Odoo 销售点：添加按钮以打印不同的收据格式？ 奥多 13

Question

I added another button to print receipt.So, one that prints the default receipt when clicked and another that prints a different template. Here is my code which print the same receipt, my question is how to modify for the second button another template similar to the default with some modifications. Any help please? Thanks.

odoo.define('pos_print.pos_report', function (require) { "use
    strict";
    var screens = require('point_of_sale.screens'); console.log("screens
    : " + screens)
    var gui = require('point_of_sale.gui'); var core =
    require('web.core'); var _t = core._t;
    screens.ReceiptScreenWidget.include({
      renderElement: function() {
            var self = this;
            this._super();
            this.$('.next').click(function(){
                if (!self._locked) {
                    self.click_next();
                }
            });
            this.$('.back').click(function(){
                if (!self._locked) {
                    self.click_back();
                }
            });
            this.$('.button.order-print').click(function(){
                if (!self._locked) {
                    self.print();
                }
            });
    
        },
    
    
    }); });



<templates id="point_of_sale.template" xml:space="preserve">
    <t t-extend="ReceiptScreenWidget">
       <t t-jquery=".button.print" t-operation="after">
           <div class="button order-print">
               <i class='fa fa-print'></i>
               Print POS Order
           </div>
       </t>    </t> </templates>

you need to create new print method in ReceiptScreenWidget:

renderElement: function() {
    var self = this;
    this._super();
    this.$('.next').click(function(){
        if (!self._locked) {
            self.click_next();
        }
    });
    this.$('.back').click(function(){
        if (!self._locked) {
            self.click_back();
        }
    });
    this.$('.button.print').click(function(){
        if (!self._locked) {
            self.print();
        }
    });

    this.$('.button.order-print').click(function(){
        // To print new format
        if (!self._locked) {
            self.myPrint();
        }
    });

},

myPrint: function () {
    // MyNewOrderReceipt is your new receipt template
    // YOUR_PARAMS is parameters required in your template
    var receipt = QWeb.render('MyNewOrderReceipt', YOUR_PARAMS);

    this.pos.proxy.printer.print_receipt(receipt);
    this.pos.get_order()._printed = true;
    this.lock_screen(false);
},

note: this is assuming you are aiming to print the new template directly to printer without preview, if you want to change the receipt screen you need to override ActionButtonWidget.
