Commodity label printing (code printer)

Recently I do a commodity label printing needs, because to meet the business side of warehousing, you can print labels to record the warehousing of the goods code, so I began to investigate, here need to install Lodop control and your link to the printer driver, do not!!

The Lodop print control is a browser plug-in that is tightly integrated with the browser to achieve local printing, and is an interaction embedded in the browser. (Applicable browser: Ie series, Firefox 51 and history version, Google 44 and history version. (New Versions of Firefox and Google no longer support THE NP plugin, nor can lodop be used)
C-lodop printing service is to provide services to solve the web printing, get rid of the dependence on the browser, to solve the new Google (version 45 and later), 64-bit Firefox, Edge and other browsers no longer support the Lodop plug-in, C-LoDOp printing service support all browsers

After starting the project, you need to install this control, and then click get my lodop in the lower right corner to install the official loDOp control to use.

Control website:www.lodop.net/demo.html

Here 9999 refers to my computer installed loDOp control port number, I set 9999, the default is 8000, you can click to change the Settings

The printer we are linking is Argox CP-2140 PPLB, which can be used after the driver is installed, according to the setting of printer preferences

To make the corresponding label size. Next, start to configure the printed fields in your project

1 save the official lodopfuncs. js file to a directory, such as myProject\ SRC \assets\ lodopfuncs. js

2 Modify the lodopfuncs. js file and add export {getLodop} at the bottom of the file. / / export getLodop

3 import the module in the file where the printing event handler function is located. In the printing event function, call getLodop to obtain the LODOP object variable, write your own printing function according to the official tutorial, and output through PRINT, PREVIEW and PRINT_DESIGN

//= =本JS是加载Lodop插件及CLodop服务的综合示例，可直接使用，建议看懂后融进自己页面程序==

//= =判断是否需要CLodop(那些不支持插件的浏览器):==

        }
        return false;
    } catch (err) {
        return true;

//= =引用CLodop的主JS,用双端口8000和18000(以防其中一个被占):==

    var JS1 = document.createElement('script');
    JS1.src = 'http://localhost:8000/CLodopfuncs.js?priority=1';

    CLodopIsLocal = !!((JS1.src + JS2.src).match(/\/\/localho|\/\/127.0.0./i));

    if (JS1.attachEvent) {
        CLodopJsState = 'loading';
        var onChange = function () {
