> 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. Interestingly version 1.8.16 does not appear to suffer from this issue.
> I have tried 2 different thermal printers, a GK420d and a CITIZEN CL-S400DT(Z) and both output the same.
> When printing the label directly from the GNOME document viewer (Evince) the label prints clearly on both printers.
> Please find examples of these labels attached.
> Can anything be done to prevent these quality issues?
> Thanks,
> David
