IPP request generator to interact with CUPS or IPP devices.

pyipptool's Issues

Implement user function resume_printer

Implement Get-Notifications operation

See Get-Notifications Operation

CUPS-Get-PPDs Operation

1. Use inheritance from GetDevicesOperationAttributes
2. Test: check that the limit parameter is indeed there in the request

Implement functions for the Hold-New-Jobs & Release-Held-New-Jobs operations

Adjust create_printer_subscription to conform to rfc 3995

Small details need to be reviewed. See Create-Printer-Subscriptions Request and more particularly Subscription Template Attributes.

get_job_attributes with job_uri & uri only

Example

Can you please write an example of a script for printing a job, or holding a document then resume the action? Like how do I call the fuction what do I need to import...

Thank you..

Implement Cancel-Subscription

see specs at http://tools.ietf.org/html/rfc3995#section-11.2.7

cups_get_printers - requested_attributes='all' does not work

>>> uri = 'https://localhost:49631/'

>>> # implicit
>>> cups_get_printers(uri)
[{}]
>>> # explicit
>>> cups_get_printers(uri, requested_attributes='all')
[{}]

Performing the request repeatedly will eventually bring the sought results. Perhaps the problem is with the ipptool. Needs further investigations.

Implement form for pause_printer function

Implement form for resume_printer function

prevent infinite looping, when credentials are wrong

create_printer_subscription -- TypeError: unsupported operand type(s) for +: 'float' and 'str'

Configuration values which are expected to be integers or floats can be fetched using the getint and getfloat methods, respectively.

>>> create_printer_subscription('https://localhost:49631/', printer_uri='https://localhost:49631/printers/gluino', requesting_user_name='ecp_admin', notify_recipient_uri='ezpnotifier://')

cups_add_modify_printer/class: support printer-op-policy

Prevent blocking subprocess

ipptool might prompt user for credentials if they are missing. Thus blocking forever the subprocess call.
1 - We need to implement a timeout

Write integration test for cups_add_modify_printer

NOTE: the test is already written, but the addition of the printer does not work. So it is in a "troubleshooting" phase.

KeyError: 'notify-subscription-id' for create_printer_subscription response

def create_printer_subscription(uri, ...):
    # ...
    return response['Tests'][0]['notify-subscription-id']

the return value should be changed to

return response['Tests'][0]['ResponseAttributes'][1]['notify-subscription-id']

seems not possible to pass string values for printer_state parameter

• function: cups_add_modify_printer
• parameter: printer_state
• problem: at the moment, only integers can be passed; for instance if setting the printer in 'idle' mode, then the integer 3 has to be passed - passing the string 'idle' won't work

Implement CUPS-Get-PPD Operation

See specifications at http://www.cups.org/documentation.php/doc-1.7/spec-ipp.html#CUPS_GET_PPD

Implement forms for the Hold-New-Jobs & Release-Held-New-Jobs operations

Release for py3 support

Any chance for a release that updates the package on pypi to include support for py3?

Implement tests for the Hold-New-Jobs & Release-Held-New-Jobs operations

SyntaxWarning : assertion is always true ...

Begin writing CUPS-based integration tests

fitplot / fit to page / scaling

There doesn't seem to be any way to pass the cups fitplot / fit-to-page / scaling option in the print_job function

get_subscriptions parameters should be as in rfc 3995

see specs at http://tools.ietf.org/html/rfc3995#section-11.2.5

11.2.5.1. Get-Subscriptions Request

The following groups of attributes are part of the Get-Subscriptions
request:

Group 1: Operation Attributes

Natural Language and Character Set:
...
Target:
The "printer-uri" attribute which defines the target for this
operation as described in [RFC2911] section 3.1.5.

Requesting User Name:
The "requesting-user-name" attribute SHOULD be supplied by the
client as described in [RFC2911] section 8.3.

11.2.5.1.1. "notify-job-id" (integer(1:MAX))
...
11.2.5.1.2. "limit" (integer(1:MAX))
...
11.2.5.1.3. "requested-attributes" (1setOf type2 keyword)
...
11.2.5.1.4. "my-subscriptions" (boolean)
...

Add Tornado support

Add tornado support for non-blocking subprocess calls

Review code for CUPS-Add-Modify-Class Request

1. Add support for the member-uris argument

think of a more convenient way to pass requested attributes

For instance:

when requesting the attributes of a printer, if one wishes to only retrieve the name and state, the current way will be:

requested_attributes = 'printer-name,printer-state'
get_printer_attributes(uri, printer_uri=printer_uri, requested_attributes=requested_attributes)

one approach that would perhaps be more convenient would be the possibility to pass the requested attributes as a tuple, or list ...

requested_attributes = ('printer-name' , 'printer-state')
get_printer_attributes(uri, printer_uri=printer_uri, requested_attributes=requested_attributes)

we would then internally convert the list/tuple into a string ...

def get_printer_attributes(uri,
                           printer_uri=None,
                           requesting_user_name=colander.null,
                           requested_attributes=colander.null):
    if requested_attributes:
        requested_attributes = ','.join(requested_attributes)
    # ...    

thus allowing users of the function to simply pass a list/tuple for the attributes they wish to retrieve

this obviously requires the user to properly use the function, meaning that passing a string won't work, for instance ...

py37 support

Support octetString type

see section 4.1.10 in http://tools.ietf.org/search/rfc2911#section-4

it is used in create subscription operations for the field notify-user-data
