Direct RS232 & USB Weigh Scale Interface: Automatic Weight Capture
Eliminate manual weight typing errors and prevent cashier under-billing on fresh produce, meats, sweets, and loose grains:
- Live Weight Stream Capture: System reads stable weight packets directly from COM ports (Baud Rate 9600, 8-N-1 configurable).
- Universal Scale Protocol: Compatible with CAS, Mettler Toledo, Essae, Avery Berkel, and standard Chinese scale protocols.
- Automatic Line Price Calculation: When cashiers select or scan a weighted item, total price updates dynamically in real-time.
- Tare Weight Deduction: Configure container, basket, or bag tare weights to deduct packaging automatically.
High-Speed ESC/POS Thermal Receipt & Barcode Label Printing
Deliver professional receipts and shelf barcode labels with zero print driver lag:
- Direct Raw USB & Network Printing: Bypasses slow Windows print spoolers to fire receipts in less than 0.5 seconds.
- Universal 58mm & 80mm Layouts: Fully customizable templates with your store logo, header, tax details, and return policies.
- Barcode Label Designer: Print product price tags, shelf stickers, and jewelry tags on TSC, Zebra, and Xprinter barcode printers.

RJ11 Drawer Kick & Customer VFD Pole Displays
Complete your counter workstation with automated physical drawer security and clear customer-facing price transparency.
RJ11 Automated Drawer Kicking & 2-Line VFD Pole Displays
Prevent cash register theft while ensuring full customer purchase transparency at every till:

POS Hardware Integration: FAQs
Everything you need to know about setting up printers, scales, scanners, and cash drawers on your PC.
Do I need to buy expensive dedicated POS hardware from InventoryPlus?
No. InventoryPlus is completely open and hardware-agnostic. You can use standard desktop or laptop PCs, USB barcode scanners, standard ESC/POS thermal printers, and third-party weighing scales. You never need to purchase proprietary hardware kits.
How do I configure my electronic weighing scale?
In InventoryPlus Hardware Settings, select your scale's COM Port (e.g. COM1, COM3), set baud rate (typically 9600), data bits, and parity. InventoryPlus tests the live communication and begins streaming weight data directly into your checkout window.
Can I print receipts without the Windows print dialog popping up?
Yes. InventoryPlus includes direct raw ESC/POS printing over USB, Ethernet, and Serial ports. Receipts print instantly and silently the microsecond a payment is authorized with zero print confirmation dialog popups.
How does the cash drawer connect and open?
The electronic cash drawer connects to the receipt printer via a standard RJ11 or RJ12 telephone-style cable. When a cash invoice is finalized, InventoryPlus sends an electrical pulse command through the printer, kicking the drawer open automatically.
Can I design and print custom barcode price stickers?
Yes. The built-in Barcode Designer lets you design custom labels of any dimension (e.g. 50x25mm, 38x25mm) with your business name, product title, retail price, and Code 128 / EAN 13 barcodes for high-speed counter scanning.
