printf() inside interrupt routine?

As Adam pointed out, and assuming you're using my serial port driver, it's as simple as this:

 // first, find out how much data, if any, is present in 
 // serial port 1's received data queue?
 byte_count = Serial_Port_One_Byte_Count();
 
 // have we received any data?
 if(byte_count > 0)
 {
  // we have fresh data, so read each received byte one at a time
  for(j = 0; j < byte_count; j++)
  {
   // get the next data byte
   data = Read_Serial_Port_One();
 
   // send it out the other serial port
   Write_Serial_Port_Two(data);
 
  // work with camera data here
  }
}
