Description Leopold 2020-02-29 13:08:09 UTC

Description:
Printing documents with embedded vector graphics results in poor print quality when using the CommonPrintingDialog. A workaround involves using the `File > Export As > Export directly as PDF` functionality.

The use case is printing electronic postage stamps (matrix barcode), which are supplied as PDF documents.

Steps to Reproduce:
1. Create empty Writer document
2. Import a PDF Document with vectors (can be created in inkscape for example)
3a. Print document using the CommonPrintingDialog
3b. export document as PDF using `File > Export as > Export as PDF...

Actual Results:
either PDF document with bitmapped vectors
or printed document with fuzzy vectors

Expected Results:
either PDF document with original quality as embedded PDF
or printed document with crisp edges 


Reproducible: Always

Thank you for reporting the bug.
it seems you're using an old version of LibreOffice.
Could you please try to reproduce it with the latest version of LibreOffice from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the latest version.

Thank you for the quick response! I have now tested this in 6.4.1.2 and can confirm that the problem persists. I have added two attachments showing the result of creating PDFs using the two different workflows.

Isn't this bug 115811? At least for me the inserted PDF is already fuzzy, no need to print anything.

Comment 8 m 2020-06-16 17:36:50 UTC

I think this is a separate one. For me, it showed only after I rotated the pdf-image.

Comment 9 Buovjaga 2020-09-18 17:57:06 UTC

No response in 3 months, so closing as dupe.
