Abstract

컴퓨터와 프린터 간의 신호전송을 가능하게 하는 무선프린터용 어댑터가 고안된다. 상기 무선프린터용 어댑터는 무선 연결통로를 통하여 컴퓨터로부터 상기 프린터에 또는 그 반대로 신호를 전송하기 위한 무선수단을 채용하여 케이블의 사용을 배제하므로서 컴퓨터와 프린터의 사용을 더 편리하게 한다.Adapters for wireless printers are conceivable which enable signal transmission between a computer and a printer. The wireless printer adapter makes use of a computer and a printer more convenient by employing a wireless means for transmitting signals from a computer to the printer or vice versa via a wireless connection path, thereby eliminating the use of cables.

Description
