![]() This can apply to network-based printers, but in most cases, it is an issue with the network communication. ![]() If the print jobs from users are spooled but never appear at the printer and the end user is connecting to the Citrix environment using a VPN-based access with force tunneling, this might "timeout" the connection to the local printers. Admins should check if the native drivers have the option to do this or use client printer redirection if possible. If the driver does not use nonstandard keywords, the advanced printing features are not available with Citrix Universal print driver. The native driver should use the standardized Print Schema Keywords in the Print Capabilities XML. These features are available in the session if the native driver makes them available using the Microsoft Print Capabilities technology. Citrix Universal Print Driver (UPD), Enhanced Metafile (EMF) or XML Paper Specification (XPS) drivers should support these advanced printing features. Wrong configuration on the printerĮnd users often prefer to configure settings on the printer in terms of how the printer should print, such as if it should use double-sided, colors and which drawer it should print from. ![]() IT should check the NetScaler to ensure that it is properly configured in terms of using enlightened data transport (EDT) as transport protocol or using the proper transmission control protocol (TCP) profile on the NetScaler.Īdmins should also ensure that the print drivers are using printer control language ( PCL)6-based drivers, because they have a better compression rate of spooled jobs than PCL5-based drivers. User sessions with high latency and high amount of packet drops will also affect the performance of printing. Check Citrix Director for printer information such as bandwidth, policies or configuration. IT pros should first access Citrix Director to see if there are any policies in place or to see what kind of latency the connected users are experiencing. Since printing is also supported in double-hop scenarios, the Gateway can be the root of the Citrix printing issue if it has limited bandwidth or the wrong configuration. Slow printing can occur if IT has a quality of service (QoS) policy in place that limits the amount of bandwidth that is available per session, or if users have enough bandwidth available on the Gateway. Like most Citrix features, printing has its own virtual channel in the independent computing architecture (ICA)/ high definition experience ( HDX) protocol stack. IT pros should learn about these five common Citrix printing issues and how to address them. When they do, IT pros should find the right troubleshooting process. Still, it's common for VDI admins to face Citrix printing issues.
