;	This is an example of the source of the data file "prtctl.cfg"
;	which fits for ESC/P dots matrix printer with 24 pins
;
;	Get "prtctl.cfg" as in the following example
;
;	masm prtctl,,,,
;	link prtctl,,,,
;	exe2bin prtctl prtctl.cfg


ESC		equ	01bh	; This will be used in the following

	; This defines a format to send an integer
NO_NUM		equ	0	; no data of a number for the control sequence
BINARY_LTOH	equ	1	; send an integer by binary from low byte
BINARY_HTOL	equ	2	; send an integer by binary from high byte
DECIMAL_3	equ	3	; send an integer by 3 digits decimal figures
DECIMAL_4	equ	4	; send an integer by 4 digits decimal figures
DECIMAL_5	equ	5	; send an integer by 5 digits decimal figures
DECIMAL_V	equ	6	: send an integer by decimal figures

TOTAL_BYTE	equ	0x80	; multiply by VERT_BYTES
ISO_NUMBER	equ	0x40	; indicate the last digit character adding 10h
DIVIDEBY_2	equ	0x10	; devide by 2^j: j=0,1,2,3 -> DIVIDEBY_2*j
MULT_CONST	equ	0x08	; multiplied by constant

	; This defines the arrangement of 8 bits dots data into a byte
TOP_IS_LOW	equ	80h	; This is for PC-PR etc. not for ESC/P
				; The upper position in dots image corresponds
				;  to the lower position of bits in a byte data
TOP_IS_HIGH	equ	0	; This is the converse of the above

LEFT_IS_HIGH	equ	40h	; The first byte is a line
				; The left is higher bit
LEFT_IS_LOW	equ	0c0h	; The first byte is a line
				; The left is lower bit

VER_2_0		equ	'Q'	; Version 2.0

;--------- 1st part to be modified ---
DOT_TYPE	equ	TOP_IS_HIGH
				; Define the arrangement of dots
VERT_BYTES	equ	3	; This is for VERT_BYTES*8 pins printer
				; Should be smaller than 16
H_WMIN		equ	1	; The minimal width of horizontal skip is
				;  H_MIN*8 dots
H_WMAX		equ   (1440/8)	; The maximal width of horizontal skip and
				; the maximal width to send dots image data
				; in one time are H_MAX*8 dots width
