Abstract

A method for printing a document from a mobile device includes identifying a document to be printed and generating a notification comprising a selection of at least one candidate print device that may be selected for printing. The notification may be generated by analyzing, by one or more mobile device applications, the document to be printed to identify a document context including a security level of the identified document; using data sensed by one or more mobile device sensors to identify a user context including at least a current geographical location of the user; using the user context to detect a print device near the geographical location of the user; and accessing a rule set to determine if the identified document can be printed on the detected print device based on the security level of the identified document; and causing a user interface to output the notification.

First claim

The invention claimed is:

1. A method of printing a document from a mobile device comprising:
by a processor of the mobile device executing a print application that causes the processor to:
identify a document to be printed,
generate a notification comprising a selection of at least one candidate print device that may be selected for printing the document by:
using data obtained from the mobile device to identify:
a document context that specifies a context corresponding to the identified document, and
a user context,

wherein the data obtained from the mobile device comprises one or more of the following:
data sensed by one or more sensors of the mobile device, or
data gathered by one or more mobile applications of the mobile device,

using the user context to detect a print device,
using at least the document context to determine if the document can be printed on the detected print device,
saving the document and the document context associated with the document to a client print queue, if the document cannot be printed on the print device,
detecting, by a location sensor of the mobile device, a change in location of the mobile device,
updating the user context to a new user context based on the change in location,
using the new user context to detect a first print device,
for each document in the client print queue, determining whether the document can be printed on the first print device using at least a document context associated with the document,
including the first print device and an identification of at least one document that can be printed on the first print device in the selection of at least one candidate print device, and
causing a user interface to output the notification.

2. The method of claim 1 , further comprising:
obtaining print device data at the mobile device;
using the print device to identify print device context associated with the detected print device; and
using the print device context to determine if the document can be printed on the detected print device.

3. The method of claim 2 , wherein identifying the print device context comprises identifying print device context information relating to at least one of the following:
information relating to one or more capabilities of the print device;
a geographical location of the print device;
user print history data corresponding to the print device;
information relating to one or more print device connectivity settings; or
print device network information.

4. The method of claim 3 , wherein using the print device context to determine if the document can be printed on the detected print device comprises using the information relating to one or more capabilities of the print device to determine whether the print device is capable of printing the document.

5. The method of claim 4 , wherein using the print device context to determine if the document can be printed on the detected print device further comprises determining whether the document context allows the document to be printed at:
the geographical location of the print device; or
within a network of the print device.

6. The method of claim 1 , wherein identifying the document context comprises identifying context information relating to at least one of the following:
an intended use of the document,
a location of the document in the mobile device,
a type of the document,
metadata associated with the document, or
at least one keyword in the document.

7. The method of claim 6 , wherein identifying the document context further comprises using the identified context information for identifying a security level and a printing policy for the document.

8. The method of claim 7 , wherein using at least the document context to determine if the document can be printed on the detected print device comprises using the identified security level and the identified printing policy to determine if the document can be printed on the detected print device.

9. The method of claim 7 , wherein identifying the document context further comprises identifying the document context using previous user selection or preferences.

10. The method of claim 1 , wherein identifying the user context comprises identifying a location of the user based on context information relating to at least one of the following:
a geographical location of the user,
user preference information,
user print history data,
user profile, or
user identity.

11. The method of claim 10 , wherein identifying context information relating to a geographical location of the mobile device comprises at least one of the following:
using one or more location tracking sensors of the mobile device to sense the location of the mobile device, or
receiving data from a calendar application of the mobile device and using the data to identify the location of the mobile device.

12. The method of claim 11 , wherein using the one or more location tracking sensors to sense the location of the mobile device comprises at least one of the following:
using data captured by a positional sensor of the mobile device to detect the location of the mobile electronic device,
using an identifier of a network to which the mobile device is connected, or
using a micro-location technique of the mobile device.

13. The method of claim 12 , using the user context to detect a print device comprises using the identified location of the user to determine if one or more devices exist within a predetermined distance of the identified location of the user.

14. A system for printing a document from a mobile device comprising:
a non-transitory, computer readable memory;
one or more processors; and
a computer-readable medium containing programming instructions that, when executed by the one or more processors, cause the system to:
identify a document to be printed, and
generate a notification comprising a selection of at least one candidate print device that may be selected for printing the document by:
using data obtained from the mobile device to identify:
a document context that specifies a context corresponding to the identified document, and
a user context,

wherein the data obtained from the mobile device comprises one or more of the following:
data sensed by one or more sensors of the mobile device, or
data gathered by one or more mobile applications of the mobile device,

using the user context to detect a print device,
using at least the document context to determine if the document can be printed on the detected print device,
saving the document and the document context associated with the document to a client print queue, if the document cannot be printed on the print device,
detecting, by a location sensor of the mobile device, a change in location of the mobile device,
updating the user context to a new user context based on the change in location,
using the new user context to detect a first print device,
for each document in the client print queue, determining whether the document can be printed on the first print device using at least a document context associated with the document,
including the first print device and an identification of at least one document that can be printed on the first print device in the selection of at least one candidate print device, and
causing a user interface to output the notification.

15. The system of claim 14 , further comprising programming instructions, that when by the one or more processors, cause the system to:
obtain print device data at the mobile device;
use the print device to identify print device context associated with the
