Printer Controls – Data Processing
The printer can be operated in two modes, Online and Buffer mode. In online mode, the characters are printed as they are received. In buffer mode, the characters received are stored in the print buffer and printed upon receipt of the EOT character (^D). Also if the printer is in Buffer Mode and the print buffer is full, the printer will start printing but will remain in the Buffer Mode until the Online Mode command is sent to the printer.
