Huge buffered images can happen in patterns if the pattern matrix and/or
the current transformation matrix result in a huge scale.
You could retry with 2.0.24, but I'm pessimistic. Please share the PDF
(upload to a sharehoster).

Using PDFBox 2.0.20
We use the following to print the PDF:
HashPrintRequestAttributeSet attributes = new
HashPrintRequestAttributeSet();
try(PDDocument doc = PDDocument.load(pdf,
MemoryUsageSetting.setupMixed(5000000L))){
job.setPageable(new PDFPageable(doc));
job.print(attributes);
}
This works really well for thousands of PDFs, but we've run into one
particular PDF that causes an OutOfMemoryException.
The problem PDF is rendered (does not contain bitmaps).
I've provided a huge amount of heap (over 1GB now), and it is still failing.
As near as I can tell from the stack trace (which I'll include below), it
seems like the problem is with creation of a huge buffered image.
The physical page size in the PDF is 8.5 x 11".
The PDFPrintable is configured as follows:
Scaling is ACTUAL_SIZE
dpi is 0.0
subsamplingAllowed is false
renderingHints is null
Here is the stack trace:

Next, I tried setting subsampling to true - this made no difference.
Next, I tried hard coding the dpi to 300f - this works with no problems.
Next, I tried hard coding the dpi to 600f - this does not throw the heap
space error - but with strange results:
- I see "java.lang.OutOfMemoryError" on sys.err - it does NOT throw an
exception
- The pages come off the printer as blank pages
Does anyone have any suggestions on how we can print using the printer's
full resolution?
Thanks!
