Flex Printing

I am sending a datagrid to print as file (.pdf) from Flex3
AIR app. on Mac OSX.
If the document exceeds 5 pages, the print call fails ... as
if out of memory. I
don't have this problem under 5 pages. Has anyone had or
heard of this issue?

I am trying to do something similar and had the exact same
problem. I am trying to have a company logo dynamically added to a
print job. All attempts at changing the source field on the image
tag before printing failed. I tried creating an image object and
adding to my print view before printing also failed. The image was
generated and displayed on the screen after the print job left the
computer. After trying a few ideas, I came up with this one that
works but is ugly.
The print job will take a completed object on the screen and
add to the print view and then print correctly. So the solution was
to create a "hidden" image of the logo when opening the report
generator. I placed an image tag ahead of the data grid with both
overlappnig on the screen. This makes the image hidden since the
data grid comes later in the code. You then start the print job and
add the hidden complete image to the print view. this prints
correctly. Unfortunately, I found that the addObject function eats
the mxml generated image so no second print attempt! To fix that,
it turns out that if you generate dyanamically a second copy of the
image tag upon opening the report generator, the addObject eats the
static version and leaves the dynamically version alone. You can
then print with the logo image with no problems repeatedly.
As mentioned, this seems very ugly but I have now printed
hundreds of different combinations and it seems to keep working.
If anyone knows of a better solution, I would be very
interested.

Flex Print Job not working with custom component

Hi All,
I have to print pages with header, body and footer. So the thought process was to create a custom component fro header, footer and body. Header component is based on Box, Body is a renderer (which will have fix value of items - and will decide the number of possible pages) and footer is again based on Box.
But when i created a simple Custom component like this for header
<?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:fx=http://ns.adobe.com/mxml/2009
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Declarations>

</fx:Declarations>
<mx:HBox>      <mx:Label id="testLabel" text="Test Container"/>
</mx:HBox>
</mx:VBox>
Then when i try to add this to FlexPrintJob, and save it as 'xps' to see the print output, i get error message that this file is in use or damaged.
    var myPrintJob:FlexPrintJob = new FlexPrintJob();
if(!myPrintJob.start()){
      return;
var header:Header = new Header();
header.width = myPrintJob.pageWidth;
header.visible = false;
FlexGlobals.topLevelApplication.addChild(panierPrintHeader);
myPrintJob.addObject(header);
myPrintJob.send();
FlexGlobals.topLevelApplication.removeChild(panierPrintHeader);
But this does not work and i get the above mentioned exception. Now when i not use the custom component and just have a label or HBox or anything on stage before the print functionality is invoked, it works fine. And this too haapens only if you have a mxml component, i tried by creating a new Label component using actionscript and then provide the same to the printJob, which did not work either. I need help on this, else i will have to take print functionality to server side(Java) which has some business implications, the reason why i am spending time on flex for printing.
Thanks and Regards,
Jigar
Looks like custom component print is not working fine with flex or i am doing something terribly wrong.
Looking forward for help.

Is there nobody in flex community who can help on this....
Looks like a toothless class that adobe actionscript team has provided, which is not liked across much

Flex, Printing / Create PDF without Server?!?

Hi,
after some days of searching a printing solution for flex without using a server or using a second languag (Java), I found the following solutions:
www.alivepdf.org
and
www.bentbit.com
Is there something else out there?!?!?
I can not understand why Adobe, the "mother" of PDF, does not have a nice solution for it?!?!?!
Cheers!

It would probably be a good idea to explain why the solutions you've found are unsuitable.

Flex printing broken by Flash 10.1.53.64 upgrade

We have a large base of flex applications whose printing is now broken on any machine which upgrades to the 10.1.53.64 Flash upgrade. The pages print with white vertical and horizontal bars running through them. Have definitely verified that this is related to the Flash upgrade. Is anyone else experiencing this problem?

For anyone interested, we discovered that the problem Flash 10.1.53.64 introduced was related to a mask used on the print page. By removing the mask and using a different technique we were able to work around the problem. Definitely a potential problem for anyone using a mask on a print page though.

Flex Printing Issue

Dear All,
I have used the following code to print from flex Datagrid in
Flex 1.5.
public function doPrint():Void {
var pj : PrintJob = new PrintJob();
//Save the current vertical scroll position of the DataGrid
control.
var prev_vPosition:Number = dgReportFinal.vPosition;
if(pj.start() != true) {
delete pj;
return;
//Calculate the number of visible rows.
var rowsPerPage:Number = Math.floor((dgReportFinal.height -
dgReportFinal.rowHeight)/dgReportFinal.rowHeight);
//Calculate the number of pages required to print all rows.
var pages:Number =
Math.ceil(dgReportFinal.dataProvider.length / rowsPerPage);
//Scroll down each page of rows, then call addPage() once
for each page.
for (var i=0;i<pages;i++) {
dgReportFinal.vPosition = i*rowsPerPage;
pj.addPage(dgReportFinal);
pj.send();
delete pj;
// Restore vertical scroll position.
dgReportFinal.vPosition = prev_vPosition;
My Issues are:
1. I want content of the DataGrid to be printed, but the
printing prints the content of the datagrid along with the
scrollbars.
This is the same, when I use landscape mode also.
2. When the content of the Datagrid exceeds the width of the
Datagrid (i.e., when we have a hscroll), those contents are not
printed. I think only the content which we view currently is being
printed.
To print headers and footers which are the best controls to
use. Bcoz my headers would look like:
Date: Organization:
Place: Branch:
Report Title
Thanks in advance.
thanks and regards,
Loganathan.P.C.

The feature of printing data which is not visible in the
control is not available in Flex 1.5 but is available in Flex 2
(Beta). Work around can be fragmenting the data as pages for
printing but involves splitting data in grid into a fixed number of
rows for each page.
I can also suggest a work around for you header and footer
issue. you can create a sepearate Print Preview Page which can be
invisible / visible as you wish and on click of print use the
controls in that page and print
tipically the Preview page can be like
mx:Label ---> Header text
mx
ataGrid -- > data which is paged -
mx:Label --- > footer

Flex print problem

Hi guys,
i want to print one canvas(3/4 page) and then followed by some text, images, lists(dynamic), i googled the stuff mostly it says printdatagrid, what if
we have different things like images, lists, formatted text, flex will automatically set the pages or we have specify the pages, since i have some lists in it i cant
tell the height, so how to solve this problem.
thanks for going through.

it seems like we have to provide the dataprovider when the print start() is called.

Send MXML to Java printing Gateway

Hi everybody, i´m developing a printgateway in java to overcome the limitations of the Flex print API. Here´s what i´m doing.
I create a report in Flex and want to send it to the java gateway via sockets.
What a wanted to know is hot to send the report object to my java gateway and print this from there (where i can print directly to the desired printer - without print dialogs to the user.).

i've since tried this code, but am essentially receiving the same result.
   FileInputStream psStream = null;
        try {
            psStream = new FileInputStream("c://testPDF.pdf");
        } catch (FileNotFoundException ffne) {
            ffne.printStackTrace();}
        if (psStream == null) {
            return;}
        DocFlavor psInFormat = DocFlavor.INPUT_STREAM.AUTOSENSE;
        Doc myDoc = new SimpleDoc(psStream, psInFormat, null);
        PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
        PrintService[] services = PrintServiceLookup.lookupPrintServices(psInFormat, aset);
        // this step is necessary because I have several printers configured
        PrintService myPrinter = null;
        for (int i = 0; i < services.length; i++){
            String svcName = services.toString();
System.out.println("service found: "+svcName);
if (svcName.contains("Dell 3100cn PS")){
myPrinter = services[i];
System.out.println("my printer found: " + i + " svc = " +svcName);
break;
if (myPrinter != null) {
DocPrintJob job = myPrinter.createPrintJob();
try {
job.print(myDoc, aset);
System.out.println("printed");
} catch (Exception pe) {pe.printStackTrace();}
} else {            System.out.println("no printer services found");

Perl cgi upload stopped working with Flash 10

First let me just say that PHP is not an option in my environment. Its just not allowed to be used.
I have some really basic Perl upload scripts that work find with flash 9 and below. However since flash 10 these no longer work. I tried using FileRefernce and while I can get all my values as defined by the
$QUERY_VALS_GV->param statement in Perl, I can not get the file handle $QUERY_VALS_GV->upload("fileName"); Any Ideas ?　
Snippet
use CGI;
use CGI qw(:standard);
use CGI::Carp qw/fatalsToBrowser/;
# Values from Flex #
print header();
our $QUERY_VALS_GV = new CGI
our $UPLOAD_FILE_NM_GV = "";
our $DOC_TYPE_IP = $QUERY_VALS_GV->param("docType");
our $USER_NAME_IP = $QUERY_VALS_GV->param("userName");
our $WR_ID_IP = $QUERY_VALS_GV->param("wrId");
our $WR_TYPE_CD_IP = $QUERY_VALS_GV->param("wrTypeCd");
our $FILE_NM_IP = $QUERY_VALS_GV->param("fileName");
our $ACTION_IP = $QUERY_VALS_GV->param("fileAction");our $UPLOAD_FHDL_IP = $QUERY_VALS_GV->upload("fileName");

The resolution was easy. Use the default value for Filedata passed from filereference
our $UPLOAD_FHDL_IP = $QUERY_VALS_GV->upload("Filedata");

Incorrect output in PrintDataGrids

Hello Flex Community,
I have an exciting problem and hope anybody can help me. My
application does the following:
1. I have a panel with two DataGrids one below the other,
which are filled with more than 100 rows.
2. I want to print these DataGrids. I tried to do this - as
decribed in the LiveDocs - with PrintDataGRids.
3. I want that the first DataGrid is printed completely on
multiple pages and finally the second DataGrid.
My problem is that each printed page visualizes both
PrintDataGrids with 10 items in each case. And that is done for the
next 10 pages.
Question: How can I enforce that Flex prints at first the one
DataGrid completely on multiple pages and then the second one???
Gruß Greenhorn

This is a major feature of Flex - inability to print.
You've bumped into the problem that assigning 100% height to
the PDG gets you into the described case.
FlashPLayer uses 2 passes to layout the elements. So, at the
first pass you've got 2 PDGs with 100% height and this thing drives
FP nuts.
As a solution you have to manually calculate available height
and set PDG.height to that value, one PDG at a time.
In my project I am using N-pass technique to layout all
elements correctly, but still I can't overcome all the problems
with mighty "Flex Printing Engine"
PS I am inclined to think that server-side printing solution
is the way to go.(like PDFLib)
Cheers,
Dmitri.

My Ipod was white but now it's black

So, a week ago I dropped my Ipod and the screen turned white.I tried reseting it and restoring it but it still is white. I opened it up to check if anything was out of place and closed it.Now the screen is black. Can you guys help me?

A white screen means the video electronics cannot "talk" to the LCD display panel. A black screen means the back light (a really small and fragile flourescent light) is not working, or the iPod is not powering up.
What could have happened when you opened the iPod is you disconnected the touch screen or you may have damaged the flex print cable that connects the touch screen to the main board. This will keep the iPod from powering up.
The bottom line is, you're hosed, but you do have some options: You can buy a new iPod, or you can invest in a new LCD panel and mabye a touch screen and then see if you can fix what you broke... parts are available on line. eBay and Google are your friends....

Adobe... PrintDataGrid needs previousPage()

It's difficult to provide the ability to go back a page when
showing the user a print preview. It's assumed functionality in
every print preview interface.
Come on Adobe, we need better printing support for Flash/Flex
in general. The OS should be able to handle stuff like which pages
to print, and print orientation too. Very generic, basic
functionality. Why are we still doing this in Flex? The Silverlight
punks are gonna catch up at this rate. :P

Also: since technically when we print multiple pages by
queuing them up in separate print jobs (as the Flex printing
example in the docs), doesn't that mean if other people print stuff
while your Flex print jobs are running, it'll end up in between
your pages?
That really sucks. Better print support is needed if Adobe
wants businesses to use Flex extensively. ^_^ And I don't even want
to think about the performance hit (if any) you take printing lots
of pages like that...

Printing a graphic with a gradient mask in Flex 3-problem

Hello, I am fairly new to flex development. I am puting together a little program that allows the user to upload a picture add a vignette mask in order to achieve a soft edge, and have a problem I cannot find an answer anywhere, maybe someone could help me please.
I want to print a the user photo with a gradient mask or vignette from flex. I managed to show the image correctly on screeen with the gradient mask using this class but the output to paper is a rectangle without the soft mask.
//package to add the mask for display
package com.dm.graphics
   import flash.display.Graphics;
   import mx.containers.Canvas;
   import flash.display.GradientType;
   public class FrameBorderSoft extends Canvas
      override protected function updateDisplayList(w:Number, h:Number):void
         super.updateDisplayList(w,h);
         var g:Graphics = this.graphics;
         g.clear();
         g.beginGradientFill(GradientType.RADIAL, [0x000000, 0x000000, 0x000000, 0x000000],
         [1,1,0.8,0],
         [1,128,195,255],
         horizontalGradientMatrix(0,0,w,h) );
         g.drawRect(0,0,w,h);
         g.endFill();
It works beautifully until I try to print the graphic. The image prints but without the gradient edges (soft) instead it is just a sharp edge rectangle.
Does anyone know how to do this?
Here is my print function:
private function doPrint():void {
                // Create an instance of the FlexPrintJob class.
                var myPrintJob:FlexPrintJob = new FlexPrintJob();
                // Start the print job.
                if (myPrintJob.start() != true) return;
                // Add the object to print. Do not scale it.
                if (tabnavigator1.selectedChild == img1) {
           //switchcolor is a variable to detect if the user changed the background to white or clear.
                         switchcolor = 100;
                      //printCF is the card front container with the photo masked
                   myPrintJob.addObject(printCF, FlexPrintJobScaleType.NONE);
                   myPrintJob.printAsBitmap = false;
                } else if (tabnavigator1.selectedChild == img1b) {
                   switchcolor = 100;
                   myPrintJob.addObject(printCB, FlexPrintJobScaleType.NONE);
I hope this helps to visualize,
I would greatly appreciate any assistance or advise.

Hello, back on my issue, i tested a little bit more the message dispaching.
I read the lazyLoadPolicy class and noticed that it always has to have a ModuleId property in the message to work, that's why the broadcast message didn't work to awake the module with the lazy loading policy.
So i added copy of my module:
     <cairngorm:ParsleyModuleDescriptor objectId="test"
          url="TestModule.swf"
          applicationDomain="{ClassInfo.currentDomain}"
     />
     <cairngorm:ParsleyModuleDescriptor objectId="testbis"
          url="TestModuleBis.swf"
          applicationDomain="{ClassInfo.currentDomain}"
     />
Set them both with a basicLoadPolicy, and tries to dispatch a message to only one of them using the ModuleId metatag. I then noticed that both modules received the message and not only the one i expected.
I then changed the ModuleMessageInterceptor configuration to dispatch to only one kind of module:
<cairngorm:ModuleMessageInterceptor type="{ OpenViewMessage }" moduleRef="test"/>
and this worked as expected. Only the first module catched the message. I am obiously messing with the ModuleId metatag but i cannot see what's wrong...
I compiled with
-keep-as3-metadata+=ModuleId
but this hasn't changed anything...

How to print text/data in flex 3 using printer???Plz help...

   Hi,
          plz tell me the way to print text/data using printer in flex. I tried the FlexPrintJob class. but it takes object of a container to be printed & prints the visible content of that container(along with scrollbars), bt i want to print all contents of the container(including invisible).
      I have tried to print bitmap image through FlexPrintJob but it takes lot of time for spooling... So plz help me out in printing(fast with all content) in flash
I am using flex 3 (flex Builder 3 IDE).
Thanks in advance!!!

Hi Sagar,
Don't worry You can use the below work around to print all the contents of the Container including the invisible contents under scrolll with out scroll bar..
So what the idea here is we are seeting the container height to full size with out scrolls before sending the container object to printer and as soon as you print the object you are restoring it to the original height with scrolls...so that you can print the full contents without scrolls...
You may have doubt that by chnaging and restoring the size the user may see momentary resize of the container but it is not so as it is a fraction of a second and user cannot notice this change... Give it a try ..I had already run into this problem recently and I have found a work around for this which is as below:
// Here mainContainer is the container or box id the contents of which you want to print
   private function doPrintContainer():void
    var printJob:FlexPrintJob = new FlexPrintJob();
    if(printJob.start() != true) return;
    try
     var mainContainerHeight:int = mainContainer.height;
     //Increasing the height of the desired component to be printed.
     mainContainer.height = mainContainer.measuredMinHeight;
     mainContainer.verticalScrollPolicy = "off";
     //Adding the resized Component to our FlexPrintjob and then sending the print request
     printJob.addObject(this,FlexPrintJobScaleType.MATCH_WIDTH);
     printJob.send();
     //Resizing the component back to normal size
     mainContainer.height = mainContainerHeight;
     mainContainer.verticalScrollPolicy = "auto";
    catch(error:Error)
                 trace("Error : " + error.message);
If this post answers your question or helps, please kindly mark it as such.
Thanks,
