Dear Tilman

I need one urgent help

Planning the following work around.
I am using the code given below. =C2=A0In that
job.print(attr) =C2=A0takes all the 20 sec in low end client machine

If I create a printable Image / JPG using APIs similar to command line PDFT=
oImage in Server ( which is very high end cluster and may finish all in < 1=
 sec ) and send
JPG Byte Stream to client side,=C2=A0
What should be the code or PDFBox API or Java.awt.print =C2=A0code to print=
 JPG file at client side?
I did a quick browse through on PDFBOx APIs or Java.awt.print APIs but coul=
d not find, hence this request to you.

Requirement
---------------=C2=A0
PDF file Input to printable =C2=A0 JPG =C2=A0PDFBox code sample
JPG bytestream to silent printing either PDFBox or Java.awt.print code
=C2=A0
Code snippet for 1 and 2 will resolve our issue.


Code used
--------------=C2=A0

try
{ f =3D new File("Test.pdf" ) ; is =3D new FileInputStream(f) ; pdDocument =
=3D PDDocument.load(is);=09printWithPaper(pdDocument, "SLEEK") ; }
private static void printWithPaper(PDDocument document, String receiptType)
{ PrinterJob job =3D PrinterJob.getPrinterJob(); job.setPageable(new PDFPag=
eable(document, Orientation.AUTO, true, 300) ) ; Book book =3D new Book(); =
book.append(new PDFPrintable(document, Scaling.ACTUAL_SIZE, true, 300), get=
PageFormat("SLEEK") , document.getNumberOfPages()); job.setPageable(book); =
PrintRequestAttributeSet attr =3D new HashPrintRequestAttributeSet(); job.p=
rint(attr); }
private static PageFormat getPageFormat(String receiptType) {
PageFormat pageFormat =3D new PageFormat();
pageFormat.setOrientation(PageFormat.PORTRAIT);
Paper paper=3D pageFormat.getPaper();
if ("SLEEK".equalsIgnoreCase(receiptType))
{ paperWidth =3D 3.14; paperHeight =3D 50; }
else if
{ //........ }

paper.setSize(paperWidth * 72.0, paperHeight * 72.0);
paper.setImageableArea(0, 0, paper.getWidth(), paper.getHeight());
pageFormat.setPaper(paper);
return pageFormat;
}

>             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 ava=
ilable in local system )=20
>            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
> --------------------------=20
> Use Windows System with < 3 GB RAM
> Use Systems with less number of fonts or without specific fonts in PDF fi=
le  to be printed.
> Printing PDF file=20
> 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.=20
> Doubt
> --------=20
> Not browsed the code, but following is the doubt as causing performance i=
ssue.
> 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 fon=
ts are found in new PDF file to be printed, while printing subsequent times=
.=20
> If the fonts in PDF file to be printed is not available in the .pdfbox.ca=
che file stored in local system/local system what is the behaviour?  Will t=
he code download fonts and update cache for subsequent times or is it limit=
ed by fonts available in local system?  Looks like later is the case and pe=
rformance got hit either due to RAM or not constantly updating fonts cache =
or due to un availability of fonts in local system.
