Function 05h (5)         Printer Character Output

Outputs a character to the standard printer device.

On entry:      AH         05h
DL         Character

Returns:       Nothing

                                                                          

This function outputs the character whose ASCII value is in DL to the
standard printer device, which is normally the first parallel port,
LPT1.

Notes:         If the device is busy, the function waits until it
is ready.

If a Ctrl-Break (Ctrl-C) is detected, INT 23h is
executed following output.

Because this functions offers no way to determine
printer status, it is preferable to open the LPT1
device as a file.

For greater control, use the ROM-BIOS services (INT
17h).
