  • Print jobs through primos stay in the company network and do not get transferred via internet or other cloud mechanisms. All print jobs are secure with point-to-point encryption. During the entire transfer from iOS device via primos to the printer, the data is encrpyted. This ensures that sensitive information can neither be read nor changed during the entire process. With primos it doesn’t matter what kind of printer you have, its brand, nor whether it is AirPrint capable or not. You just print directly over the network. It doesn’t matter whether you are in your office, in a meeting or in a colleague’s office: primos users can print company-wide not only in their own network but also in sub-networks via Wide Area AirPrintTM. With primos you are able to connect to and print from up to 10 network printers (including 1 USB printer).
