As report viewer need ActiveX control to print the report which was possible in Windows IE only.

But after a long search on google. I have found 2 Solution which will allow you to print in Chrome and FireFox as well.

Solution 1: (Render content in HTML and call Print Command through JavaScript)

Put this code in Head of the page.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js" type="text/javascript"></script>

<script type="text/javascript">

// Linking the print function to the print button

$(document).ready(function () {

$('#printreport').click(function () {

//alert('Hi');

printReport('ReportViewer1');

});

function printReport(report_ID) {

var rv1 = $('#' + report_ID);

var iDoc = rv1.parents('html');

// Reading the report styles

var styles = iDoc.find("head style[id$='ReportControl_styles']").html();

if ((styles == undefined) || (styles == '')) {

iDoc.find('head script').each(function () {

var cnt = $(this).html();

var p1 = cnt.indexOf('ReportStyles":"');

if (p1 > 0) {

p1 += 15;

var p2 = cnt.indexOf('"', p1);

styles = cnt.substr(p1, p2 - p1);

}

});

}

if (styles == '') { alert("Cannot generate styles, Displaying without styles.."); }

styles = '<style type="text/css">' + styles + "</style>";

// Reading the report html

var table = rv1.find("div[id$='_oReportDiv']");

if (table == undefined) {

alert("Report source not found.");

return;

}

// Generating a copy of the report in a new window

var docType = '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/loose.dtd">';

var docCnt = styles + table.parent().html();

var docHead = '<style>body{margin:0;padding:0; line-height: 0.5em;} @page { size: A4; margin: 0;} @media print { html, body { width: 210mm; height: 297mm; }} @media print { footer { page-break-after: always; }} td {padding:0;}</style>';

var winAttr = "location=yes, statusbar=no, directories=no, menubar=no, titlebar=no, toolbar=no, dependent=no, width=900px, height=700px, resizable=yes, screenX=100, screenY=100, personalbar=no, scrollbars=yes";;

var newWin = window.open("", "_blank", winAttr);

writeDoc = newWin.document;

writeDoc.open();

writeDoc.write(docType + '<html>' + docHead + '<body onload="window.print();">' + docCnt + '</body></html>');

writeDoc.close();

// The print event will fire as soon as the window loads

newWin.focus();

// uncomment to autoclose the preview window when printing is confirmed or canceled.

// newWin.close();

};

});

</script>

Control on Page

<input id="printreport" type="button" value="Print" />

<rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt" InteractiveDeviceInfos="(Collection)" ShowExportControls="true" WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt" Height="600px" Width="820px" ShowPrintButton="true">

<LocalReport ReportPath="report.rdlc"> </LocalReport>

</rsweb:ReportViewer>

Solution 2 (Render report content in PDF and call print function.)

Required itextsharp.dll version 5.0

<asp:ImageButton ID="btnPrint" runat="server" OnClick="btnPrint_Click" ImageUrl="https://cdn3.iconfinder.com/data/icons/black-easy/512/535129-print_512x512.png" Height="50px" />

<rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt" InteractiveDeviceInfos="(Collection)" ShowExportControls="true" WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt" Height="600px" Width="820px" ShowPrintButton="true">

<LocalReport ReportPath="report.rdlc"> </LocalReport>

</rsweb:ReportViewer>

using System.IO;

using iTextSharp.text.pdf;

using iTextSharp.text;

using Microsoft.Reporting.WebForms;

protected void btnPrint_Click(object sender, ImageClickEventArgs e)

{

Warning[] warnings;

string[] streamids;

string mimeType;

string encoding;

string extension;

byte[] bytes = ReportViewer1.LocalReport.Render("PDF", null, out mimeType,

out encoding, out extension, out streamids, out warnings);

FileStream fs = new FileStream(HttpContext.Current.Server.MapPath("output.pdf"), FileMode.Create);

fs.Write(bytes, 0, bytes.Length);

fs.Close();

//Open exsisting pdf

Document document = new Document(PageSize.A4);

PdfReader reader = new PdfReader(HttpContext.Current.Server.MapPath("output.pdf"));

//Getting a instance of new pdf wrtiter

PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(

HttpContext.Current.Server.MapPath("Print.pdf"), FileMode.Create));

document.Open();

PdfContentByte cb = writer.DirectContent;

int i = 0;

int p = 0;

int n = reader.NumberOfPages;

Rectangle psize = reader.GetPageSize(1);

float width = psize.Width;

float height = psize.Height;

//Add Page to new document

while (i < n)

{

document.NewPage();

p++; i++;

PdfImportedPage page1 = writer.GetImportedPage(reader, i);

cb.AddTemplate(page1, 0, 0);

}

//Attach javascript to the document

PdfAction jAction = PdfAction.JavaScript("this.print(true);\r", writer);

writer.AddJavaScript(jAction);

document.Close();

//Attach pdf to the iframe

frmPrint.Attributes["src"] = "Print.pdf";

}
