How To: Easily Evaluate and Permanently Operate Apps with Appliances

IT environments are a dynamic situation with changing problematics, requirements and needs of users. System administrators have to face these dynamics while maintaining IT operations.

In this article, we want to show how Univention App Appliances can help with this. As pre-configured virtual images ready for immediate use with an integrated operating system, they can be used to quickly try out new software, switch it off if it fails to deliver the desired results, or, if the evaluation is successful, transfer the test solution to live operation.

UCS: How to Connect your Printers

In this article with corresponding how to film we are going to explain how to connect printers in UCS. Univention Corporate Server offers a printing system that can be implemented even in complex environments. Printers and printer groups are managed in the Univention Management Console, UMC for short. The print services are based on CUPS – that’s the Common Unix Printing System. The printer queues are managed by CUPS and UMC.
PPD files (PostScript Printer Description) describe the technical capabilities of the printers. These files contain information about the printers’ features, i.e. whether it’s a color device, whether duplex printing is possible, which paper trays are available, which resolutions and which printer command languages are supported (e.g. PCL or PostScript). UCS provides a variety of PPD files, so most printers can be accessed and configured without having to install additional drivers. If you have to set up extra PPD files, please have a look at our manual.
