Label Printer

The Label Printer is an additional feature that allows to generate custom-sized pdfs, which can then be used ot print labels. The implementation is very simply and can be done in a custom script, so labels can be added to any existing ERPNext doctype.

Usage

Add a snippet like the following in your custom script

frappe.ui.form.on('Item', {
    refresh: function(frm) {
        frm.add_custom_button(__("Create Label"), function() {
            create_label(frm);
        }).addClass("btn-primary");
     }
});

function create_label(frm) {
    // reference to the Label Printer record to be used
    var label_printer = "MyLabel"; 
    // html-content of the label
    var content = "<p>Item: " + frm.doc.item_name + "</p>";  
    var w = window.open(
         frappe.urllib.get_full_url("/api/method/erpnextswiss.erpnextswiss.doctype.label_printer.label_printer.download_label"  
		    + "?label_reference=" + encodeURIComponent(label_printer)
		    + "&content=" + encodeURIComponent(content))
    );
    if (!w) {
        frappe.msgprint(__("Please enable pop-ups")); return;
    }
}

This will create the required label pdf and download it to the browser.
