Thermal printer can not printing test

Post by xhxhxh555 »

Hi, I buy a thermal printer use RS232 interface. But it don't printing test. I press button long time but printer no printing test( no working). I press button then the paper rolls out for about 10mm and stops. I check paper is right. When I supply power, led green is on. I using supply power change and increase voltage from 5 to 9 V, current supplies is 3A but no working?.
