The correct answer is B. Disable direct connections to the print server. Slow branch office printing occurs because print jobs travel over the WAN from the London VDA directly to the branch print server; disabling direct connections routes print traffic through the already QoS-optimized ICA channel instead.
Question
Scenario: An organization has headquarters based in London and has branch offices in New York and Beijing. Citrix XenDesktop was recently implemented in the environment. All Desktop OS machines are located within the London Datacenter while print servers are located in each branch office. Users have been complaining that printing from the branch offices is slow. All branches are connected through a Wide Area Network (WAN). QoS has been implemented for all ICA/HDX traffic. How could a Citrix Administrator optimize the printing performance for branch office users without asking for additional investments from management?
Options
- ADisable client auto-created printers.
- BDisable direct connections to the print server.
- CIncrease the WAN link speed to the branch offices.
- DAdjust printing bandwidth as part of the overall user session bandwidth limit.

Why each option
Slow branch office printing occurs because print jobs travel over the WAN from the London VDA directly to the branch print server; disabling direct connections routes print traffic through the already QoS-optimized ICA channel instead.
Disabling client auto-created printers removes printer availability for branch users entirely rather than addressing the underlying WAN routing inefficiency.
When direct connections to the print server are enabled, the VDA in London establishes a direct network path to the branch print server, sending all print data across the WAN outside of the ICA channel and bypassing the existing QoS policy. Disabling direct connections forces print jobs to travel through the ICA/HDX virtual channel, where they are received by the client endpoint in the branch and delivered locally to the nearby print server. This eliminates the WAN round-trip for print data and leverages the existing QoS configuration, improving performance without additional cost.
Increasing the WAN link speed requires a financial investment in upgraded circuits, which directly violates the constraint of not requesting additional budget from management.
Adjusting printing bandwidth within the session limit throttles available print throughput rather than resolving the inefficient WAN routing that is the root cause of slowness.
