Printing.  Works for me on desktop Safari.  Same code won’t work on iOS Safari.

Not a lot of code:

===================================

            //"Print" order button on orderItemList page
            $('#orderItemList .toolbar .printButton').live('click', function(event) {
                                //test for pending (Submit) or actual
                                if ($('#orderItemList .tabbar li').last().text() == "Submit") url = "printableOrderHTML.php?u="+dopeArray[0]+"&c="+dopeArray[1]+"&o="+dopeArray[2];     
                                else url = "../ReceiveIt/printableOrderHTML.php?u="+username+"&c="+dopeArray[1]+"&o="+orderNo;
                                bPrint(url);                    
                        });


            //Print function caller
            //        SAFARI VERSION DEPENDENT - assumes "sVersion" has correct Safari version
                        var iframe;
            function bPrint(url) {
                if (sVersion > "5.0.6")
                    if ($('iframe').html() != null) $('iframe').remove();       // newer Safaris require this done here

                iframe = document.createElement("iframe");                                              // create an iframe so that no window pops up
                document.body.appendChild(iframe);                              // insert the element to the DOM 

                aSp = 0;
                $.ajax({
                    url: url, 
                    success: printCallback
                });            
            } 

                        function printCallback(data) {
                                var error=/Error:/g;
                                if (error.test(data) == true) {
                                        $('#error #results').html(data);
                                        jQT.goTo('#error','slideleft');
                                }
                                else {
                                        iframe.contentWindow.document.write(data);                                              // write the HTML to be printed
                                        iframe.contentWindow.print();                                   // print it
                                        if (sVersion <= "5.0.6") 
                                                $('iframe').remove();                                       // older Safaris get this done here, where it should be
                                        return true;    
                                }
                        }

==============================


…as I said, desktop Safari likes this just fine.
In iOS, I get a blank preview page.
Apparently I’m not the only one:

All iOS12 simulator devices give me a blank page.
