Array.prototype.map() function can be a little tricky, use for(let i=0;i<arrays.length;i++){...} instead. Or you may try to figure out "this" ref and "BluetoothEscposPrinter" whether still works at "item=>{}" scope.
我对Array.prototype.map()不是太熟悉,因为从来不用这个奇怪的东西,他本身就不保证执行顺序,对this引用又很依赖你编译的结果,所以可以使用两种map()的写法来测试一下到底什么问题。基本上这些要求顺序的遍历,我只会用for(let i=0;i<arrays.length;i++){...} 来处理。
