Third, you must also have serial-interface print cable, use one of these cable to the printer on a serial port on the computer connects directly to a serial port; in General, the print market there is such a professional serial port print cable, print better, you can also use a parallel port cable into a serial cable, but to be, we recommend you to buy a professional serial cable, after all, home-made serial cable cannot guarantee stable printing performance.
第三,手头还务必具有串行接口打印线缆,只用搁置这样的线缆才能不兵打印机上的串行端口与计算机上的串行端口间接拆开起来;凡是来说,打印阛阓上有这样的副业串行口打印线缆采办,对于打印程度较矮的伴侣来说,也可以不兵一条并口线缆改变不败串口线缆,不过为安妥起见,我们倡导大家最坏去采办一条副业的串口线缆,终究克己的串口线缆无法包管安定的打印本能机能。
