Text prints out of order
async _print(text) {
console.log(text)
await SunmiInnerPrinter.printOriginalText(text)
}
await SunmiInnerPrinter.setAlignment(1)
await SunmiInnerPrinter.setFontSize(22)
await this._print('Order Receipt\n')
await SunmiInnerPrinter.setAlignment(0)
await this._print('Order Placed : ' + receipt.orderPlaced + '\n')
await this._print('Order ID : ' + receipt.orderId + '\n')
await this._print('Order Status : ' + receipt.status + '\n')
await this._print('Supplier : ' + receipt.supplier + '\n')
await this._print('Fulfillment : ' + receipt.fulfillment + '\n')
await this._print('Payment Status : ' + receipt.paymentStatus + '\n')
await this._print('----------------------------------\n')
await this._print('PRODUCTS\n')
await receipt.products.forEach(async ele => {
let text = ele.detail.name + ' : \n'
let price = ele.price ? Utils.currencyFormat(ele.price, 15) : "R0.00"
let quantity = ele.quantity.toLocaleString()
quantity = _.padEnd(quantity, 17, ' ')
text = text + 'x ' + quantity + price + '\n'
await this._print(text)
});
await this._print('----------------------------------\n')
await this._print('Total : ' + total + '\n')
await this._print('----------------------------------\n')
await this._print('\n')
await this._print('\n')
await this._print('\n')
Sometimes the dashed line that is meant to be above total prints before the products have printed. this is intermittent. Sometimes it prints in correct order, but about half the time it doesn't.
Plz be care about the usage of foreach.

I am doing await foreach so it should be ok?
do you recommend some other method?
You may do some console log to find out the call orders. Foreach may not completely the same as for(;;).

thanks for checking :)
We've parked this issue for now and will revisit in near future
I had problems because I did not use await / async in a proper way. All functions for printing text, bitmap are callbacks I think.
