I have a problem...perhaps one of you readers can help... I have a DEC LA50 printer connected to my Atari 1040 ST and would like to do graphics dumps. But alas, my printer is NOT Epson compatible. It uses a technique called SIXEL for printing graphics. SIXEL is described as follows: The top 6 verticle dots (first column) of the prnthead are fired according to the received character. These characters must be in the range 63 - 126 (base 10, ie chars ?..c ). The pattern is determined by subtracting an offset of 63 (base 10) from the received character... Therefore, sending an "@" (ASCII 64) character yeilds a bit-pattern of 0000 0001 which fires the top pin. Furthermore: The character "$" ( ASCII 36 ) returns the graphic cursor to the beginning of the line. The character "-" ( ASCII 45 ) returns the cursor and advances the paper by 6 pins. Graphics mode is entered by sending the printer ESC P q (27 80 113) and exited by sending ESC \ (27 92)... I read the article in STart about printer drivers but I did not see an easy way to add the required offset to the driver...any help in this matter would be appreciated. Thanks, Michael O.
