Here are some comments from one of the customers that attended our customer
council last week.
I am just passing them on for review/interest. I'll leave it to Scott to
decide if any changes are
required based to the model document based on these comments.

Subject: IPP comments!
here comes a couple of comments of the draft model and semantics.
1, on page 11. regarding a end user find and select printers
based on a directory.
** This directory, how will that work together with a some UNIX
boxes the need to update there "printcap" to be able to us the LPR
Our experience in this area tells us that we do not want a function
that distribute "printcap" files to all UNIX boxes before they are
needed. We did something like that but was forced to use FTP and
then on a local server submit the printjob based on information in
the file name.
2. on page 13. regarding the spooler for a client.
How will this work for a NC box?
3. on page 13. regarding the Gateway.
As i said in Boulder, i have a lot of bad experience with the LPR
function and the possibilities to get a supervised environment
based on that.
4. on page 13. regarding Notification.
a function to be able to turn on and of notify, also have a table
to be able to select what to be notifyed on, like only on errors
but not on paper jam or out of paper.
5. output dev def
To relay on that a printer is able to switch PDL:s is still
Some of the printers out there is not to good to recognise PS like
%%, or %! depending on the printer default is set to PCL or PS.
And also if a file is in the format of HP-GL and are created in a
UNIX box they normally not send the first record as a setup command
The file just begin with pen up, pen down and cordinates.
6. Job priority
I assume that this only reflects on your on jobs, is that right?
7. 4.2.2 Cancel Job Operation.
An administrator like helpdesk functions need to be able to cancel
jobs for a user, this is one of the most common request to a
8. 18.104.22.168.1 As a job attribute
This about a banner page. to be able to control this side from a
client side and to be able to get information from some kind of
administration function. The result will be that the only
information they there is from a sending node will be the IP
address if you rely on LPR.
Also to have a function to address more that one recipient
(printer) of a document and be able to send a readable address list
on the banner page.
A function to address a distribution list
9. 5.2.2 Job notifications
To be able to specify different recipients of an error condition
like paper jam or out of paper to a operator/user and a notify to a
service function if the error code is out of toner or a HW error.
Also a notification possibility to notify a user different than the
user that submit the job.
10 22.214.171.124 Job production attributes
If the printer has all functions like different paper format and so
on, how will get the notification if the user is using a printer on
a different department or company?
I assume the the printer attributes are stored in a directory.
11 126.96.36.199.2 As a Printer attribute
regarding the input-trays.
Should this not include a function to address bin 1 to bin xx for
12 188.8.131.52 Compession
If the printer is connected via a server will the printer attribute
have to match and probably even a version number of the zip
13 184.108.40.206.2 PDL:s
for the language, should it not inclund a version number? Will PS
level 1 be able to print on a PS level 3 printer and so on?
A printer can have many of this PDL:S and here could it be a value
to know if it is a multi PDL printer or if a server is used for
14 220.127.116.11 Job impressions
Is the number physical or logical?
In PS there can be a number of logical impressions on one logical
impression on a physical page (dose that make sense?)
15 18.104.22.168 user locale
The codepage needed for a document is not needed the same as
the the user codepage or what codepage the server has.
16 5.3.3 job status.
As a said in Boulder, this will not give the correct info if LPR is
used and the printer use a spooler/server.
17 5.6 Printer status
as said before if the printer is connected to a server is it the
server status you receive and not the printers.
Another thing is the you are in some cases able to "ping" a node
but regarded to security not allowed to print on it.
Please let me know if you can use anything of above.
