Question
i want to have a coupon on my page in color but i only want it to print b&W
people are complaining it uses too much color ink
thank u  do u know a javascript i can use to make it print only black and white

Answer
Hi Marv,
       Hope you are doing well.

If you are using images for showing coupons, i would suggest you to use the following GD Library code in PHP (if you have done your website using PHP), before printing it.

header("content-type: image/jpeg");
$img = imagecreatefromjpeg('yourimage.jpg');
imagefilter($img, IMG_FILTER_GRAYSCALE); //first, we are converting it to grayscale
imagefilter($img, IMG_FILTER_CONTRAST, -255); //then, we are applying a full contrast
imagejpeg($img);

The above code, converts your image to black and white, before printing.

If i am unclear (or) if i am not giving you the solution for what you have asked, feel free to ping me back, with a brief description about the issue (and possibly your website address, to take a look). I would be glad to assist you further.

Have a great day and all the very best, marv !
