Print a hex file in java

Question

I would like to print a hex file on a receipt printer. For testing, I use the cmd with the command: "copy /b test.hex lpt3:"

Now I would like a java programm, which can send the test.hex to the printer, but not as graphic.

Please, can someone tell me, how I can do that?

Thanks in advance :D

first - what should this output look like? second - can you print this format to the screen? Do the latter, then figure out the former. — KevinDTimm, Feb 10 '12 at 13:26

I am not sure about the syntax inside the string anymore, but you can always look that up. In Principle you can do this:

Runtime.getRuntime().exec("cmd /c start copy /b test.hex lpt3:");

So if you find no way to access that custom printer directly from java you can first create that .hex file, then use exec() to send it.

I dont work often with Runtime, can you tell me the command for Close, after your commandline? I have try: 1. Runtime.getRuntime().exec("cmd /c start copy /b test.hex lpt3:"); 2. Runtime.getRuntime().exec("cmd /c stop"); – FabianG Feb 10 '12 at 14:03
close? i dont understand what you want to close. – Bernd Elkemann Feb 10 '12 at 14:16
ahh, the dos-box stays open. i previously only tried `Runtime.getRuntime().exec("cmd /c start explorer");` In which case there is no dos-box. Let me try something to get that dos-box closed again... – Bernd Elkemann Feb 10 '12 at 14:18
`String[] commands = new String[2]; commands[0] = "cmd /c start copy a.java b.java"; commands[1] = "cmd /c start exit"; Runtime.getRuntime().exec(commands);` – Bernd Elkemann Feb 10 '12 at 14:23
Sure! And thanks for accepting the answer although you have to construct it yourself from the answer and the additional comment. – Bernd Elkemann Feb 11 '12 at 10:03
