increase spacing between bars?

[AlexTaverna]

the barcodes aren't very readable on my labels, due to the low quality of my label printer. because of this, i'm looking for a way to increase the spacing between bars, or, change the width ratio between bars and spaces. if this is possible, i really wish to know how!

use the "width" property

if the width is too small, the barcode will not be scanned (ex: barcode width: 0.6, printing paper length: 35mm). Do you have any solution? @GiovanniCardamone

@thanglong134 width defines the width of a single bar, I think you should use multiples of 1. (1 means one pixel in canvas).

If you use 0.6 you will use half a pixel, and this means you will have an average value, this isn't correct for the barcode.
