Tilman Hausherr commented on PDFBOX-4435: ----------------------------------------- You could try… my feeling is that it is unfixable, because it's the only way to pass the transparency, which is why I haven't attempted to report it myself, although I recently got a more direct access to their bug tracker. Maybe it's different for a paid subscriber. The speed and the rasterization are the same problem IMHO, see also https://blog.idrsolutions.com/2012/05/avoid-transparency-when-printing-in-java/ And I searched again today, and maybe it is a industry-wide problem: https://stackoverflow.com/questions/6286665/what-causes-wpf-printer-output-to-be-rasterized If possible I'd like to see the file you mention. > Poor quality printing of PDF label > ---------------------------------- > > Key: PDFBOX-4435 > URL: https://issues.apache.org/jira/browse/PDFBOX-4435 > Project: PDFBox > Issue Type: Bug > Components: Rendering > Affects Versions: 2.0.3, 2.0.13, 2.0.14 > Environment: Lubuntu 16.04, GK420d printer, CL-S400DT(Z) printer > Reporter: David Hancock > Priority: Major > Fix For: 2.0.14, 3.0.0 PDFBox > > Attachments: before_after.png, comparison.png, label-pdfbox-1-8.jpg, > label-pdfbox-2-0.jpg, label.pdf, label.png > > > Hello, > I'm experiencing poor quality printing of PDF courier labels with PDFBox when > printing from the command line with the following command: > {noformat} > java -jar pdfbox-app-*.jar PrintPDF label.pdf > {noformat} > This makes scanning the QR code on these labels troublesome. > I've tried versions 2.0.3, 2.0.13, 2.0.14 (SNAPSHOT) and all produce the same > quality issue.
