Cause : Edit Printer settings not responds as for the Edit mode to get enabled, the below API should give expected results : API : GET /api/v1/settings/printer_settings Response : {"DYMO LabelWriter 450": {"printer_system": "al_print", "orientation": "portrait", "printer_metadata": {shelf_row_value: 'A', shelf_level_name: 'leve', shelf_row_name: 'Row', shelf_level_value: '3'}, "font_size_coefficient": 0.9, "print_while_scanning_box_contents": false, "manufacturer": "Dymo", "is_active": true, "printer_driver_config": "dymo_lw_450_series_300X300dpi", "printer_name": "DYMO LabelWriter 450", "shelf": "A1-0001", "label_height": "2.125", "print_while_scanning": true, "user_id": "82464b8c-5d90-444a-90c0-dd488170985f", "barcode_type": "CODE39", "label_type": "Dymo 30270 | 2.125 x 3.5", "label_width": "3.5", "print_type": null}} The edit mode disable error is due to null values for printer_system , is_active,
Resolution : 1. Login as user as per given procedure to test at the user end and reproduce the cause -
2. Two ways to resolve the functionality : First - We can either call /SET /api/v1/settings/printer_settings and feed the right values using tools like POSTMAN .
Second - Start server locally using below commands :
1. npm run build:css
2. npm run start:js
Login as user with the printer connected using admin as shown above and open accelerprint printer settings . Now, in file src/views/pages/settings/PrintSettings/al_print/index.js : set this.state.editMode to false (line 62) temperorily to make the Edit form visible. Once we get Edit form visible , just save the settings as per the label size and click on Save button. Once the API /SET /api/v1/settings/printer_settings saves the right settings , the /GET api will give the right results. Now, revert the change for "this.state.editMode" at line 62. Now, the API changes will fix the edit mode settings and user will be able to toggle the edit settings
