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;
}
