, except that the User
identity MUST be authenticated and MUST be authorized (via some
out-of-band manner) to perform the new operation.

It might be appropriate to abandon the "limit" and friends and also
to say that you can't read "media-col-database" with this operation.
It might also be appropriate to abandon "requested-attributes" and
just return all the simple attributes and "xxx-supported" attributes.

Smith - please think about the use case(s) and propose by email
some more details for discussion as a next step.

Cheers,
- Ira

Ira,

The point of the operation is for a Client UI to be able to show the attributes and values the user is allowed to select, which necessarily includes things like "media-col-database".  The user may be identified through requesting-user-name, authenticated user name, source IP, client certificate, etc., with the details of any filtering being an implementation detail.

Defining "Get-User-Supported-Values" as analogous to "Get-Printer-Attributes" except that the operation filters the attributes and values based on the (most authenticated) user identity keeps things relatively simple and avoids future "oh shit" moments when we realize we added too many restrictions.  And for conformance we'll want to require Client and Printer support for authentication but not require a Printer to use authentication, i.e., an allowed configuration is to just rely on the requesting-user-name, source IP, etc.

Ideally, a Printer should not advertise the new operation unless it will be performing some sort of filtering - that allows for simple client-side optimizations when printer capabilities are not limited by user or other Client metadata.

Hi Mike,

You are suggesting this new Get-User-Printer-Attributes operation
does NOT require authentication and authorization of the Client?

If that's right, what value does this operation offer over the classic
Get-Printer-Attributes (with perhaps an "ipp-features-supported"
tag that says it supports User-based filtering)?

My reading of original RFC 2911 was that *any* operation could do
filtering based on the requesting user (i.e., Get-Jobs).

Confused,
- Ira

The point of the operation is for a Client UI to be able to show the attrib=
utes and values the user is allowed to select, which necessarily includes t=
hings like &quot;media-col-database&quot;.=C2=A0 The user may be identified=
 through requesting-user-name, authenticated user name, source IP, client c=
ertificate, etc., with the details of any filtering being an implementation=
 detail.<br>
<br>
Defining &quot;Get-User-Supported-Values&quot; as analogous to &quot;Get-Pr=
inter-Attributes&quot; except that the operation filters the attributes and=
 values based on the (most authenticated) user identity keeps things relati=
vely simple and avoids future &quot;oh shit&quot; moments when we realize w=
e added too many restrictions.=C2=A0 And for conformance we&#39;ll want to =
require Client and Printer support for authentication but not require a Pri=
nter to use authentication, i.e., an allowed configuration is to just rely =
on the requesting-user-name, source IP, etc.<br>
<br>
Ideally, a Printer should not advertise the new operation unless it will be=
 performing some sort of filtering - that allows for simple client-side opt=
imizations when printer capabilities are not limited by user or other Clien=
t metadata.<br>

&gt; Hi Mike and Smith,<br>
&gt;<br>
&gt; I suggest that the parameters and attributes of such an operation<br>
&gt;<br>
&gt; are exactly the same as Get-Printer-Attributes, except that the User<b=
r>
&gt; identity MUST be authenticated and MUST be authorized (via some<br>
&gt; out-of-band manner) to perform the new operation.<br>
&gt;<br>
&gt; It might be appropriate to abandon the &quot;limit&quot; and friends a=
nd also<br>
&gt; to say that you can&#39;t read &quot;media-col-database&quot; with thi=
s operation.<br>
&gt; It might also be appropriate to abandon &quot;requested-attributes&quo=
t; and<br>
&gt; just return all the simple attributes and &quot;xxx-supported&quot; at=
tributes.<br>
&gt;<br>
&gt; Smith - please think about the use case(s) and propose by email<br>
&gt; some more details for discussion as a next step.<br>

&gt; The registration policy for operations is Expert Review, so a full spe=

&gt;&gt;&gt; I question the need for this operation.<br>
&gt;&gt;&gt;<br>
&gt;&gt;&gt; An IPP job service implementation can filter a Get-Printer-Att=

&gt;&gt;<br>
&gt;&gt; Right now clients need to use Validate-Job (which *is* authenticat=

the choices a user has made.<br>
&gt;&gt;<br>
&gt;&gt;&gt; What new functionality would this putative operation add to IP=

&gt;&gt; It would be defined as an authenticated version of Get-Printer-Att=

No, I am suggesting that this new operation *may* not require Client authentication, depending on the configuration of the Printer, just as Cancel-Job, Cancel-All-Jobs, Cancel-My-Jobs, Create-Job, Get-Job-Attributes, Get-Jobs, Print-Job, Print-URI, Send-Document, Send-URI, and Validate-Job do.

FWIW, Get-Printer-Attributes is basically the only operation in IPP/1.1 (RFC 2911/8011) that does not say anything about authentication, the most authenticated identity, authorization rights, or filtering of attributes or values based on the most authenticated identity.  And that makes it impossible to add authentication requirements without breaking a lot of (read: all) Clients.

It makes it consistent with the Job operations.

No, there is discussion of authentication and the most authenticated user/identity, but specific requirements and filtering are discussed in the description of each operation.  In particular, Get-Jobs and Get-Job-Attributes talk about filtering based on security policy, while Get-Printer-Attributes only talks about filtering based on document format (and basically says everyone gets to see the same information).

This is arguably a bug in the original IPP specs, but there is nothing we can do to fix Get-Printer-Attributes now.
(but there are advantages to having a public/guest "get" operation for discovering what a Printer will require, e.g., "uri-authentication-supported" values...)

Greetings,

I have just posted an updated LCRC stable draft of IPP Finishings 2.1 =
that should resolve all outstanding issues from the LCRC review on =
1/11/17. It is available here:

   http://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippfinishings21-20170117.pdf
   http://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippfinishings21-20170117.docx
   http://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippfinishings21-20170117-rev.pdf
   =
http://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippfinishings21-20170117-rev.docx

The updated list of comments and resolutions is here:

   http://ftp.pwg.org/pub/pwg/ipp/wd/lcrc-ippfinishings21.txt

I believe the expectation is that, if this revision is satisfactory to =
the IPP Workgroup, then this will be considered the final draft and the =
subject of a PWG Formal Vote.

Thanks to all contributors for your assistance!

Cheers,

Smith

Hi,

Smith plans to bring a whitepaper and/or slides on this new operation
(tentatively to be named Get-User-Printer-Attributes for clarity) to the
PWG F2F meeting in February.

On reflection, I suggest that perhaps we *should* add this operation
to IPP System Service to enhance IPP Client interworking with IPP
Printers (job services).

Mike has convinced me that the operation should look just like the
existing Get-Printer-Attributes operation (input/output attributes),
but allow the Printer (if so configured) to authenticate the Client's
requesting user identity and always require filtering of the response
based on the most authenticated requesting user identity.

Cheers,
- Ira

Greetings,

Earlier today, I have posted the initial draft of a technical brief =
whitepaper formally introducing the notion of an IPP =
Get-User-Printer-Attributes operation. It is posted on the PWG FTP site =
here:

http://ftp.pwg.org/pub/pwg/ipp/whitepaper/tb-userop-20170130.pdf =
<http://ftp.pwg.org/pub/pwg/ipp/whitepaper/tb-userop-20170130.pdf>=20
http://ftp.pwg.org/pub/pwg/ipp/whitepaper/tb-userop-20170130.odt =
<http://ftp.pwg.org/pub/pwg/ipp/whitepaper/tb-userop-20170130.odt>=20

The latter document is in Open Document format, which I intend to use as =
the "master" document format. I see in the draft F2F slides that there =
is a slide for this topic, so I am asking that we keep this topic in =
place for the F2F meetings in Sunnyvale in 2 weeks.

Cheers,

Smith
