Scenario: The Help Dest team is troubleshooting a printing issue. Users connect to print servers located in two different datacenters. The print…

The scenario indicates that only Citrix-related traffic (ICA/HDX) is permitted between the two datacenters. Standard Windows printing from a Virtual Delivery Agent (VDA) to a network print server establishes a direct connection using protocols like RPC, which would be blocked by this network rule. The Citrix Universal Print Server (UPS) is designed to solve this by routing print jobs over the ICA/HDX virtual channel. By implementing a Citrix policy that disables direct connections to the print servers, the administrator forces the print traffic to be proxied through the VDA and encapsulated within the allowed ICA/HDX protocol. This ensures the print job can reach the remote print server across the restricted network.

A. Limiting printing bandwidth is a performance optimization and does not resolve the underlying network connectivity issue that is blocking the print job entirely.
C. Installing Universal Printer Drivers is a component of the overall printing solution, but it does not, by itself, change the network routing path of the print job.
D. Auto-creating printers is a policy that determines how printers are mapped into a user session; it does not affect the network protocol used for communication.

1. Citrix Virtual Apps and Desktops Documentation - Universal Print Server: "The Universal Print Server enables printing to network printers from a WAN. This functionality is for network printers in locations that are separated from the VDAs by a WAN... The print data is sent from the VDA over the ICA protocol to the Universal Print Server, which then spools the job to the target printer using the native driver." This confirms that UPS routes traffic over the ICA protocol, bypassing the need for a direct connection.

2. Citrix Virtual Apps and Desktops Documentation - Universal Print Server policy settings: The "Universal Print Server enable" policy is central to this solution. When enabled, it forces printing through the UPS path. A sub-setting, "Enable fallback to Windows' native remote printing," can be disabled to prevent any attempt at a direct connection, which aligns with the action described in the correct answer.
