I'm using Libreoffice Calc to print stock labels. I've encoded the texts for use with the code128 format, same as in this online tool, and I can print the barcodes using the Libre Barcode 128 font. When I print my normal size labels they scan correctly.
However I'm having trouble with small labels. The smaller labels need to be about 3,2cm wide in order to fit. So I set the font size to 16pt, but then they don't always scan as easily. Most of the time the barcode scanner doesn't pick it up at all, only sometimes it scans correctly, so this is not a workable solution.
I'm guessing it has to do with barcode being too small in height, so not tall enough. So I figured to just print the same barcode stacked on top of each other in order to make the barcode lines longer. But then have to fidget with the font and cell settings, in order to "merge" the stacked barcodes seamlessly. And, at least in the print preview, it is still not seamless because there are horizontal white lines between the cells.
So my quesion is,
is there a better way to make fonts appear taller but not wider?
Or is there another way to print barcodes with taller lines?
Or is there maybe a better barcode128 font to use?
