FORMAT OF LOGO FILES

This information is made available to companies that may need to
convert other graphic formats to the OGO format.

The file sent to the 410 printer should appear as follows, whereas:

h = Hex representation
X = Indeterminate data
'X' = Parenthesis signal ASCII data
db = Single byte hex width

OPENING PARAMETERS:

If creating a graphic image file in four rotations, send:

'^A0^D67'0dh0ah'+'

If creating graphic image #1 file, send:

'^A1^D67'0dh0ah'+'

If creating graphic image #2 file, send:

'^A2^D67'0dh0ah'+'

The following header and data information should always follow the above:
-----------------------------------------------------
db XXh

;Pixels high

db XXh

;Pixels wide

db 00h

;Always 00h

db XXh

;Bytes wide

db 20h

;Always 20h

db 21h

;Always 21h

db 20h

;Always 20h

db XXh

;Pixels high

db XXh

;Pixels wide

db 7688 DUP (?)

;The decoded graphic data, where a bit

set defines a fired dot. 7688 bytes is equal to a maximum 248 x 248 resolution.

-------------------------------------------------------
'-'

;Signifies end of graphic data

The data between the dashed lines should be decoded before being sent to the printer. This
decoding is a simplified version of ASCII hex:

EXAMPLE:

Data byte = 9Bh

Step 1:

Create two bytes with leading zero

09h, 0Bh

Step 2:

OR the resulting bytes with 30h

39h, 3Bh

Step 3:

Put 39h, 3Bh in file to be sent down to printer
