ESC/POS command not working. #12

Hi, thank you for this great library. It works perfectly with an old china-made printer (GPrinter_399B) using printText method. However, printPOSCommand doesn't seems to work. i've tried printing "0A" (line feed), the console log shows "Data Sent", but the printer does nothing.

i've managed to do a line-feed by adding \n (new line) at the end of the string, so it looks like "0A\n". and the printer does the line-feed. i don't know whether it's the 0A command is working or because the \n character which does the line feed.

The POS commands, must be separated in my understanding, for example to skip 2 lines and give 2 feeds on paper, I use and it works like this:

BTPrinter.printPOSCommand(null, null, "0A");//Print and feed paper BTPrinter.printPOSCommand(null, null, "0A");//Print and feed paper
