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 methods are provided for improved directory enumeration and data copy with shared client directories in virtual desktops by quickly and efficiently retrieving shared directory entries from the client device over a separate fast channel and caching them on the virtual desktop, where the directory entries can be available locally to applications in the virtual desktop for performing directory enumeration. The fast channel can further be utilized for efficiently transferring data in data copy operations between the client device and the virtual desktop.

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: Techniques are described for enabling printer redirection in virtual desktop environments that provides a font processing system including a session-based font cache subsystem. The system resolves any font mismatching issues that might arise in the context of printing on a virtual desktop from virtual desktop client devices in an optimized manner that reduces latency and generally improves performance during printer redirection. The session-based font cache is used to accelerate the font processing and to reduce the transmitted font data between the virtual desktop agent and the virtual desktop client in the context printer redirection.
