Q1: there is no such thing as multipage PNG. TIFF has multipage, but the
compression for non-black+white images is not very good. So you'll have to
either make several requests to the server, or pack the files into a single
one. Doing two requests brings an advantage: you could ask for page 1 and page
2 at the same time, i.e. render both pages similarly. (But the server must use
different PDDocument objects). (I assume the computer prints two receipts, one
for that the customer signs and one that he/she keeps)
Q2: re size: that is tricky... you either find a resolution that brings an
image is exactly the size that will be printed, or you render to a higher
resolution and use a drawImage() method that does scaling, e.g. {{boolean
drawImage(Image img, int x, int y, int width, int height, ImageObserver
observer)}}. I don't know the dpi of your printer, nor the exact size of the
paper.
Q3: sorry, don't know.
Btw code can be included within "{{code}}...{{code}}", this looks nicer in JIRA.

Thanks a lot for the code Snippet. I could create PNG file from PDF with
little modifications ( capturing in to BufferedImage bim )
But few requirements.
Q1: ImageIOUtil.writeImage() seems to create PNG from PDF file, page by Page,
how do we convert multipage PDF to multipage PNG?
Q2: The out put PNG looks shrinked and very smaller in size. How to preserve
the size or can it be scaled to actual size at client side using java.awt.print?
Q3: Any idea of how much of processing is done for converting PDF to PNG using
PDFBox and how much is left to print with PNG as input using java.awt.print?
This will give an idea of gain in performance by doing PNG conversion at server
side and PNG to print at client side
Thanks
FYI
Printing PDF with PDF took 14 to 20 sec, but this is not good measure as this
is to Ms XPS
Creating PNG with PDF as input took 6 to 7 sec
Don't know how much processing is left to print PDF from PNG using
Java.awt.print()

Q1: you'll know it when you test it. Time is spent by creating image,
transferring it, and printing it. Maybe try printing only to see how long it
takes.
Q2: example for 300dpi:
{code}
PDDocument document = PDDocument.load(new File(pdfFilename));
PDFRenderer pdfRenderer = new PDFRenderer(document);
int pageCounter = 0;
for (PDPage page : document.getPages())
{
pdfRenderer.renderImageWithDPI(pageCounter, 300, ImageType.RGB);
// suffix in filename will be used as the file format
ImageIOUtil.writeImage(bim, pdfFilename + "-" + (pageCounter++) + ".png",
300);
}
document.close();
{code}
There's also a writeImage method with an OutputStream.
Q3: only awt
If the image is pure black and white, then I recommend TIF, this makes even
smaller files than PNG. You'll need jai_imageio.jar. But start with PNG first.

Dear Tilman
I need one urgent help
Planning the following work around.
I am using the code given below. In that
job.print(attr) takes all the 20 sec in low end client machine
If I create a printable Image / JPG using APIs similar to command line
PDFToImage in Server ( which is very high end cluster and may finish all in < 1
sec ) and send
JPG Byte Stream to client side,
What should be the code or PDFBox API or Java.awt.print code to print JPG file
at client side?
I did a quick browse through on PDFBOx APIs or Java.awt.print APIs but could
not find, hence this request to you.
Requirement
---
PDF file Input to printable JPG PDFBox code sample
JPG bytestream to silent printing either PDFBox or Java.awt.print code
Code snippet for 1 and 2 will resolve our issue.

PDFBox tries to use "the right font", and if it can't find it, it will use a fallback font. The number of fonts may play a role that it gets *slower* with *more* fonts but only the first time. I'm really interested in the W7 performance indices. If the machine is the future production machine, it makes sense for the manufacturer to make it cheap. E.g. the W7 starter edition / 32 bit windows, cheap RAM, simple mainboard, etc. As long as display and printing works properly, it doesn't matter. > PDFBox 2.0.0-RC2 and earlier 2.0.0 SNAPSHOT Versions print performance is > poor with systems having low RAM < 3GB and lower number of fonts. > --- > > Key: PDFBOX-3133 > URL: https://issues.apache.org/jira/browse/PDFBOX-3133 > Project: PDFBox > Issue Type: Improvement > Components: PDModel >Affects Versions: 2.0.0 > Environment: MS Windows Systems with low RAM < 3GB and number of > fonts were less < 592 (or if desired fonts in PDF to be printed are not > available in local system ) >Reporter: Sridhar >Assignee: John Hewson > Labels: performance > Fix For: 2.0.0 > > > PDFBox 2.0.0-RC1, SNAPSHOTS and RC2 versions print takes 15+ seconds. > Steps to reproduce > -- > Use Windows System with < 3 GB RAM > Use Systems with less number of fonts or without specific fonts in PDF file > to be printed. > Printing PDF file > Took 14 to 20 seconds in system with 3 GB RAM which had 522 foints > Took 24 to 34 seconds in system with 2 GB RAM which had 90 fonts > Took only 2.5 seconds in system with 8 GB RAM which had 1025 fonts. > Doubt > > Not browsed the code, but following is the doubt as causing performance issue. > Though the code caches fonts by storing fonts in local .pdfbox.cache file > first time and caching fonts for subsequent times. > Not clear whether the code updates the pdfbox fonts cache file if new fonts > are found in new PDF file to be printed, while printing subsequent times. > If the fonts in PDF file to be printed is not available in the .pdfbox.cache > file stored in local system/local system what is the behaviour?

{quote}
[~Sridhar] Although I doubt it's the RAM (my bet is on the printer firmware or
the cable or the driver), there's one way to find out: take the 8GB from the
fast computer and put it into the slow computer and see what happens (make sure
that the memory is accepted by the computer).
Desperate situations require desperate measures.

This is the fault of Java's Printing API and there's not much we can do about it. Likewise for printing to physical printers: Java's print drivers are really slow with the output from PDFBox, for no good reason (it's because we render our own fonts, but that's no excuse for the level of slowness encountered). You should run PDFToImage and see how long it takes to generate a PNG file, that way we eliminate print drivers from the equation. The speed of PDFToImage represents the speed of PDFBox, if you get slower printing performance then it's due to Java. > PDFBox 2.0.0-RC2 and earlier 2.0.0 SNAPSHOT Versions print performance is > poor with systems having low RAM < 3GB and lower number of fonts. > --- > > Key: PDFBOX-3133 > URL: https://issues.apache.org/jira/browse/PDFBOX-3133 > Project: PDFBox > Issue Type: Improvement > Components: PDModel >Affects Versions: 2.0.0 > Environment: MS Windows Systems with low RAM < 3GB and number of > fonts were less < 592 (or if desired fonts in PDF to be printed are not > available in local system ) >Reporter: Sridhar >Assignee: John Hewson > Labels: performance > Fix For: 2.0.0 > > > PDFBox 2.0.0-RC1, SNAPSHOTS and RC2 versions print takes 15+ seconds. > Steps to reproduce > -- > Use Windows System with < 3 GB RAM > Use Systems with less number of fonts or without specific fonts in PDF file > to be printed. > Printing PDF file > Took 14 to 20 seconds in system with 3 GB RAM which had 522 foints > Took 24 to 34 seconds in system with 2 GB RAM which had 90 fonts > Took only 2.5 seconds in system with 8 GB RAM which had 1025 fonts. > Doubt > > Not browsed the code, but following is the doubt as causing performance issue. > Though the code caches fonts by storing fonts in local .pdfbox.cache file > first time and caching fonts for subsequent times. > Not clear whether the code updates the pdfbox fonts cache file if new fonts > are found in new PDF file to be printed, while printing subsequent times. > If the fonts in PDF file to be printed is not available in the .pdfbox.cache > file stored in local system/local system what is the behaviour?

I don't know much about applets, ie. how to configure their JVM parameters; with the command line, you can set the amount of memory, e.g. -Xmx1g. So it would be worth to test whether it works fast on a "slow" computer if you set the memory to a good number (and close everything else). See also the task manager (taskmgr.exe) whether there are some applications that use your memory and/or your CPU. Another thing to test (I may have mentioned this before) is what happens if you switch printers and/or printer cables. > PDFBox 2.0.0-RC2 and earlier 2.0.0 SNAPSHOT Versions print performance is > poor with systems having low RAM < 3GB and lower number of fonts. > --- > > Key: PDFBOX-3133 > URL: https://issues.apache.org/jira/browse/PDFBOX-3133 > Project: PDFBox > Issue Type: Improvement > Components: PDModel >Affects Versions: 2.0.0 > Environment: MS Windows Systems with low RAM < 3GB and number of > fonts were less < 592 (or if desired fonts in PDF to be printed are not > available in local system ) >Reporter: Sridhar >Assignee: John Hewson > Labels: performance > Fix For: 2.0.0 > > > PDFBox 2.0.0-RC1, SNAPSHOTS and RC2 versions print takes 15+ seconds. > Steps to reproduce > -- > Use Windows System with < 3 GB RAM > Use Systems with less number of fonts or without specific fonts in PDF file > to be printed. > Printing PDF file > Took 14 to 20 seconds in system with 3 GB RAM which had 522 foints > Took 24 to 34 seconds in system with 2 GB RAM which had 90 fonts > Took only 2.5 seconds in system with 8 GB RAM which had 1025 fonts. > Doubt > > Not browsed the code, but following is the doubt as causing performance issue. > Though the code caches fonts by storing fonts in local .pdfbox.cache file > first time and caching fonts for subsequent times. > Not clear whether the code updates the pdfbox fonts cache file if new fonts > are found in new PDF file to be printed, while printing subsequent times. > If the fonts in PDF file to be printed is not available in the .pdfbox.cache > file stored in local system/local system what is the behaviour?

A typo in previous comment
with 0 dpi it is slow 30 to 60 sec wide variations, but with 300 dpi it is
better 14 to 20 sec. but 14 to 20 sec also is slow.
Code snippet
---
job.setPageable(new PDFPageable(document, Orientation.AUTO, true, 300) ) ;
Book book = new Book();
book.append(new PDFPrintable(document, Scaling.ACTUAL_SIZE, true, 300),
getPageFormat("SLEEK") , document.getNumberOfPages());
With 300 DPI, it took 14 to 20 sec, but with 0 DPI, the printout took 30 to 60
sec. So your suggestion in PDFBOX-3046 to use 4 argument ctors showed
performance improvements, but still, even with 4 argument 300 dpi ctors, the
printout is slow.

Thanks John
Slow performance observed and indicated in bug report is with 300 dpi in both
PDFPageable() and PDFPrintable() constructors.
Even with 300 dpi, which would have forced to use rasterization algorithm, the
printout is slow 14 to 20 secs in 3 GB system ( redirection to MS XPS file)
and also actual pritout in thermal printer with 2 GB system took 24 to 34 secs.
Another note: compared to 0 dpi in PDFPageable() and PDFPrintable() ctors, it
took more time, indicating that it would not have used rasterization.
With 600 dpi got outofMemory Exception in 3 GB machine.
Code snippet below
public void run() {
PDDocument pdDocument=new PDDocument();
FileInputStream is = null ;
File f = null ;
try {
f = new File("Test.pdf" ) ;
is = new FileInputStream(f) ;
pdDocument = PDDocument.load(is);
printWithPaper(pdDocument, "SLEEK") ;
}
private static void printWithPaper(PDDocument document, String receiptType)
{
PrinterJob job = PrinterJob.getPrinterJob();
job.setPageable(new PDFPageable(document, Orientation.AUTO, true, 300)
) ;
Book book = new Book();
book.append(new PDFPrintable(document, Scaling.ACTUAL_SIZE, true, 300),
getPageFormat("SLEEK") , document.getNumberOfPages());
job.setPageable(book);
PrintRequestAttributeSet attr = new HashPrintRequestAttributeSet();
job.print(attr);
}
private static PageFormat getPageFormat(String receiptType) {
PageFormat pageFormat = new PageFormat();
pageFormat.setOrientation(PageFormat.PORTRAIT);
Paper paper= pageFormat.getPaper();
if ("SLEEK".equalsIgnoreCase(receiptType)) {
paperWidth = 3.14;
paperHeight = 50;
}
else if {
//
}
paper.setSize(paperWidth * 72.0, paperHeight * 72.0);
paper.setImageableArea(0, 0, paper.getWidth(), paper.getHeight());
pageFormat.setPaper(paper);
return pageFormat;
}

The cache is only for system fonts, if they haven't changed the cache won't be rebuilt. Given that you're seeing faster times with _more_ fonts, it's pretty clear that the cache is not the issue here. What you're descibing is faster print times when you have more RAM available. That's not supprising. Java2D's print performance is pretty poor, we have a workaround you can use to address that as seen in PDFBOX-3046, I suspect this issue is a duplicate of that one. Try out the solution posted there and let me know if it works for you. > PDFBox 2.0.0-RC2 and earlier 2.0.0 SNAPSHOT Versions print performance is > poor with systems having low RAM < 3GB and lower number of fonts. > --- > > Key: PDFBOX-3133 > URL: https://issues.apache.org/jira/browse/PDFBOX-3133 > Project: PDFBox > Issue Type: Improvement > Components: PDModel >Affects Versions: 2.0.0 > Environment: MS Windows Systems with low RAM < 3GB and number of > fonts were less < 592 (or if desired fonts in PDF to be printed are not > available in local system ) >Reporter: Sridhar > Labels: performance > Fix For: 2.0.0 > > > PDFBox 2.0.0-RC1, SNAPSHOTS and RC2 versions print takes 15+ seconds. > Steps to reproduce > -- > Use Windows System with < 3 GB RAM > Use Systems with less number of fonts or without specific fonts in PDF file > to be printed. > Printing PDF file > Took 14 to 20 seconds in system with 3 GB RAM which had 522 foints > Took 24 to 34 seconds in system with 2 GB RAM which had 90 fonts > Took only 2.5 seconds in system with 8 GB RAM which had 1025 fonts. > Doubt > > Not browsed the code, but following is the doubt as causing performance issue. > Though the code caches fonts by storing fonts in local .pdfbox.cache file > first time and caching fonts for subsequent times. > Not clear whether the code updates the pdfbox fonts cache file if new fonts > are found in new PDF file to be printed, while printing subsequent times. > If the fonts in PDF file to be printed is not available in the .pdfbox.cache > file stored in local system/local system what is the behaviour?
