Applications Appear to be Unresponsive During Session Launch because of Inaccessible Print Servers or Orphaned Printers

Symptoms

Applications appear to be unresponsive during session launch because of inaccessible print servers or orphaned printers.

Cause

Most users have Network Printers defined on their computers while at the work place. If the same users now bring their computers home (typically a laptop) these printers although still defined on the user’s machine are no longer available because the print server is not reachable from the user’s home network.

So if the user then makes an ICA connection from home to the workplace XenApp picks up these printers and tries to make them available for their session.

Because these printers are in an offline or unavailable state it can cause the loading of the session to be delayed for 15 seconds or more depending on how many Network Printers are defined on the user’s computer.
