barcode is good on browser screen but wrong on print preview

[PanNork]

barcode is good on browser screen, but it seems to be bolder on print preview and can't read by barcode scanner.
here is what i did: DNS1DFacade::getBarcodeSVG($code, 'C128', 1, 75)

1. print preview screen
   

2. browser screen
   

The last image is from other source (it looks well in both).

i have the same problem.
end-up with trying to custom css and use @page selector and then adust barcode width manually, and its work's.
