Problem on barcode printing

[Agência Vmc]

Hi, im having a problem when i try to print barcodes using google chrome.

In the browser i see the correct rendering of the barcode, but in the print preview and in the printed sheet the barcode are wrong.

This is the correct barcode, i see this in the browser:

This is the same barcode in the print preview:

This is a piece of the code for render the barcode:

<img src=http://localhost/SIGA-2015/CG_SIGA-plus/static/boletophp/imagens/p.png width=1 height=50 border=0>

<img src=http://localhost/SIGA-2015/CG_SIGA-plus/static/boletophp/imagens/b.png width=1 height=50 border=0>

<img src=http://localhost/SIGA-2015/CG_SIGA-plus/static/boletophp/imagens/p.png width=1 height=50 border=0>

<img src=http://localhost/SIGA-2015/CG_SIGA-plus/static/boletophp/imagens/b.png width=1 height=50 border=0>

<img src=http://localhost/SIGA-2015/CG_SIGA-plus/static/boletophp/imagens/p.png width=1 height=50 border=0>

<img src=http://localhost/SIGA-2015/CG_SIGA-plus/static/boletophp/imagens/b.png width=1 height=50 border=0>

<img src=http://localhost/SIGA-2015/CG_SIGA-plus/static/boletophp/imagens/p.png width=1 height=50 border=0>

<img src=http://localhost/SIGA-2015/CG_SIGA-plus/static/boletophp/imagens/b.png width=1 height=50 border=0>

<img src=http://localhost/SIGA-2015/CG_SIGA-plus/static/boletophp/imagens/p.png width=3 height=50 border=0>

<img src=http://localhost/SIGA-2015/CG_SIGA-plus/static/boletophp/imagens/b.png width=3 height=50 border=0>

How i say, in the browser the barcode is perfect, but in the print preview are wrong. Like if the print preview are changing my <img> proprietes or adding some css?

I test this in mozilla firefox, and the print are ok, like in the browser. The problem happends just with google chrome.

Any idea for solve this problem? Thanks!

Does the actual printed page show the same issue?

It looks a bit unusual for the barcode images to have width 1 or 3. Is it the first image shown actual p.png or b.png? I tried with

 the first png image with proper width, both print preview and printed page show correct results. Does changing the width help?

If the problem persists, can you pls file a bug at https://bugs.chromium.org/p/chromium/issues/entry with the image and webpage

attached, so that we can follow along?

I think p.png is white (padding) and b.png is black. The barcode is constructed using many little images of black and padding.
