This is usually caused by the Print Client no longer running

To restart the print client do the following 

Click on the Start Menu (bottom left hand corner of the computer screen)

Scroll down to the Staff folder and click on it 

Scroll down again until you find Print Client (Network) - click this 

You should then see a little green icon appear near the clock and when you now print you should get the costing box shown once again 

If this does not solve the issue please create a ticket and our technician will attend to the issue as soon as possible
