Star has a programming manual you can download here: http://www.starmicronics.com/support/Mannualfolder/linemode_cm_en.pdf

The commands referenced in the Line Mode manual need to be converted into bytes and then sent to the printer. The StarIO iOS SDK package you downloaded has a manual called "README_StarIO_POSPrinter_iOS_SDK.pdf". ( http://www.starmicronics.com/absolutefm/absolutefm/afmviewfaq.aspx?faqid=175 ) Did you check out pages 9-15? The StarIO framework is explained here.

Page 13 shows you how to write to the port using a byte array, but make sure you add StarIO.framework and open the communication port first.

From the manual:

//Set a byte array to send to the printer
//command = { A, B, C, D, Feed 3mm, Full Cut}
unsigned char command = {0x41, 0x42, 0x43, 0x44, 0x1B, 0x7A, 0x00, 0x1B, 0x64, 0x02};

Uint bytesWritten = 0;

@Try
{ 
   While(bytesWritten < (sizeof command)) 
   {
    bytesWritten += [port writePort: command : bytesWritten : sizeof command - bytesWritten];
   }
}
@Catch(PortException)
{
   //There was an error writing to the port
}

Also described is how to close ports (make sure you close every opened port) and getting printer status.
