Citrix Printing Series - Print Job Routing

In a XenDesktop/XenApp environment, print jobs can take two routes, they are:

  • Through the client
  • Through a network print server

When locally attached printers are used, print jobs are routed through the ICA channel and are compressed. When Client printers are used, the print job must be routed through the client.

When network based printers are used, print jobs are routed directly from the XenApp server to the printer. Print jobs can be routed through the client for network based printers if there are trust issues or the driver is not available. Printing using this method results in uncompressed traffic .

The Direct connections to print servers policy can be used to configure servers and virtual desktops to print directly to print servers. If this setting is misconfigured, the print job may traverse the WAN 3 times!

  • Print Job sent to client via ICA
  • Print Job sent to Print Server, uncompressed
  • Print Job sent to Printer, uncompressed

Generally, when printing over a WAN it is ideal to have print jobs routed through the client, if this is not possible, or to provide additional control, configure QoS (and multi-stream ICA if required).

  1. I have had many of my customers ask me why we print their products using different methods at different times. This is a valid question and for the sake of educating the larger masses and for those that are interested I will outline the difference between the printing process and how they may apply to your project. There are generally four printing methods, they are screen printing, heat transfer press, and embroidery "well this is not really printing but I place it there as you still need to place an image on a t shirt". The last and the latest technology is direct to garment. This process can produce some fantastic hi resolution photographic printing but it is at a cost. Printing East London
