Since the Brother printer requires certain escape sequences to include a CTRL-I, the escape sequences in the Brother Manual may have to be modified in order to avoid interface cards from "trapping" the CTRL-I in the card. This occurs in the following situations:
 
1.  Apple IIe with Super Serial Card -- add the following IN FRONT OF THE NORMAL SEQUENCE:  <CTRL-I> Z RETURN
 
2.  Apple IIc -- add the following IN FRONT OF THE NORMAL SEQUENCE: <CTRL-I> Z
 
3.  Apple IIe with Apricorn parallel card and parallel Brother printer add the following IN FRONT OF THE NORMAL SEQUENCE: <CTRL-I> <CTRL-A>
 
Also, Brother's 10-pitch command requires a carriage return as part of the sequence, which does not appear to ever get to the printer.  Instead, use the "set to switch command" (<ESC>S) to get back to 10-pitch.
 
BEST DIP SWITCH SETTINGS FOR APRICORN PARALLEL CARD
| Switch | 1 | 2 | 3 | 4 | 
| ON | X | - | - | - | 
| OFF | - | X | X | X | 
These settings force an 80-column mode and turn off the screen while printing, just like the serial card does.
