I am using the StarIO SDK to print text to a receipt printer and I am trying to get a certain line of text larger than the rest. I have some help from their support but I can't really get it to go.

   -(void)print{

        NSMutableString *final=[NSMutableString stringWithFormat:@"-----"];

        [final appendFormat:@"\n\nLevel:%@ Section:%@ Row:%@ Seat:%@", [response_dict objectForKey:@"level"], [response_dict objectForKey:@"section"],[response_dict objectForKey:@"row"],[response_dict objectForKey:@"seat"]];

There is a bunch of other stuff that is printing, but that is the line that I would like to be a different size than the rest. The StarIO support said that I should try and pass that to this...

-(IBAction)PrintText
{
    NSString *portName = [IOS_SDKViewController getPortName];
    NSString *portSettings = [IOS_SDKViewController getPortSettings];

    [PrinterFunctions PrintTextWithPortname:portName portSettings:portSettings heightExpansion:heightExpansion widthExpansion:widthExpansion textData:textData textDataSize:[textNSData length]];

    free(textData);
}

Would love some help if possible. :) Thanks so much.

This is the main bit I think I would need from the StarIO Text formatting doc...

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        array_hieghtExpansion = [[NSMutableArray alloc] init];
        [array_hieghtExpansion addObject:@"1"];
        [array_hieghtExpansion addObject:@"2"];
        [array_hieghtExpansion addObject:@"3"];
        [array_hieghtExpansion addObject:@"4"];
        [array_hieghtExpansion addObject:@"5"];
        [array_hieghtExpansion addObject:@"6"];

        array_widthExpansion = [[NSMutableArray alloc] init];
        [array_widthExpansion addObject:@"1"];
        [array_widthExpansion addObject:@"2"];
        [array_widthExpansion addObject:@"3"];
        [array_widthExpansion addObject:@"4"];
        [array_widthExpansion addObject:@"5"];
        [array_widthExpansion addObject:@"6"];

        array_alignment = [[NSMutableArray alloc] init];
        [array_alignment addObject:@"Left"];
        [array_alignment addObject:@"Center"];
        [array_alignment addObject:@"Right"];

    }
    return self;
}

and

int heightExpansion = [pickerpopup_heightExpansion getSelectedIndex];
int widthExpansion = [pickerpopup_widthExpansion getSelectedIndex];
