Secure printing for M5035

[buzz]

Currently the hplip package is not shipping secure printing support for the HP M5035 although it is working fine if the hpps filter is invoked. The only thing you need to do is to add the line:

*cupsFilter: "application/vnd.cups-postscript 0 hpps"

to the ppd-file. Can you please add the support in the next release?

Thanks

TCP dump of a document printed with pin enabled

Description of problem:
Printing a document with secure printing enabled prints the document immediately without asking for a PIN

Version-Release number of selected component (if applicable):
3.13.6 and 3.13.7

How reproducible:
Always

Steps to Reproduce:
1. Select document to print
2. Enable secure printing in the options and set pin code
3. Hit print button

Actual results:
Printer immediately starts the job without prior asking for the user/PIN code

Expected results:
Printer asks for user and PIN code before printing the document.

Additional info:
I've added the tcp stream of a job printed with and one without secure printing enabled. Obviously the PJL header containing the secure printing hints is missing in both printed documents.

Looks like this only works if the PPD options are sent as job options for the job.

I did a small comparison with Ubuntu, where pin printing works. The big important difference is that in ubuntu hpps filter is invoked and not in fedora. According to the hpps source it is responsible for pin printing and the missing pjl header. So how can we add hpps to the filter list?

[Jan-Michael (jan-michael-redhat-bugs)]

The reason for secure printing not working with the M5035 model is the missing filter line

*cupsFilter: "application/vnd.cups-postscript 0 hpps"

in the printer PPD file. As soon as it is added secure printing works fine! So, can you please add it to the official PPD file?

How would we check if there are other models which suffer the same issue?

First one can check the other installed PPD files for the pin printing dat and then double check that the filter is set.
Better would that HP who should know their printers will fix this issue. Who is responsible for this bug and when will it get fixed? So far we have zero response.

This message is a notice that Fedora 19 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 19. It is
Fedora's policy to close all bug reports from releases that are no

be closed as EOL if it remains open with a Fedora 'version' of '19'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not

to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

[Fedora (fedora-redhat-bugs)]

Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
