Since version 10.0.5.

If a job is being sent from the neoStampa Print dialog to a local Print Server and the latter is not running, the following alert is shown when clicking on the Print button.

Close the alert window so the Print dialog is opened, which has a button to start the Print Server process for the printer driver currently loaded on neoStampa. Just click on that button, wait on Print Server to open, and send the job again.
