OnPaper is the first direct printing application to secure your document printing without remote access: no cloud, no LAN, no external computer.
OnPaper prepare the printout image based on the user settings (paper size, format, resolution etc.) from your documents and make it available directly to any printer supporting the PTP (photo transfer) protocol.
Connect your smartphone to the printer via USB OTG and start printing.
No special printing driver is needed, not remote connection via WiFi or cloud mobile access. Keep your printing secure without sharing on the net.
