parameter is indeed there in the requestSmall details need to be reviewed. See Create-Printer-Subscriptions Request and more particularly Subscription Template Attributes.
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..

Performing the request repeatedly will eventually bring the sought results. Perhaps the problem is with the ipptool
. Needs further investigations.
Configuration values which are expected to be integers or floats can be fetched using the getint and getfloat methods, respectively.

ipptool might prompt user for credentials if they are missing. Thus blocking forever the subprocess call.

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

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

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))

Add tornado support for non-blocking subprocess calls
member-uris
argumentFor 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 ...
