An updated print server for Check-In is available. After a few weeks of successful beta testing, version 1.1.3 is now ready for general release. This newest version eliminates the five-second delay of previous versions and, like the most recent previous version (1.0.4), can be run as a system service. Or, if you prefer, it can still be run as a standalone application.
If you have 1.0.4 installed as a system service, the upgrade to 1.1.3 will be automatic. If you currently have a version earlier than 1.0.4 installed or are running 1.0.4 as a standalone application, you will need to manually upgrade to the newest version. To do this, follow the installation instruction in this help article, where you can also read more about the Check-In Print Server.
