There is no persistent workspace for users of virtual desktops and applications. You can customize how to perform these tasks by configuring options for printer provisioning, print job routing, printer property retention, and driver management.

Be sure to evaluate how the various option settings might change the performance of printing in your environment and the user experience. The process that makes printers available in a session is known as provisioning. Printer provisioning is typically handled dynamically. That is, the printers that appear in a session are not predetermined and stored.

Instead, the printers are assembled, based on policies, as the session is built during log on and reconnection. As a result, the printers can change according to policy, user location, and network changes, provided they are reflected in policies. Thus, users who roam to a different location might see changes to their workspace. The system also monitors client-side printers and dynamically adjusts in-session auto-created printers based on additions, deletions, and changes to the client-side printers.

This dynamic printer discovery benefits mobile users as they connect from various devices. Citrix recommends the Citrix Universal Print Server for remote print server scenarios. The Universal Print Server transfers the print job over the network in an optimized and compressed format, thus minimizing network use and improving the user experience.

A server component, UPServer - Install UPServer on each print server that provisions session network printers and uses the Universal print driver for the session printers whether or not the session printers are centrally provisioned.

For Universal Print Server requirements and setup details, refer to the system requirements and installation articles. The following illustration shows the typical workflow for a network based printer in an environment that uses Universal Print Server.

When you enable the Citrix Universal Print Server, all connected network printers leverage it automatically through auto-discovery. Autocreation - Autocreation refers to printers automatically created at the beginning of each session.

Both remote network printers and locally attached client printers can be auto-created. Consider auto-creating only the default client printer for environments with a large number of printers per user. Minimizing auto-created printers can also reduce user logon times. Autocreation policy settings enable you to limit the number or type of printers that are auto-created. By default, the printers are available in sessions when configuring all printers on the user device automatically, including locally attached and network printers.

Client and network printer autocreation has associated maintenance. For example, adding a printer requires that you:. The term printing pathway encompasses both the path by which print jobs are routed and the location where print jobs are spooled.

Both aspects of this concept are important. Routing affects network traffic. Spooling affects utilization of local resources on the device that processes the job. In this environment, print jobs can take two paths to a printing device: through the client or through a network print server. Those paths are referred to as the client printing pathway and the network printing pathway.

Which path is chosen by default depends on the kind of printer used. The system routes jobs to locally attached printers from the Multi-session OS machine, through the client, and then to the print device. The ICA protocol optimizes and compresses the print job traffic. When a printing device is attached locally to the user device, print jobs are routed over the ICA virtual channel.

By default, all print jobs destined for network printers route from the Multi-session OS machine, across the network, and directly to the print server.

However, print jobs are automatically routed over the ICA connection in the following situations:. If the Universal Print Server is not enabled, configuring the client printing pathway for network printing is useful for low bandwidth connections, such as wide area networks, that can benefit from the optimization and traffic compression that results from sending jobs over the ICA connection.

The client printing pathway also lets you limit traffic or restrict bandwidth allocated for print jobs. The Citrix UPD consists of two components:. Server component. The PDF printer driver is now always installed automatically. When you upgrade to the 7. When a print job is initiated the driver records the output of the application and sends it, without any modification to the end-point device. Client component. It fetches the incoming print stream for the Citrix Virtual Apps and Desktops session.

It then forwards the print stream to the local printing subsystem where the print job is rendered using the device specific printer drivers. The order in which Citrix UPD attempts to use the drivers can be changed using the Universal driver preference policy setting. These features are available if the native driver makes them available using the Microsoft Print Capability technology.

If non-standard keywords are used, the advanced printing features are not available using Citrix Universal print driver. The following illustration shows the Universal print driver components and a typical workflow for a printer locally attached to a device. When planning your driver management strategy, determine if you will support the Universal print driver, device-specific drivers, or both. If you support standard drivers, you must determine:.

During printer autocreation, if the system detects a new local printer connected to a user device, it checks the Multi-session OS machine for the required printer driver. By default, if a Windows-native driver is not available, the system uses the Universal print driver. The printer driver on the Multi-session OS machine and the driver on the user device must match for printing to succeed.

The illustration that follows shows how a printer driver is used in two places for client printing.
