hi this may help you out try it and post if have any query.

-(IBAction)printFromIphone:(id)sender {

    UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController];
    pic.delegate = self;

    UIPrintInfo *printInfo = [UIPrintInfo printInfo];
    printInfo.outputType = UIPrintInfoOutputGeneral;
    printInfo.jobName = self.documentName;
    pic.printInfo = printInfo;

    UISimpleTextPrintFormatter *textFormatter = [[UISimpleTextPrintFormatter alloc]
                                                 initWithText:yourNSStringWithContextOfTextFileHere];
    textFormatter.startPage = 0;
    textFormatter.contentInsets = UIEdgeInsetsMake(72.0, 72.0, 72.0, 72.0); // 1 inch margins
    textFormatter.maximumContentWidth = 6 * 72.0;
    pic.printFormatter = textFormatter;
    [textFormatter release];
    pic.showsPageRange = YES;

    void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) =
    ^(UIPrintInteractionController *printController, BOOL completed, NSError *error) {
        if (!completed && error) {
            NSLog(@"Printing could not complete because of error: %@", error);
        }
    };
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
        [pic presentFromBarButtonItem:sender animated:YES completionHandler:completionHandler];
    } else {
        [pic presentAnimated:YES completionHandler:completionHandler];
    }
}
