You have a .bin chipless firmware file but want to update your printer via USB using an .efu file, like a regular firmware update. While .bin files are raw firmware for EPROM programming, .efu files are packaged for user-friendly USB updates. Direct conversion from a raw .bin to a flashable .efu is complex. Your best bet is to find a reputable third-party provider (like Inkchip.net) that offers chipless firmware specifically in the .efu format for your printer model. Be cautious, as using unofficial firmware can void your warranty and carries a risk of "bricking" your printer if done incorrectly. Always follow instructions precisely and verify compatibility.
