Abstract: The capability to print to a portable document format (PDF) file is provided in a virtualized computing environment that supports a virtual desktop infrastructure (VDI). Printing-related properties, of local printers coupled to a client device, are provided to a host, so that virtual printers at the host can be configured with the printing-related properties. A simulator may be provided at the host to receive the printing-related properties from the client device and to receive a query from a virtualized computing instance for the printing-related properties, instead of the query being directly sent to the client device.

Abstract: An electronic device may include components that emit and detect infrared light. For example, a head-mounted device may have optical modules that present images to a user's left and right eyes. Each optical module may have an infrared light-emitting diode that emits infrared light that illuminates an eye box at an infrared wavelength, and an infrared camera that captures an image from the eye box at the infrared wavelength. A low-reflectance coating may be applied to one or more electronic device housing walls to prevent interference with the infrared components or with the visibility for a user. In particular, the low-reflectance coating may be a low-visible-reflectance-and-low-infrared-reflectance coating that exhibits low-reflectance across both visible and infrared wavelengths. The low-reflectance coating may be formed from carbon nanotubes and at least one organic solvent with zero polarity to ensure a low volatile organic component in the coating.

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: The disclosure provides a method of associating thread identifiers (IDs) to input/output (I/O) requests in a remote computing environment. The method generally includes receiving, by a mini-filter on a remote device that is remote from a client device, a request from an application on the remote device to access resources at the client device, determining, by the mini-filter, a thread identifier (ID) associated with the request, the thread ID corresponding to an application thread of the application that generated the request, determining, by the mini-filter, one or more parameters of the request, and transmitting, by the mini-filter, to a redirection server process on the remote device, a message comprising the thread ID and the one or more parameters of the request, wherein the thread ID and the one or more parameters of the request are added to a cache maintained by the redirection server process.

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 a method for universal naming convention (UNC) path redirection between a local desktop and a remote desktop. The method generally includes selecting, by a client device in an internal network, via an application running on a remote desktop in an external network, to open a UNC path for a resource located in the internal network. A firewall restricts the external network to access the resource located in the internal network. The method generally includes receiving, at the client device, from the remote desktop, via a virtual channel between the external network and the client device in the internal network, a message indicating to open the UNC path. The method generally includes opening, by the client device, via a local application of the client device, the UNC path to access the resource located in the internal network.

Abstract: Techniques are described for auditing print content during printer redirection in a virtual desktop. The ability to audit redirected print content allows an organization to pre-define certain sensitive data and to track whether print redirection requests in the virtual desktop environment contain any such sensitive data. If such sensitive data is contained in a printer redirection request, a file is generated containing information about the sensitive data, as well as a watermark that encodes information about the printer redirection request, such the user identifier of the user who initiated the print request and a timestamp of when the print request occurred. The generated file is transmitted to one or more registered recipients.

Abstract: Example methods and systems to implement an economic printing mode with font information modification are described. In one example, a computer system may obtain source printing content associated with a print job that is destined for a printer and the economic printing mode may be selected for the print job. The computer system may extract, from the source printing content, (a) textual information to be printed and (b) font information associated with the textual information. 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 by modifying the font information associated with the textual information. 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: Example methods and systems for printing ink consumption estimation are described. In one example, a computer system may obtain printing content associated with a document that is printable using a printer. Based on the printing content, the computer system may generate an image representation of the document, wherein the image representation includes an array of multiple pixels associated with first color information from a first color space. Color conversion may be performed by converting (a) the first color information from the first color space to (b) second color information from a second color space associated with the printer. The computer system may estimate an amount of printing ink required for printing the document based on the second color information and provide the estimated amount of printing ink to a user via a user interface.

Abstract: System and method are described for copying and pasting files and folders between a client and a virtual desktop via clipboard redirection. A virtual desktop session can be established by the client on the virtual desktop. The user can copy a file or folder to the virtual desktop clipboard and a path corresponding to the file or folder can be stored in the virtual desktop clipboard in a path list. When the user ungrabs the agent or switches focus out of the virtual desktop to the client, the path list can be transferred to the client device and set into the client clipboard. Subsequently, a request can be received in the client device to paste the copied file or folder to a target location in the client device. In response to the request, the client device can retrieve the contents of the copied file or folder from the agent and the contents can be placed in the target location to complete the paste operation.
