I want disable all the buttons from POS except "Pagos" button after push the button "Cliente" and enable after push again the button "Pagos" Like the image

I try inherited the js file, but the button customer but doesn't works

restaurant.Printer.include({
    init: function(parent,options){
        this._super();
    },
    print: function(receipt){
        var self = this;
        this._super();
        $('.set-customer').prop('disabled',true);        
    },
});
