How do I populate a popup window with data from the parent window

Question

I am brand new to JSF so please help me. I have a JSF page where users enter some search criteria and it displays the results in a matrix table. I need to have a PRINT button or link on this page that pops up a new window that displays the same data but in a printer-friendly format.
The parent page is already created and works fine. Now, what is the best way to populate the same data in the popup? The data is stored in a hashmap and retrived by a managed bean with session scope. Below is the XHTML code for displaying the table in the parent page.
<tbody>
                         <c:forEach items="#{inventoryManagedBean.inventoryColors}" var="row">
                              <tr id="matrixColor">
                                   <c:forEach items="#{inventoryManagedBean.sizeList}" var="column" varStatus="cellStatus">
                                        <c:if test="#{cellStatus.index == 0}">
                                             <th width="70px"><h:graphicImage value="../graphics/styles/#{row.color}.jpg"
                                                  alt="#{row.color}" width="70" height="40"></h:graphicImage></th>
                                             <th width="100px"><h:outputText value="#{row.colorDescription}" />
                                             <h:outputText value="#{row.color}" /></th>
                                        </c:if>
                                        <td width="70px"><c:if
                                             test="#{inventoryManagedBean.inventoryMap[row.color][column.size] != null}">
                                             <c:if test="#{inventoryManagedBean.inventoryMap[row.color][column.size].label != '-1'}">
                                                  <span class="matrixText"><h:outputText
                                                       value="#{inventoryManagedBean.inventoryMap[row.color][column.size].label}"
                                                       title="#{inventoryManagedBean.inventoryMap[row.color][column.size].title}" /> </span>
                                                  <t:htmlTag value="br" rendered="#{userManageBean.user.loggedIn}" />
                                                  <a4j:region renderRegionOnly="false">
                                                       <h:inputText
                                                            value="#{inventoryManagedBean.inventoryMap[row.color][column.size].quantityOrdered}"
                                                            rendered="#{userManageBean.user.loggedIn}" maxlength="6" size="6">
                                                       </h:inputText>
                                                  </a4j:region>
                                             </c:if>
                                             <h:outputText value="Call"
                                                  rendered="#{inventoryManagedBean.inventoryMap[row.color][column.size].label == '-1'}" />
                                        </c:if> <h:outputText value="N/A"
                                             rendered="#{inventoryManagedBean.inventoryMap[row.color][column.size] == null}" /></td>
                                   </c:forEach>
                              </tr>
                         </c:forEach>

Answer 1

call javascript window.open("pagename"); & add some printer button there,
and put rendered attribute to button & in backing bean generate boolean getter setter for variable use same variable in jsp printer button in rendered attribute, in bean constructor pass some parameter throuh jsp page,
if parameter is match then it rendered attribute to true for button else not,
it means that in parent window you can not see printer button, but in same window in popup you will see printer button,
good luck
<h:commandButton rendered="#{bean.renderedButton}"/>
bean
private boolean renderedButton= false;(generate getter setter)
also pass parameter from UI to bean constructor
