Hello @mjunes,
My apologies for the delay in respond to your ticket, I was doing some test and modifications, please replace the piece of code of the printForm routine with the following one:
<script>window['printForm']=function(selector){function _cloneCanvas(newCanvas,oldCanvas){var context=newCanvas.getContext('2d');newCanvas.width=oldCanvas.width;newCanvas.height=oldCanvas.height;context.drawImage(oldCanvas,0,0);};function _getStyles(){var r='';$(document).find('link[type*="css"],style').each(function(){r+=this.outerHTML;});return r;};function _callPrint(w){if(w&&w["printMe"]) w["printMe"]();else setTimeout(function(){_callPrint(w);},50);};try{if(typeof jQuery!='undefined'){if(typeof selector!='undefined'){var $=jQuery,f=$(selector),c,e,h,t,w,d;if(f.length){c=f.clone();c.find('script').remove();c.find('input').each(function(){e=$(this);if(typeof e.prop('checked')!='undefined') e.attr('CHECKED',e.prop('checked'));e.attr('value',e.val());});c.find('SELECT').each(function(){e=$(this);t=f.find('[id="'+e.attr('id')+'"] option:selected').text();e.replaceWith(t);});c.find('TEXTAREA').each(function(){e=$(this);t=e.val();e.replaceWith(t);});h=c[0].outerHTML;w=$('#cff_iframe_for_printing');if(w.length==0){w=$('<iframe id="cff_iframe_for_printing" name="cff_iframe_for_printing" style="display:none;"></iframe>');w.appendTo('body');} d=w[0].contentWindow.document;d.write('<body>'+_getStyles()+h+'</body>');setTimeout(function(){d.close();$(d).find('canvas').each(function(i,e){_cloneCanvas(e,f.find('canvas:eq('+i+')')[0]);});var ua=window.navigator.userAgent,msie=ua.indexOf("MSIE ");if(msie!==0){w[0].contentWindow.document.execCommand('print',false,null);}else{w[0].contentWindow.print();}},1500);}else{throw"Form's selector is incorrect";}}else{throw'Requires the selector';}}else{throw'Requires the jQuery framework';}}catch(err){if(typeof console!='undefined') console.log(err);}};</script>
Best regards.
