epson

i'm currently using epson ePOS SDK for android. i need to print the receipt that menu name align to the left and its price align to the right in the same line but it doesn't work properly, my temporary solution is add some feed line to make its price align right, is it possible to have both text align left and right in the same line ? (Attachments below and please ignore question mark symbols) mPrinter.addTextAlign(Printer.ALIGN_LEFT); mPrinter.addFeedLine(0); textData.append(menuName); mPrinter.addText(textData.toString()); textData.delete(0, textData.length()); mPrinter.addFeedLine(0); /

I am currently printing receipt from my data when i print my receipt alignment data is not working properly i think that i should apply start index and end index to string because my product name length is different So i apply this code to check length of string here is screenshot of Receipt you can see in receipt alignment is wrong Here is my code to give alignment and receipt if ProductName.characters.count > 13 {let subStr = ProductName[ProductName.startIndex.advancedBy(0)... ProductName.characters.count(13)] strtext.appendString(String (format: "%@ %@ %@\n", sQuantity,subStr,s)) textData

The code snippet below makes use of OPOS .NET to open a POS printer for printing. It works fine when executed as part of a standalone application. When executed by a Windows Service the call to GetDevice(...) always returns null. explorer = new PosExplorer(); device_info = explorer.GetDevice(DeviceType.PosPrinter, PrinterName); printer = (PosPrinter)explorer.CreateInstance(device_info); printer.Open(); printer.Claim(1000); printer.DeviceEnabled = true; The printer happens to be an Epson TM-U220B. Is there a security issue that needs to be overcome before a service has access to POS devices?

I was working on implementing ESC/POS(Epson Standard Code for Point of Sale) on a Kitchen printer(Aclas KP71M). I have a user interface the the POS user enters its string in to the user interface and the strings entered by the user will be sent to the printer and the printer prints the data. The printer interface with the host computer using Ethernet(100M) using TCP/IP connection. I have managed to embed each of the necessary commands in to a C# method and I also take some sample code on server/client C# connection and tried to include that in to my connection. The problem I am facing right

I've been building a POS application for a restaurant/bar. The design part is done and for the past month I've been coding it. Everything works fine except now I need to print. I have to print to a receipt printer connected to the computer running the software and later I'll try to print in a remote printer like a kitchen one. I've searched for help in the matter only to find that the standard for printing in these types of printers is using POS for .NET. The thing is, this is now a bit outdated or at least it hasn't had any updates since a couple of years. There's a lot of questions being
