The Pharos Popup Client module is not part of the package. Add this module in Pharos Administrator (Package Definitions > Pharos Supplied Modules), rebuild the package and distribute. The problem could also be related to the following issue

 

- Check to see if you installed the Print Services for Unix on the workstation
- Then check the port to see if it was created using LPR, if so does the port name start with name Pharos

 

LPR port with the name starting with Pharos also causes the same error message

 

Example
PHAROS72:test1_q
