I downloaded your document and found some single-pixel-wide artefacts in the black areas when rendered.  However they only appear when I dither the rendered colour original BMP to monochrome (not with QPDF) and only with some dithering algorithms, so I do not know if they correspond to what you see.

I would suggest that you try rendering with the PDFium option.  See the documentation for SelectRenderer in the reference manual, and reference the DLL where it is installed in the Rendering and Printing Add On folder under the QPDF installation. 

Also if you render to BMP and examine that, instead of printing, you may discover that the problem arises in your printer driver, not in the QPDF library, despite the fact that it does not occur when printing from another application.

Hi Honza,

with version 12.11 and PrintDocument i've made the same experiences.
1-2 weeks further i'm able to test with 13.12 - perhaps that version has always a correction regarding this issue.
It'll be an issue from creation.
The more than 100-mb-installation of an adobe product can repair these issues on the fly but the slim line installation of QuickPDF not.
Perhpas you should upload this file with a issue-description on the support page...

Hello Ingo,

have you tried the pdf I sent you? The dropbox link should be functional. Alternatively, I can send the pdf to an email. We need to print this pdfs without lines. Unfortunately, such pdfs account for 15% of print data.

Many thanks
Honza

Hi Honza,

i'm not able to download and check the pdf :(
My browser told me after clicking on "download" that the website isn't available.

Cheers and welcome here,
Ingo

Hi,

I have a problem with some pdf documents. When I try to print it from adobe acrobat or any other pdf tool thenit looks OK. When I print it using debenu library I see 1 pixel lines over the document.
Does anyone have an idea where the problem could be? The original pdf and the printed output are attached lower. The link should be valid for 7 days.

Thanks!
