Abstract: Example methods and systems to implement an economic printing mode are described. In one example, a computer system may provide a user interface specifying multiple selectable levels associated with economic printing mode. The source printing content may be transformed to generate target printing content that is printable using a lower ink consumption compared to the source printing content. For example, in response to a selection of a first level, print quality may be reduced. In response to a selection of a second level, image information in the source printing content may be modified. In response to a selection of a third level, font information associated with textual information in the source printing content may be modified. The computer system may provide the target printing content that includes modified font information to the printer for printing and/or generate a preview of the target printing content prior to printing using the printer.

Abstract: The disclosure provides an approach for print redirection in a remote computing environment. Embodiments include receiving, on a remote device, a request to perform a printing task using a printing device associated with a client device. Embodiments include determining, on the remote device, that data associated with the request to perform the printing task exceeds a size threshold. Embodiments include generating, on the remote device, a plurality of data slices based on the data, wherein each respective data slice of the plurality of data slices comprises a respective subset of the data that does not exceed the size threshold. Embodiments include transmitting, from the remote device to the client device, the plurality of data slices as separate transmissions in separate time intervals along with information that allows the data to be reconstructed from the plurality of data slices for performing the printing task on the client device.

Abstract: A print driver store is usable for redirection printing in a virtualized computing environment that supports virtual desktops. Native print drivers are uploaded to the print driver store from a client side. When an agent attempts to instantiate a virtual printer at the agent side that corresponds to a physical printer at the client side, the agent checks to determine if a native print driver for the physical printer is installed at the agent side. If the native print driver is not installed, then the agent obtains the native print driver from the print driver store and installs the native print driver at the agent side. The agent completes the instantiation of the virtual printer at the agent side and associates the native print driver with the virtual printer.

Abstract: A varied least recently used (VLRU) caching technique is used to enable print data to be available at a cache of a client for printing, even after an agent performs a deletion of a hash value for the print data at a cache of the agent. The deletion of the print data (cached at the cache of the client) is postponed at the client device via the use of a waiting list, so that the cached print data can be printed at a physical printer of the client, in response to receiving a delayed print job from the agent that specifies the hash value as a result of a deduplication process performed by the agent.

Abstract: Example methods and systems are described to add a watermark for printing in a virtual desktop environment having an agent side and a client side. A watermark can be configured at the agent side for printing at the client side. At the agent side, a fallback font can be determined for text of the watermark, and coordinate space calculation can be performed, so that the watermark prints correctly at the client side.
