Possible to print more font sizes between 1x and 2x

[TidemannNorli]

Hi, I was wondering if it is possible to print more text sizes between 1x and 2x with the correct aspect ratio.

The font size steps are extremely big.
2x font size (^^^) is about as big as I will ever print. Therefore it would be really nice to be able to print 1.5x

Could I achieve this by setting the default text size to 0.5x?

Then I would have the following result:
(none) = 0.5x
^^^ = 1x
^^^^ = 1.5x
^^^^^ = 2x
^^^^^^ = 2.5x
^^^^^^^ = 3x

Where in the code can I change this? I tried setting "textScale" to 0.5x but with no luck

Optimally I would want the following font sizes:
1x
1.25x
1.5x
1.75x
2x
2.5x
3x

Do you have support for this, or any tips?

Thanks

Hello!

Yes, the character sizes in receiptline are a bit strange compared to modern technology.
However, 50-year-old technology such as double width and double height characters are still in use in receipt printers.

So I will tell you how to modify receiptline.js to your desired specifications.
This will only work for SVG output.

If you want to print this SVG, convert it to PNG and then convert it to a printer command.
See example receipt/en_print_svg.js.

Line 592:

// w = printer.command.measureText(text[j], printer.encoding) * (wh < 2 ? wh + 1 : wh - 1);
w = printer.command.measureText(text[j], printer.encoding) * [ 1, 1.25, 1.5, 1.75, 2, 2.5, 3, 3.5 ][wh];

Line 608:

// height = Math.max(height, wh < 3 ? wh : wh - 1);
height = Math.max(height, [ 1, 1.25, 1.5, 1.75, 2, 2.5, 3, 3.5 ][wh]);

Line 1016-1017:

// const w = wh < 2 ? wh + 1 : wh - 1;
// const h = wh < 3 ? wh : wh - 1;
const w = [ 1, 1.25, 1.5, 1.75, 2, 2.5, 3, 3.5 ][wh];
const h = w;
