No issues here; I'm using this package to generate SVG barcodes which will show up in a PDF document (via barryvdh/laravel-snappy):
{!! DNS1D::getBarcodeSVG($foo->bar, "C39", 1, 25, '#2A3239') !!}

@toby I always having the issue during printing, the barcode always show nothing only the border, i need to close it and print again then it only will appear.

I just tested it and inserted {!! DNS1D::getBarcodeSVG('123', "C39", 1, 25, '#2A3239') !!} in a blade file and it showed up correctly the first time. Even printing the page via ctrl+p works. Also echo '<img src="data:image/png;base64,' . DNS1D::getBarcodePNG("4", "C128B") . '" alt="barcode" />'; worked...
Does it make a difference if you change the browser?

@toby Are you using google chrome to test it?

Maybe there is a CSS/JS problem..? What happens if you use a blank blade file (no CSS, no JS) and just display the barcode?

@toby I tried {!! DNS1D::getBarcodeSVG('123', "C39", 1, 25, '#2A3239') !!} , it worked for me, hehe. The last 3 params is width height and color right?

Great :)
Yep, it's width, height and color (see vendor\milon\src\Milon\Barcode\DNS1D)
