How to print a document with web services

[stlecho]

I would be pleased if someone could provide documentation on how to print a document by using a web service ?

You can user alfresco web service to add, update, delete content but not to print.
You can download content you want to print and then use Java Print Service API or other API for printing.

Would it be possible to get some code examples of this ?

You can print jpeg file from alfresco using this code. Reference to the file is defined by alfresco nodeUuid.

public static void main(String[] args) throws ContentFault, RemoteException {
      Store workspace = new Store(StoreRef.PROTOCOL_WORKSPACE, "SpacesStore");
      Reference referencePath = new Reference(workspace, "1f177f86-f8d3-40a2-922e-598171e3bf1c", null);
      
      WebServiceFactory.setEndpointAddress("http://localhost:8080/alfresco/api");
      AuthenticationUtils.startSession("admin", "admin");
      try {
         Content[] read = WebServiceFactory.getContentService().read(new Predicate(new Reference[] { referencePath }, workspace, null), Constants.PROP_CONTENT);
         Content content = read[0];
         print(ContentUtils.getContentAsInputStream(content));
      } finally {
         AuthenticationUtils.endSession();
      }
   }
   
   private static void print(InputStream in) {
      DocFlavor flavor = DocFlavor.INPUT_STREAM.JPEG;

      PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
      aset.add(MediaSizeName.ISO_A4);
      aset.add(new Copies(1));

      PrintService[] pservices = PrintServiceLookup.lookupPrintServices(flavor, aset);

      if (pservices.length > 0) {
         DocPrintJob printJob = pservices[0].createPrintJob();
         Doc doc = new SimpleDoc(in, flavor, null);
         try {
            printJob.print(doc, aset);
         } catch (PrintException e) { 
            System.err.println(e);
         }
      } else {
         System.err.println("No suitable printers");
      }
