After an upgrade of acrobat reader 9 to acrobat reader 11 the automatic printing of a pdf. The pdf is opened, but the print does not happen. With acrobat reader 9 it works. But with acrobat reader 11 the printing does not happen.
I discovered when you specify pp.constants.interactionLevel.full it works on acrobat reader 11. But when you specify pp.constants.interactionLevel.silent or pp.constants.interactionLevel.automatic it does not work on acrobat reader 11. But with the full option we have a dialog print box
we do not want.
In our jsp we load a pdf document and create a message handler to detect the print events of a pdf document that is in an <object> tag.
In the pdf document we add
package be.post.lpo.util;
import org.apache.commons.lang.StringEscapeUtils;
import org.apache.commons.lang.StringUtils;
public class AcrobatJavascriptUtil {
public String getPostMessageToHostContainer(String messageName, String messageBody){
return "var aMessage=['"+messageName+ "', '"+ messageBody+"'];this.hostContainer.postMessage(aMessage);";
}
public String getAutoPrintJavaScript(String interactiveType, String printerName,String duplexType) {
String interactiveTypeCommand = "";
if (StringUtils.isNotBlank(interactiveType)){
interactiveTypeCommand = "pp.interactive = " + interactiveType + ";";
}
String duplexTypeCommand = "";
if (StringUtils.isNotBlank(duplexType)){
duplexTypeCommand = "pp.DuplexType = " + duplexType + ";";
}
return "" + // //
"var pp = this.getPrintParams();" + // //
// Nointeraction at all dialog, progress, cancel) //
interactiveTypeCommand + //
// Always print to a printer (not to a file) //
"pp.printerName = \"" + StringEscapeUtils.escapeJavaScript(printerName) + "\";" + //
// Never print to a file. //
"pp.fileName = \"\";" + //
// Print images using 600 DPI. This option MUST be set or some barcodes cannot //
// be scanned anymore. //
"pp.bitmapDPI = 600;" + //
// Do not perform any page scaling //
"pp.pageHandling = pp.constants.handling.none;" + //
// Always print all pages //
"pp.pageSubset = pp.constants.subsets.all;" + //
// Do not autocenter //
"pp.flags |= pp.constants.flagValues.suppressCenter;" + //
// Do not autorotate //
"pp.flags |= pp.constants.flagValues.suppressRotate;" + //
// Disable setPageSize i.e. do not choose paper tray by PDF page size //
"pp.flags &= ~pp.constants.flagValues.setPageSize;" + //
// Emit the document contents. Document comments are not printed //
"pp.printContent = pp.constants.printContents.doc;" + //
// printing duplex mode to simplex, duplex long edge, or duplex short edge feed //
duplexTypeCommand +
// Print pages in the normal order. //
"pp.reversePages = false;" + //
// Do the actual printing //
"this.print(pp);";
}
