That article claims that there are performance issues, not that it's
unsupported. Are they the same issue (I assume so, 27 minutes to print is
atrocious :))
Is there something that an Oracle subscriber can do to help? Today,
coincidentally, I just received another, separate client report out of memory
issues on another, unrelated PDF and when I test it, I can confirm that
PDFBOX/Java prints it to raster and it uses over 1GB of ram to print. If it's
not an upstream bug, perhaps we can add some compat code to disable
transparency altogether?
If it is upstream, I'm [not afraid to reach out to Oracle for

It's definitely rasterizing. Here's a comparison (PDFBOX 2.0.13, Java 8u192,
Windows 10)
[^comparison.png]
* PDFBOX printed through PDFCreator = rasterized
* Preview in Acrobat = vector
* Acrobat printed through PDFCreator = vector
Command line:
{{*> java -jar pdfbox-app-2.0.13.jar PrintPDF -printerName PDFCreator
label.pdf*}}
{quote}I assume you wrote this from looking at the result PDFs when printing to
PDF.

Correct.

My current thought is this:
- in PageDrawer, setRenderingHints() should get from a map that contains the
rendering hints. This map is passed in PageDrawerParameters. If that map is
null, use the current default.
- in PDFRenderer, initialize the map as it is done today (with special setting
for b/w), and also offer getter / setter.
- in PDFPrintable, offset a new option (getter / setter) "forceBitonal" which
will pass the appropriate map. Alternatively, offer getter/setter for map. (The
"simple" option would be easier to understand, and one could also force the use
of a bitonal image when the dpi option is set. The dpi option (force the use of
an image) has often been used with label printers.
[~tresf] does this sound good for you and your clients?

Yeah, this is all tricky… in the meantime I tried to remove the /Interpolate
flag and print, and it changes nothing - because "isScaledUp" is decided only
related to the CTM, not related to the actual zoom, for whatever reason.
Another thing I tried was to detect whether the target is b/w but I failed that
one too - the printer graphics device presents itself as supporting color.
The best would be to tell PageDrawer that the target is b/w; but this must be
passed through PageDrawerParameters, which must be set in the PDFRenderer,
which must be set in -PDFPageable- PDFPrintable. This sounds complex.

The 3rd party app uses the PDFBOX API directly. Coercing a good black/white
image through a 600dpi command line render won't make it into the 3rd party
product (I'm the developer). We're always willing to add flags (or a code
shim) to fix and/or advanced API settings, but the issue here appears to be
that the PDF is force PDFBOX to a rasterized print which needs to be fixed
either in the PDF or in the render.

[jira] [Comment Edited] (PDFBOX-4435) Poor quality printing of PDF label
[
https://issues.apache.org/jira/browse/PDFBOX-4435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16746372#comment-16746372

Thanks for the reply [~tilman].
Would any of the above affect strokes?
I ask as the entire label prints this way not just the QR code, you can see the
stroked lines and text in the images differ between v1.8 and v2 also.

> 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
