Waiting time Epson T88V - ios

Question

PROBLEM:
How to print (multiple) receipts without any delay?
As far as I know, there are at least 3 options to print with a T88V on OSX or iOS device. Unfortunately, all 3 of those options has a flaw.
OPTION 1:
I've been playing around with the official OSX driver (latest version 1.2a) and have no problems printing with it. However, between every print command, there's 1 sec delay.
- (IBAction)button1:(id)sender
{
[self TMAppPrint];
}
- (OSStatus)TMAppPrint
{
TMTextView *textWindow = [[TMTextView alloc] init];
NSPrintInfo *printInfo = [NSPrintInfo sharedPrintInfo];
OSStatus err = noErr;
err = [TMPrintSupport TMSetJobTicket:printInfo printerName:#"TM-T88V" documentSize:NSMakeSize(204.0, 841.8) resolution:#"180x180dpi" speed:#"1" blank:#"Off" paperCut:#"DocFeedCut" chashDrwr1:#"Off" chashDrwr2:#"Off" buzzerControl:#"Off" buzzerPattern:#"Internal" buzzerRepeat:#"1"];
NSPrintOperation *printOperation = [NSPrintOperation printOperationWithView:textWindow printInfo:printInfo];
[printOperation setCanSpawnSeparateThread:YES];
[printOperation setShowsPrintPanel:NO];
[printOperation runOperation];
return err;
}
OPTION 2:
Using the iOS SDK (latest version 1.3.0) I can also print without problems but it's even worse. After sending the print command, there will be 1 sec delay till it prints.
- (IBAction)button2:(id)sender
{
if (printer != nil)
{
errorStatus = EPOS_OC_SUCCESS;
if (builder != nil)
{
int printStatus = EPOS_OC_SUCCESS;
// create a print document
printStatus = [builder addTextLang: EPOS_OC_LANG_EN];
printStatus = [builder addTextSmooth: EPOS_OC_TRUE];
printStatus = [builder addTextFont: EPOS_OC_FONT_A];
printStatus = [builder addTextSize: 1 Height: 1];
printStatus = [builder addTextStyle: EPOS_OC_FALSE Ul: EPOS_OC_FALSE Em: EPOS_OC_TRUE Color: EPOS_OC_PARAM_UNSPECIFIED];
// specify the print data>
printStatus = [builder addText: #"hello!\n"];
printStatus = [builder addCut: EPOS_OC_CUT_FEED];
// send data>
errorStatus = [printer sendData:builder Timeout:1000 Status: &status];
// end communication with the printer>
errorStatus = [printer closePrinter];
}
}
}
OPTION 3:
The last option is using the ESC/POS commands. I managed to get it to print some basic lines but I still don't understand most of it. There's no delay in printing though.
- (IBAction)button3:(id)sender
{
printer = [[EposPrint alloc] init];
errorStatus = [printer openPrinter:EPOS_OC_DEVTYPE_TCP DeviceName:#"192.168.1.168"];
builder = [[EposBuilder alloc] initWithPrinterModel:#"TM-T88V" Lang:EPOS_OC_MODEL_ANK];
}
I already directly asked Epson about this, but they couldn't give me any answer except it's working as intended... Which means I have to dive into the ESC/POS commands and learn it or are there still other options?
