We've had troubles with label printers, but not this type of trouble.
Does this also happen if the same document is printed again? If yes, it
is reproducible 1) on PDFDebugger, 2) with a different printer?
Also make sure you're using the latest version of PDFBox (2.0.25), of
java, and of your printer driver.
The code is fine. You can try to use a non zero dpi for PDFPageable
(this option is also available in the menu in PDFDebugger so you can
experiment). But this makes sense only if the problem is reproducible.

I have a small utility that downloads available PDF files from an S3 bucket
and then prints the file to an Afinia L801 label printer.
I use PDDocument.load to load the file. Get a PrinterJob, set a
PrintService on the job, create a PDFPageable on the document, set the
pageable on the job, then call job.print(). Most of the time it works with
no problem, but every now and then we will see a print problem such as the
bottom of an image will be printed, but then the top part of the previous
image will be printed, then a gap, and then the bottom of the current image
again. The next image prints fine. Opening the file in Adobe Reader looks
fine.
I am using pdfbox 2.0.24. The PDF file is about 24m, but I am using 1G
memory for the JVM.
I'm not sure where the problem may be, so any suggestions on how to go
about debugging would be appreciated.
I've included a code snippet and some output logging in case I am doing
something incorrectly.
try (
PDDocument document = PDDocument.load( file )
)
{
StopWatch timer = StopWatch.begin();
logger_.info( "PDDocument loaded" );
for (int i = 0; i < document.getNumberOfPages(); i++)
{
PDPage page = document.getPage( i );
PDRectangle mediaBox = page.getMediaBox();
//

logger_.info( String.format( "Page %s mediaBox: %s, %s x
%s",
i + 1,
mediaBox,
mediaBox.getHeight() / 72,
mediaBox.getWidth() / 72 ) );
}
// Get the PrintService if not already available.
if ( printService == null )
{
printService = choosePrinter();
if ( printService == null )
{
logger_.log( Level.SEVERE, "A printer is required to be
selected!" );
throw new RuntimeException( "A printer is required to
be selected!" );
}
}
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintService( printService );
PDFPageable pageable = new PDFPageable( document );
System.setProperty( "sun.java2d.cmm",
"sun.java2d.cmm.kcms.KcmsServiceProvider" );
// https://pdfbox.apache.org/2.0/migration.html#pdf-printing
job.setPageable( pageable );
logger_.info( String.format( "Print started : %s", file ) );
logger_.info( String.format( "Printer: %s, file: %s",
printService.getName(), file ) );
job.print();
logger_.info( String.format( "Print complete : %s, duration
%s", file, timer ) );
return true;
}
catch ( Throwable e )
{
logger_.log( Level.SEVERE, String.format( "Print failed: %s",
file ), e );
return false;
}
