Poor print quality of pdf using Atril


I am running CentOS 7.3 with the Mate desktop. PDF files are opened by Atril Document Viewer 1.16.1 (Mate fork of Evince). In general this works just fine. The documents in question, Red Hat documentation documents, open fine and are clear on screen. However, if I attempt to print one of the documents, the print quality is very poor.

Letters are malformed and some appear to be missing pixels. The line thickness in letters is inconsistent. For example in a lower case "m" the left vertical line is about 1 pixel thick and the other two vertical lines are about 3 times that wide. The next occurrence of m has a thin middle line and the other two are OK. About the only consistency I find is that i and l are VERY thin. It looks like the print came from a worn out dot matrix printer (or an old HP Laserjet 1 without the post script option).

The printer is a Brother HL5170DN laser printer with a generic postscript driver. It will print other jobs such as Office documents, web pages, text files from pluma etc. just fine. As a test I opened one of the RHEL manuals in Acrobat Reader on Windoze 7. The print quality was PERFECT

And the questions are....

Can the print quality of evince be improved?

Is there a better PDF viewer which I might use? I understand that Acrobat Reader is no longer supported on Linux.

As to the first question... I see several "Liberation" and "DejaVu" Fonts listed in Atril. If the documents in question contain a font which is not "installed" in Atril and Atril is substituting something close - could that be the issue? How do I determine what fonts are in a pdf and add them to the viewer?

TIA,

Ken

I have tried Okular and Foxit (which I used for years on Windoze). Both look fine on screen. Okular produces the same poor print quality. Foxit prints very nice. As good as Acrobat Reader I would say. The only problem is that it is SLOOOOOOOOW to print. But it does open a PDF in a flash (and it is not as big as Okular).

Still looking for suggestions.

Thanks again,

Ken

Update: My first test with Foxit was pulling a random page out of a LARGE document. I just printed a complete 12 page PDF from the same source and it printed about as fast as with Atril but with EXCELLENT print quality.

I think that is now solved - in that case please mark the thread solved.
Otherwise I think it is a font related issue: the font specified was not installed and that caused some trouble. But it is only a wild guess.

Thanks pan64,

I have a work around but I would not say it is solved. I also suspect something with the fonts or perhaps the printer driver? I am hoping someone will have some input. It not, I will consider the work around a solution.

I don't think anyone can help you without additional information. http://catb.org/~esr/faqs/smart-ques...html#beprecise
