Epson epos sdk receipt alignment issue
Tag : java , By : Gilmar Souza Jr.

wish help you to fix your issue 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) , 80mm is like 42 columns per line ...which can be easily padded:
mPrinter.addText(padLine(menuName, price + "¥", 42) + "\n");
/** utility: pads two strings to columns per line */
protected String padLine(@Nullable String partOne, @Nullable String partTwo, int columnsPerLine){
    if(partOne == null) {partOne = "";}
    if(partTwo == null) {partTwo = "";}
    String concat;
    if((partOne.length() + partTwo.length()) > columnsPerLine) {
        concat = partOne + " " + partTwo;
    } else {
        int padding = columnsPerLine - (partOne.length() + partTwo.length());
        concat = partOne + repeat(" ", padding) + partTwo;
    }
    return concat;
}

/** utility: string repeat */
protected String repeat(String str, int i){
    return new String(new char[i]).replace("\0", str);
}
