Connect to power and load paper
- Remove the rear cover by inserting your fingernails or a flat object into the clearances as shown below. Pull out each side one by one.
- With the rear cover removed, connect the power cord and AC adapter to the DC 24V port.
- Turn on the printer, open the front cover, and load paper as shown:
- Close the front cover. The printer automatically cuts any excess paper from the roll.
Connect the printer to your iPad
- Connect a Lightning cable (the charging cable that came with your iPad) to the iPad 2.4A port.
For best results, use a Lightning cable manufactured by Apple. Third-party Lightning cables may not provide a reliable connection or consistent charging.
- Connect the other end of the Lightning cable to your iPad. Your iPad should begin charging.
- On your iPad's home screen, select Settings, then Touch ID & Passcode.
- Scroll down to the Allow Access When Locked section and make sure USB Accessories is toggled on. This helps maintain a stable connection between your printer and iPad.
Connect the printer to your network
The steps in this section are required only if you need to connect a label printer or scale to your Register, or if you have poor Wi-Fi signal strength at your point of sale. Otherwise, skip to connect the printer to your cash drawer.
When connected to your network, the printer functions as the hub for your point of sale hardware. Your iPad connects to the internet, your label printer, and your scale via the receipt printer.
Connect an Ethernet cable
- Connect an Ethernet cable to the LAN port on the printer.
- Connect the other end of the Ethernet cable to an available port on the TrendNet network switch included with your Green Bits hardware kit, or connect directly to your router.

Connect the printer to your cash drawer
The receipt printer controls the automatic opening of your cash drawer when you complete a transaction, even when you don't print a receipt.
- Connect the narrower end of the CD-101A cash drawer cable (included in your Green Bits hardware kit) to the Cash Drawer/Buzzer port.
- Connect the wider end of the cable to the corresponding port on the underside or back of your cash drawer.
