                           PRINTER

This option of the external MODE command allows you to control a 
standard printer port. You can control up to 3 of them.

   MODE LPT#[:][cpl][,[lpi][,ra]]
   MODE LPT#:] [COL[UMN]S=cpl] [LINES=lpi] [RETRY=ra] [/STA[TUS]] [new DOS 4.0]

LPT# is the printer port that the printer you want to command is on.
    It can be LPT1, LPT2 or LPT3.

cpl is the maximum length of a line, 132 or 80 (by default) characters.

lpi is the vertical spacing, either 6 (by default) or 8 lines per inch.

ra is the retry action to take when a status check detects a busy status.
    The default is not to do anything, and abandon the print operation. The
    Ctrl-Break key will force DOS to stop trying if busy (when the B or P
    option was specified), if you want to abandon the print operation.
    E - Return error 						[new DOS 4.0]
    B - Same as P for DOS 3.31 and before			[new DOS 4.0]
    P - Continue trying to send characters if busy	    [before DOS 3.31]
    R - Return ready anyway					[new DOS 4.0]

/STA or /STATUS will display status information for the port.
