So I

问题 I'm working with a restaurant bill printing software. I've developed a receipt. but they don't look actually like a receipt. I've followed a solution from codeProject. Here is my code of building a receipt: //Get the Graphics object Graphics g = printTextEvArgs.Graphics; //Create a font Arial with size 16 Font font = new Font("Arial", 10); float fontHeight = font.GetHeight(); string underLine = "------------------------------------------"; int startX = 10; int startY = 10; int offset = 40; /

Is anyone able to perform Receipt validation?

问题 Is anyone now online able to perform receipt validation in a Mac application? Have you used the ASN generated files in the application? Are you able to produce a sample receipt by automatic popup of the iTunes authentication? 回答1: The best way I know to check receipts is by letting Receigen generate the code - different for each new version. It's probably more secure than what you can develop in a reasonable time. 回答2: I have it working, but i am using open source code to do it. Using this

问题 I am looking at connecting a thermal receipt printer to Google Open Print, is this possible? and if so are you aware of any thermal printers that I can purchase? The reason for the above is that I have a takeaway shop with an online store. When an order is placed the order then gets printed on an A4 Injet printer. This is wasting me lots of paper and ink, Ideally I'd like it do be done with a thermal printer. I know the website can work with this I just need to make sure I can get a thermal

问题 Ok, this is starting to seem like a bit of a hopeless situation so I might as well throw a question out there to see if I can get lucky. I have a star micronics TSP 143U receipt printer connected to a Lantronix xPrintServer Home Edition to enable AirPrinting to the receipt printer over the local network. 90% of the setup works perfectly -- I have a rails webapp that creates a receipt and formats it using a css print media query, the Star Printer gets plugged in via USB to the xPrintServer and

问题 I'm implementing an iOS app with non-renewing subscription. Not much relevant information was available online; so I seek your guidance. A use case which worries me the most is when a user purchased the subscription once and then immediately after purchase it again to extend the duration of service (see such scenario here). What if that user were to refund the first purchase, leaving the second one intact? Is this even possible in practice, or am I just too paranoid? Assuming the above case

How to improve speed with Receipt printer and ESC/POS commands in Java

由 独自空忆成欢 提交于 2019-12-05 15:07:03
I have an application that communicates with a thermal printer in Java and makes the thermal printer print receipts with a barcode/emphasis/different sizes and so forth using a Star tsp 100 Printer. I can make the program print exaclty what i like but the printer is very slow. I believe the reason is that I am using non-preferable way/method of sending the byte commands. public static void Command(byte[] bytes) throws Exception{ //The bytes array is the argument, consisting of a byte[] array such as //byte[] Emphasis = {0x1B, 0x45}; //Which gives the text boldness. //And Command(Emphasis); To

Validating appReceiptStoreURL Returning 21002 Status

I have created a class which handles the purchases on In-App Purchases and also the validating of receipts. A while ago I used to use the transactionReceipt property on an SKPaymentTransaction, but have updated my code a fair amount and now use appStoreReceiptURL on the [NSBundle mainBundle]. Basically it seems as though my receipt is being sent to Apple's server in an acceptable manner, but I keep getting the status code of 21002. In auto-renewable subscriptions I know that this means the receipt is not in an acceptable format, however I have no idea what this status means in regard to an in
