从p：datatable打印所有页面

Question

                         <p:outputPanel autoUpdate="false" id="previewDataPanel" rendered="#{customReportController.previewData}">
                    <p:dataTable id="tbl" value="#{customReportController.data}" var="it" 
                                 paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink} {LastPageLink} {Exporters}"
                                 paginator="true" rows="49" paginatorPosition="top">
                        <f:facet name="{Exporters}">
                                <p:commandButton id="print" value="Print All Data" icon="ui-icon-print">
                                    <p:ajax event="click"  update="tbl"  />
                                    <p:printer target="tbl" />
                                </p:commandButton>
                            <h:commandLink>
                                <p:commandButton id="pdf" value="Pdf" icon="ui-icon-print"></p:commandButton>
                                <p:dataExporter type="pdf" target="tbl" fileName="report" />
                            </h:commandLink>
                            <p:spacer></p:spacer>
                            <p:spacer></p:spacer>
                            <h:commandLink>
                                <p:commandButton id="csv" value="Csv" icon="ui-icon-print"></p:commandButton>
                                <p:dataExporter type="csv" target="tbl" fileName="report" />
                            </h:commandLink>
                            <p:spacer></p:spacer>
                            <p:spacer></p:spacer>
                            <h:commandLink>
                                <p:commandButton id="xls" value="Excel" icon="ui-icon-print"></p:commandButton>
                                <p:dataExporter type="xls" target="tbl" fileName="report" />
                            </h:commandLink>
                        </f:facet>
                        <p:columns value="#{customReportController.columnNames}" var="data" columnIndexVar="i">
                            <f:facet name="header">
                                <h:outputText value="#{data}" />
                            </f:facet>
                            <h:outputText value="#{it[i]}" />
                        </p:columns>
                    </p:dataTable>

这是我的代码。我想打印来自Datatable的所有数据。其他出口商工作正常，但当我尝试打印时，它只打印当前页面。
