|
We use the -label flag of the image magick convert command to
|
|
generate the text contained in the MESSAGE variable on a white background.
|
|
The image is saved as a png and is named according to the number of
|
|
seconds passed since January 1, 1970. (see: Posix time)
|
|
Then, we calculate a cross product of the image obtained to have the
|
|
length of the ticket in millimeters to print.
|
|
We send this image to the printer via the lp command of the utility
|
|
cups, specifying the dimensions calculated in millimeters.

banderole.sh is supplied WITHOUT a thermal printer. It is necessary
|
|
to have access to such a tool to print a banner. I use a
|
|
Epson TM-T20II which prints up to 80mm wide and connects via USB,
|
|
there are plenty of others, you have to hunt around...
