barcode is printed in different widths on different printers

[IDEAL Software Support]

One and the same barcode is printed in different widths on different printers. Is this a bug, how can I avoid it?

See the previous question and answer. This is caused by different printer resolutions and the nature of barcodes (i.e. aspect rations between thick bars and thin bars).
Workaround: set the printer's resolution of the different printers to the same value, e.g. 300 DPI.
