This tutorial sets up a receipt printer and the cash drawer plugged into it, and then lists how to add the other devices. It takes about 5 minutes. ## Before you start - The printer is switched on, has paper and is connected to the computer (USB, serial cable or network). - For a USB printer, its driver is installed in Windows, so it appears in the Windows printer list. - You are signed in on the Desktop app. Any signed in cashier can open Devices. ## Steps ### Open Devices On the Home screen, click the **Devices** tile (**Printer, drawer, scanner**). ### Choose how the printer connects Under **Receipt printer**, choose **USB / Windows** for a printer installed in Windows, **Serial COM** for a serial or USB-serial cable, **Network LAN** for a printer with an IP address, or **No printer** to turn printing off. ### Pick the printer For **USB / Windows**, choose the printer in **Windows printer**. If the list is empty, install the printer driver in Windows and reload the page. For **Serial COM**, choose the **COM port** and **Port speed (baud)**. For **Network LAN**, type the **Printer IP address** (port 9100). ### Set paper and printing options Choose the **Paper width**: 58 mm or 80 mm. Turn on **Print automatically** to print after every payment, **Cut paper** if your printer has an auto cutter, and **Open cash drawer** to open the drawer when a payment includes cash. ### Print a test page Click **Test print**. The printer prints a page titled **BAKASIR TEST PRINT** and Bakasir confirms **Test page sent to the printer**. ### Test the cash drawer Click **Open drawer**. The drawer connected to the printer opens and Bakasir shows **Open drawer command sent**. ### Save the settings Click **Save**. Bakasir shows **Device settings saved**. **Test print** and **Open drawer** also save what you entered. Receipts follow the layout set in the Portal under **Settings → Receipt**, including logo, header, footer and online receipt QR code. ## Cash drawer The drawer is connected to the receipt printer and opens through it. It opens after a cash payment when **Open cash drawer** is on, and after cash out and petty cash entries. With **Print automatically** off, the drawer still opens on cash sales if **Open cash drawer** is on. ## Barcode scanner A USB scanner that works like a keyboard needs no setup. Scan on the POS screen, on Price check, or in label search. For a serial scanner, choose its port under **Barcode scanner** in **Serial scanner port**. **Last scan** in Diagnostics shows the last code Bakasir received. ## Scale For products sold by weight, choose the scale's **COM port** under **Scale** and set the **Port speed (baud)**. The page shows the weight, for example **Reading 1.250 kg**, or **No reading yet**. At the POS, open a line and press **Read from scale**. If no weight has arrived, Bakasir says **No scale reading yet**. ## Customer display Turn on **Customer display** and choose the **Monitor** to show the cart and total to the customer on a second screen. It also shows the QRIS code during QRIS payment, **Thank you** with the change after payment, and a slideshow with your message when the cart is empty. With only one monitor, the display opens in a normal window. Set the slideshow images, seconds per image and the thank-you message in the Portal under **Settings → POS → Customer display**. A **VFD pole display** (a small two line display) can be connected on a COM port. It shows the last item and the total. ## Kitchen printer Under **Kitchen printer**, choose the printer for kitchen tickets, or **Same as receipt printer** when you have only one. Tickets print when you send an order with **To kitchen**. ## Label printer Under **Label printer**, choose the printer, the language (**ZPL**, **TSPL** or **ESC/POS**) and the label **Width (mm)** and **Height (mm)**. ZPL and TSPL suit Zebra, TSC and Xprinter label printers. With ESC/POS, labels print on the receipt printer. Labels are printed from the **Print labels** tile, see [Sales history, orders and tools](https://docs.bakasir.com/en/docs/desktop/sales-and-tools.md). ## Diagnostics At the bottom of Devices, click **Run tests** to check the **Server** connection (shown in milliseconds) and the **Offline queue** (sales waiting and failed). **Open log folder** opens the folder with the log files, which support may ask for. ## Tips - **Printer says it did not respond?** Check power, paper and the cable, then try **Test print** again. The message is **The device did not respond**. - **Port could not be opened.** Close any other program that uses the same COM port. - **Switch printers?** Change the settings and press **Test print** again. No sales are lost. ## Next steps - [Sell at the counter](https://docs.bakasir.com/en/docs/desktop/selling.md) - [Cash, X and Z reports](https://docs.bakasir.com/en/docs/desktop/cash-and-reports.md) - [Settings: receipts in the Portal](https://docs.bakasir.com/en/docs/portal/settings.md)
