A simple UI

Often all print attributes are set with hard-coded script, for example the page headers and footers and may be even paper size and margins.

ScriptX is also frequently used to ensure that a particular printer is used for the print out, for example that the available label printer is used even when the user has a standard laser printer as default.

There are some cases where a number of suitable printers are available and the user should be prompted to select the one of the suitable printers. ScriptX provides methods and properties that allows the available printers to be enumerated and for the attributes of the printer to be queried, for example available papersizes.

// inEnumerator
//
// Returns true if the (string) value is contained in
// any of the items (strings) in the list
function inEnumerator(value, comList) {
    return comList.some(item => item.includes(value));
}

function refreshAvailablePrinters() {

    var printersSelect = document.getElementById("availablePrinters");
    var paperSize = document.getElementById("paperSizes").value;

    // Clear the printers select element
    printersSelect.innerHTML = '';

    // Get available printers and populate the select element
    MeadCo.ScriptX.GetAvailablePrinters().forEach(function (value) {
        try {
            if (inEnumerator(paperSize, MeadCo.ScriptX.Printing.printerControl(value).Forms)) {
                var option = document.createElement("option");
                option.value = value;
                option.text = value;
                printersSelect.appendChild(option);
            }
        } catch (e) {
            console.log("Error: " + e.message);
        }
    });

    // Set the value to the first option
    printersSelect.value = printersSelect.options[0] ? printersSelect.options[0].value : '';
}

window.addEventListener('load', async () => {
    try {
        await MeadCo.ScriptX.InitAsync();

        refreshAvailablePrinters();

        // Event listener for paper size change
        document.getElementById("paperSizes").addEventListener("change", function () {
            refreshAvailablePrinters();
        });

        // Event listener for available printers change
        document.getElementById("availablePrinters").addEventListener("change", function () {
            try {
                // Select chosen printer, then the required paper size
                var p = MeadCo.ScriptX.Printing;

                p.printer = this.value;
                p.paperSize = document.getElementById("paperSizes").value;
            } catch (e) {
                alert("Failed to select the printer: " + e.message);
            }
        });

    } catch (e) {
        app.Messages.PrintErrorBox(e);
    }
});
