Problem with printing after migrating from 3.5 to 4.1

Question

Hello everyone,
I'm currently working on an application that was recently migrated (by someone else) from Flex 3.5 to Flex 4.1 and I discovered the printing doesn't work properly anymore. So I tried to find out what the problem was and after many tries, I came to the conclusion that the problem was within the following line:
printJob.addObject(myPrintView,FlexPrintJobScaleType.MATCH_WIDTH);
(Of course "myPrintView" is not the real name used in the app but that's not important)
I searched on the Internet and this line is supposed to work in 4.1, isn't it? However, the printed version cuts my PrintAdvancedDataGrid approximately in half. I tried to change the width property from myPrintView but the grid is still cut at the same place, its cells are just distorted.
FYI, you can find a part of the code right here:
var printJob:FlexPrintJob = new FlexPrintJob();
                    if (printJob.start()) {
     //A lot of code to build the print view
myPrintView.width=1280;
printJob.addObject(myPrintView,FlexPrintJobScaleType.MATCH_WIDTH);
printJob.send();
myPanel.removeChild(myPrintView);
Any help would be appreciated.

While looking for a solution on the Internet I found some people having troubles because of the structure of their AdvancedDataGrid. My problem doesn't come from any example I've seen but maybe it's still linked to that, so here's an AdvancedDataGrid that's being printed in my app:
                                                <mx:PrintAdvancedDataGrid dataProvider="{dataRayon}" sortExpertMode="true" id="dataGridRayon" width="100%" itemClick="dispatchEvent(new KpiEvent(DATAGRID_RAYON_CLICK,event));" itemDoubleClick="dispatchEvent(new KpiEvent(DATAGRID_RAYON_CLICK,event));" creationComplete="resizeGridRayon();" >
                                                  <mx:columns>
                                                            <mx:AdvancedDataGridColumn id="rownumRayon"  width="25"  sortable="false" labelFunction="getRowNumRayon" fontWeight="bold"/>
                                                            <mx:AdvancedDataGridColumn id="rayonCoRgrp" textAlign="center" width="75" headerText="{resourceManager.getString('rentabilitePanel', 'CODE')}" dataField="co_rgrp_produits" />
                                                            <mx:AdvancedDataGridColumn textAlign="left" width="240" headerText="{resourceManager.getString('rentabilitePanel', 'SOUS_SECTEURS')}" dataField="libelle" id="hTDataGridRayon" />
                                                            <mx:AdvancedDataGridColumn id="rayonMeVenteHt" textAlign="right" width="100" headerText="{resourceManager.getString('rentabilitePanel', 'MONTANT_VENTE_HT')}" dataField="meVenteHt" formatter="{currencyFormatter}" sortCompareFunction="{function(obj1:Object, obj2:Object):int{return mySortFunc(obj1, obj2, 'meVenteHt');}}"  />
                                                            <mx:AdvancedDataGridColumn id="rayonMargeAvtDem" textAlign="right" width="75" headerText="{resourceManager.getString('rentabilitePanel', 'MARGE_AVT_DEM')}" dataField="margeAvtDem" formatter="{currencyFormatter}" sortCompareFunction="{function(obj1:Object, obj2:Object):int{return mySortFunc(obj1, obj2, 'margeAvtDem');}}"  />
                                                            <mx:AdvancedDataGridColumn id="rayonPMargeAvtDem" textAlign="right" width="80" headerText="{resourceManager.getString('rentabilitePanel', 'POUR_MARGE_AVT_DEM')}" dataField="margeAvtDemP" formatter="{pourcentageFormatterFloat}" sortCompareFunction="{function(obj1:Object, obj2:Object):int{return mySortFunc(obj1, obj2, 'margeAvtDemP');}}"  />
                                                            <mx:AdvancedDataGridColumn id="rayonDemarqueHt" textAlign="right" width="100" headerText="{resourceManager.getString('rentabilitePanel', 'DEMARQUE_HT')}" dataField="demarque" formatter="{currencyFormatterFloat1Dec}" sortCompareFunction="{function(obj1:Object, obj2:Object):int{return mySortFunc(obj1, obj2, 'demarque');}}"  />
                                                            <mx:AdvancedDataGridColumn id="rayonPDemarqueHt" textAlign="right" width="85" headerText="{resourceManager.getString('rentabilitePanel', 'POUR_DEMARQUE_HT')}" dataField="demarqueP"  formatter="{pourcentageFormatterFloat}" sortCompareFunction="{function(obj1:Object, obj2:Object):int{return mySortFunc(obj1, obj2, 'demarqueP');}}"  />
                                                            <mx:AdvancedDataGridColumn id="rayonMargeAprDem" textAlign="right" width="100" headerText="{resourceManager.getString('rentabilitePanel', 'MARGE_APR_DEM')}" dataField="margeAprDem" formatter="{currencyFormatter}" sortCompareFunction="{function(obj1:Object, obj2:Object):int{return mySortFunc(obj1, obj2, 'margeAprDem');}}"  />
                                                            <mx:AdvancedDataGridColumn id="rayonPMargeAprDem" textAlign="right" width="115" headerText="{resourceManager.getString('rentabilitePanel', 'POUR_MARGE_APR_DEM')}" dataField="margeAprDemP" formatter="{pourcentageFormatterFloat}" sortCompareFunction="{function(obj1:Object, obj2:Object):int{return mySortFunc(obj1, obj2, 'margeAprDemP');}}"  />
                                                  </mx:columns>
                                        </mx:PrintAdvancedDataGrid>
I also realised I wasn't very clear on the outcome of my doPrint() function. When I said the grid was cut in half, I was talking about half the columns not showing on the printed version, not half the rows. Actually even a column being cut in half. I hope these precisions made my problem a bit clearer and somebody will be able to help me in any way (even just hints).
Thanks for your help.
