问题描述
我想打开一个现金抽屉，我购买了它的打印机驱动的现金抽屉.我有一台 Epson TM-T81 收据打印机.
I want to open a cash drawer which I have bought its printer driven cash drawer. And I have an Epson TM-T81 receipt printer.
当我手动打开和关闭打印机时，我收到一个委托，但我想在打印收据时自动打开它.
I get a delegate called when I open and close the printer manually but I want to open it automatically when receipt is printed.
我写的代码是:
-(void)openDrawer{
EposBuilder *builder = [[EposBuilder alloc] initWithPrinterModel:@"TM-P20" Lang:0];
if(builder == nil){
return ;
}
//add command
int result;
result = [builder addPulse:EPOS_OC_DRAWER_1 Time:EPOS_OC_PULSE_100];
NSLog(@"%d command result",result);
NSString *str = @"27 112 48 55 121";
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
result = [builder addCommand:data];
NSLog(@"%d pulse",result);
if(result != EPOS_OC_SUCCESS){
NSLog(@"cut failed");
return ;
}
//send builder data
unsigned long status = 0;
unsigned long battery = 0;
result = [printer sendData:builder Timeout:10000 Status:&status Battery:&battery];
//remove builder
[builder clearCommandBuffer];
}
