1488618 - PDF viewer prints fuzzy; save-as-PDF results in garbled PDF.

Status: RESOLVED DUPLICATE of bug 1269023

(Firefox :: PDF Viewer, defect, P3)

Description

[Benoit Jacob [:bjacob] (mostly away)]

Attachment: Garbled PDF produced by save-as-PDF

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:61.0) Gecko/20100101 Firefox/61.0
Build ID: 20180807170231

Steps to reproduce:

In Firefox's built-in PDF viewer, I opened a PDF paper from arXiv, such as
https://arxiv.org/pdf/1610.08364.pdf

I tried printing it on my printer; and I also tried saving-to-PDF.


Actual results:

When printing on my printer, it looked fuzzy. Each letter looked surrounded by a thin stippled pattern, as if it was bordered by 'gray' pixels (which my black-and-white printer renders stippled). It looks a bit as if rasterized at a too low resolution.

When saving-as-PDF, I got the attached, garbled file, firefox.pdf.  It looks the same, equally garbled, no matter in what application I open it: in Firefox's own PDF viewer, in Chrome's, and in Mac's "Preview". Specifically: the fonts are wrong, the glyph positioning is wrong.

Thus, it really seems that what Firefox's PDF viewer does when printing-to-printer and what it does when saving-to-PDF, are two separate things, and they are both wrong but in different ways.


Expected results:

Both print-to-printer and save-as-PDF should look the same and should look sharp and use the right fonts.

I haven't tested printing to paper, but printing to PDF seems to be working well now.
