Abstract: The present disclosure provides a system and method of universal cloud printing that unites perspectives of both servers and printers in cloud-based printing. Using printer metadata and explicit constraints allows the server to accommodate various types of printers. Payloads can be consistently printed across various printers having different manufacturers, specifications, formats, or features. Status codes from the printer are defined and initiate a responsive action from the server.

Abstract: A method for conditioning a building includes drawing unconditioned outside air at a first flow rate through a dedicated outdoor air system unit, conditioning the outside air by the dedicated outdoor air system unit to conditioned air, supplying the conditioned air to a first room, and exhausting the conditioned air at a second flow rate to an exterior of the building by a kitchen exhaust fan located in a second room. The first and second rooms can be in fluid communication with a common area of the building such that the conditioned air from the first room is drawn to the second room via the common area to supply conditioned air to the common area and second room. The second flow rate can be controlled by a temperature sensor adjacent the kitchen exhaust fan.

Abstract: The present disclosure describes a queued message service (QMS) that provides a multi-region, low-latency and reliable service for managing a large number of durable message queues for async targeted communication. This general-purpose, internal service QMS may be implemented in print queues as well as command queues for sensors. One example implementation of QMS is a print service. Such implementation introduces status indicators for printers internally, wherein such status indicators may identify whether a printer is blocked, offline, suspected of failure, properly functioning, etc.

Abstract: This present disclosure provides for a work distribution service, which is a multi-region, reliable service for dynamically sharding key ranges. The work distribution service offers exclusive ownership with leases, load balancing and routing information for owner discovery. Using the work distribution service, services can easily scale horizontally by sharding their workloads.
