We have noticed an issue with several brands of printers, including the Star TSP100 series printers, when printing from Windows 10 PCs that have recently been updated via the Windows Update Service. The most common symptom is that print jobs are sent but do not actually print. More information on which printer models are affected and which updates are involved can be found via the following link: For customers using Windows 10 and Windows Server and Star printers with USB interface
To help you get back on your feet quickly, Star Micronics has published an online support page that explains how to fix the problem. This page will be updated as more information and support resources from Microsoft become available. You can find this support page via the following link: Star USB Printers & Star TSP100 Series with Windows Updates
