Cannot print labels from Web Applications in Control Center, or cannot access Document Storage from the clients

Official translation unavailable. Translate this page with Google:


When you want to print labels from Web applications in Control Center, the procedure fails and no labels print out. You also cannot get any file (label, solution, image) from Document Storage.

You may see the following message when you use Web printing:

An error occurred while getting variables from the label: Label file cannot be opened.

The problem causes the old version of WebDAV (support for Web folders). During the installation of NiceLabel Control Center, the installer verifies the current version WebDAV files and prompts you to make the upgrade if the version is too old. You didn't make the necessary update and that makes the Document Storage (and consecutively Web printing) inaccessible.


You must install WebDAV support on all clients that need to have access to the Document Storage. This includes workstations with NiceLabel PowerForms, Automation, and the Control Center computer itself (if you plan to use Web applications).
