If a Windows® driver is WHCL-signed, or a Mac® driver is packaged in a standard format, then generally speaking it can be uploaded into LRS CloudPrint for use with printers. For Windows, most self-extracting archive and Zip formats are supported, but occasionally we encounter a package which can't be unpacked in the cloud following upload. In that case, a clear message is displayed and instructions are provided in the on-line documentation for extracting and re-packaging 'difficult' drivers.
