Quick Answer: What Replaced the Citizen CT-S801II?
For many businesses, the Citizen CT-S801III is the natural replacement path for CT-S801II receipt printer configurations. However, the correct replacement depends on the exact CT-S801II part number, interface, color, cutter, display option, receipt paper size, cash drawer setup, operating system, and POS software support.
Do not replace a CT-S801II by model family alone. A CT-S801II with USB may require a different replacement than a CT-S801II with Ethernet, serial, Powered USB, Bluetooth, or another interface. The replacement should match how your POS system communicates with the printer and how your workstation is physically configured.
Citizen CT-S801II vs CT-S801III: What Buyers Need to Know
The CT-S801II and CT-S801III names are often searched together because businesses are trying to determine whether a newer CT-S801III model can replace an older CT-S801II printer. In many cases, the CT-S801III is the better model family to evaluate when replacing older CT-S801II hardware, but the final choice still depends on your exact POS environment.
| Model Family | Common Buyer Intent | What to Confirm |
|---|---|---|
| Citizen CT-S801II | Legacy or existing receipt printer being replaced, repaired, matched, or supported | Exact part number, interface, drivers, paper size, cash drawer cable, cutter/display options, and POS software support |
| Citizen CT-S801III | Current or newer replacement path for many CT-S801II-style receipt printer installations | Correct interface, color, paper compatibility, power supply, driver support, and software compatibility |
| Other Citizen Receipt Printers | Alternative replacement if the exact CT-S801III configuration is not the right fit | Receipt exit style, connection type, countertop space, cash drawer support, print requirements, and POS software approval |

Before You Replace a Citizen CT-S801II
Replacing a POS receipt printer looks simple, but small configuration differences can cause avoidable downtime. The printer may physically look similar, but interface boards, drivers, power supplies, cables, firmware, cash drawer settings, paper width, and software support can vary by exact model.
Confirm These Details First
- Exact model and part number: Check the label on the existing printer, not just the model name from an old invoice.
- Interface type: Confirm whether the printer uses USB, Ethernet, serial, Bluetooth, wireless, Powered USB, or another connection type.
- POS software support: Confirm that your POS software supports the replacement model and driver.
- Operating system: Check compatibility with Windows, Android, iOS, macOS, Linux, or your embedded POS platform.
- Receipt paper size: Confirm receipt paper width, roll diameter, and thermal paper requirements.
- Cash drawer setup: Verify whether your cash drawer opens through the printer and whether the drawer cable is compatible.
- Cutter and display options: If your current printer has a cutter or display, confirm whether the replacement should match that setup.
- Color and physical placement: Confirm whether you need black, white, top-exit, front-exit, or another physical configuration.
- Cables and power supply: Confirm whether the replacement includes the power supply, interface cable, or required accessories.
Common CT-S801II Replacement Scenarios
Replacing a Failed CT-S801II Printer
If your CT-S801II stopped working, the goal is usually to replace it quickly without changing the rest of the POS station. In this case, match the old printer’s interface, paper size, cash drawer support, and software driver requirements as closely as possible.
Upgrading from CT-S801II to CT-S801III
If your business is standardizing on newer Citizen receipt printers, a CT-S801III configuration may be the right path. Before upgrading, confirm that your POS software supports the newer model and that your connection type, driver settings, cash drawer setup, and paper requirements are compatible.
Replacing a Specific Part Number
Some buyers search by detailed configuration, such as a CT-S801II model with 8 dots/mm, 203 dpi, cutter, display, and a specific color or interface. These details matter. A replacement should be chosen by the complete configuration, not just the CT-S801 name.
Changing from USB to Ethernet
Some businesses use a replacement as an opportunity to move from a direct USB setup to a networked Ethernet setup. This can be helpful in some environments, but your POS software, network, and device configuration must support Ethernet receipt printing.
Replacing a Printer That Opens a Cash Drawer
If your cash drawer connects to the receipt printer, confirm drawer cable compatibility and POS software drawer-kick settings before ordering. A receipt printer replacement can affect cash drawer operation if the drawer port or cable setup is different.
Key Features to Consider in a CT-S801III Replacement
- Thermal receipt printing: Designed for standard POS receipt workflows without ink or ribbon.
- POS-focused design: Suitable for retail, restaurant, hospitality, service counter, and checkout environments.
- Interface options: Choose the correct USB, Ethernet, serial, Bluetooth, wireless, Powered USB, or other supported configuration.
- Auto-cutter requirements: Confirm whether your workflow requires an automatic cutter.
- Display options: If your old printer included a display, confirm whether your replacement should include one.
- Cash drawer support: Confirm drawer cable, drawer port, and POS software support.
- Receipt paper compatibility: Confirm paper width, roll size, and thermal paper requirements.
- Driver support: Confirm the replacement model works with your operating system and POS software.

How to Choose the Right Replacement
Step 1: Find the Exact Current Printer Configuration
Look at the label on your existing CT-S801II printer and note the full model number, part number, color, interface, and any option codes. This information is more useful than the general model family name.
Step 2: Identify the Connection Type
Check how your current printer connects to your POS station. A USB printer, Ethernet printer, serial printer, and Powered USB printer are not interchangeable without confirming software and hardware support.
Step 3: Confirm POS Software Support
Your POS software must support the replacement printer model, connection type, and driver. This is especially important for tablet POS, cloud POS, restaurant POS, and legacy Windows POS environments.
Step 4: Match Receipt Paper and Cash Drawer Requirements
Confirm that your replacement printer supports your receipt paper size and cash drawer connection. If your drawer opens through the printer, the replacement must support that workflow.
Step 5: Order the Correct Accessories
Power supplies, interface cables, cash drawer cables, mounting accessories, and other required parts may vary by listing. Confirm what is included before ordering.
