Tres Finocchiaro commented on PDFBOX-4435:

[~tilman] as an aside/stop-gap we'd be happy to honor the *nearest neighbor* flags and send
them to PDFBOX.  The last we tried, we were [unsuccessful|https://github.com/qzind/tray/issues/249#issuecomment-342975647].

> 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
