solution native pour imprimer un pdf sur une imprimante en Java
Bonjour,
Je cherche une solution native pour imprimer un pdf sur une imprimante en Java.
J'ai essayé différentes méthodes:

| public static void testPrint(){
DocFlavor flavor = DocFlavor.INPUT_STREAM.PDF;
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
//aset.add(MediaSizeName.ISO_A4);
PrintService[] pservices =
PrintServiceLookup.lookupPrintServices(flavor, aset);
for (int i=0;i<pservices.length;i++){
System.out.println(pservices[i]);
}
if (pservices.length > 0) {
System.out.println("Imprimante selectionnée: " + pservices[0]);
DocPrintJob pj = pservices[0].createPrintJob();
try {
FileInputStream fis = new FileInputStream("C:/BCS_TEST_perso.pdf");
Doc doc = new SimpleDoc(fis, flavor, null);
pj.print(doc, aset);
} catch (FileNotFoundException fe) {
System.out.println(fe);
} catch (PrintException e) {
System.out.println(e);
}
}
} |
mais celle-ci ne donne rien. et si j'utilise DocFlavor.INPUT_STREAM.AUTOSENSE, j'ai des caractères bizarres...
Ensuite avec l'API JPedal, qui ne marche pas...

mais il m'imprime le pdf sans les images:

| Imprimante: Win32 Printer : \\neit\BAT26-IMSIE22-NB
sun.awt.image.ImageFormatException: Unsupported color conversion request |
Une meilleure idée d'implémentation?
Merci :-)
