Migrating to JSPrintManager 5.0 from older versions

The brand new JSPrintManager 5.0 is compatible with older versions but a few modifications must be done to get JSPM v5.0 working on an existing project using older versions.

Migration steps (valid for any older version)

• Be sure you refresh the script file references to use JSPrintManager.js 5.0

• Be sure to install on each of the client machines the JSPM App 5.0 available at https://neodynamic.com/downloads/jspm (JSPM App 5.0 run side by side with older versions)

Migration steps depending of the older version

Migrating from v4.0

• No extra steps are required!

Migrating from v3.0

• Just be aware that WIA & Old TWAIN 1.x scanner drivers are supported only if the client installs the 32-bit version of the JSPM App.

Migrating from v2.0

• Serial Port Data Bits is now an enumeration called JSPM.Serial.DataBits
• JSPM.WSStatus.Blacklisted renamed to JSPM.WSStatus.Blocked

Migrating from v1.0

• Serial Port Data Bits is now an enumeration called JSPM.Serial.DataBits
• JSPM.WSStatus.Blacklisted renamed to JSPM.WSStatus.Blocked
• JSPM websocked is available when JSPM.JSPrintManager.start() succeed. A sample code for v1.0 would look like the following:

<script type="text/javascript">
    JSPM.JSPrintManager.start()
                .then(_ => {
                    var cpj = new JSPM.ClientPrintJob();
                    cpj.clientPrinter = new JSPM.DefaultPrinter();
                    var my_file = new JSPM.PrintFile('/images/penguins300dpi.jpg', JSPM.FileSourceType.URL, 'MyFile.jpg', 1);
                    cpj.files.push(my_file);
                    cpj.sendToClient();
                })
                .catch((e) => {
                  alert(e);
                });
</script>

In v5.0, JSPM Websocket status must be verified in the JSPM.JSPrintManager.WS.onStatusChanged event. The above code for v1.0 can be converted to v5.0 as follows:

<script type="text/javascript">

    JSPM.JSPrintManager.auto_reconnect = true;
    JSPM.JSPrintManager.start();
    JSPM.JSPrintManager.WS.onStatusChanged = function () {
        if (JSPM.JSPrintManager.websocket_status == JSPM.WSStatus.Open) {
            var cpj = new JSPM.ClientPrintJob();
            cpj.clientPrinter = new JSPM.DefaultPrinter();
            var my_file = new JSPM.PrintFile('/images/penguins300dpi.jpg', JSPM.FileSourceType.URL, 'MyFile.jpg', 1);
            cpj.files.push(my_file);
            cpj.sendToClient();
        }
    };

</script>
