If you need a wired receipt printer for a desktop POS setup, this Rongta RP850 review focuses on the details that matter.
It is a practical fit for counter service, kitchen tickets, and other receipt workflows on supported computers.
RP850 Review Summary
The Rongta RP850 makes sense for buyers who want a straightforward 80mm thermal receipt printer with multiple wired connection options and broad desktop OS support.
It is not a general-purpose mobile printer, and the listing is explicit about what it does not support, so the best buyers are those building or maintaining a fixed POS station.
Verdict: this is a solid match if your priority is a desktop-connected thermal printer with auto-cutting and basic flexibility, not wireless convenience or phone-based printing.

Key Features and Specifications of RP850
The RP850 is an 80mm direct thermal receipt printer with an auto cutter and support for both 80mm and 58mm paper widths.
The listing gives a print width of 72mm for one mode and 48mm for the narrower mode, and it specifies 3 1/8 x 203ft direct thermal receipt paper.
Its connectivity is firmly desktop-oriented: USB, serial, and Ethernet are listed, with TCP/IP installation support.
The printer also supports ESC/POS and OPOS commands, which matters for buyers integrating it into conventional POS software.
Other useful details from the listing include:
- Compatible with Windows, Mac, and Linux
- Includes a USB flash drive with a user guide and driver setup guide
- Mac users are directed to read the included manual before downloading drivers
- Built-in sound and light indicator for order reminders
- Reminder sound can be turned off with the printer tool
- Wall-hanging design with two mounting holes on the bottom
- DIP switches on the bottom for settings such as auto-cutter, languages, sound-light indicator, and print density
The most important limitation is also spelled out clearly: it does not support Wi-Fi or Bluetooth, and it is not positioned for iPhone, iPad, Android phones, or tablets.
It is also not listed as compatible with Square, Clover, Chromebook, UberEats, Grubhub, DoorDash, Postmates, Upserve, Shopify, GloriaFood, or Lightspeed.

Who Should Buy RP850?
Buy the RP850 if you are building a fixed checkout lane, back-of-house ticket station, or desktop-based receipt workflow and want a printer that speaks standard POS language.
The combination of USB, serial, and Ethernet support makes it especially appealing for businesses that already have a reliable computer at the point of sale.
It also suits buyers who want a printer that can be mounted out of the way and tuned through hardware switches and printer tools rather than app-based controls.
The sound and light reminder feature may be useful in noisier service areas where a visual or audible cue helps staff notice new orders.
Skip it if your setup depends on wireless printing, mobile devices, or platform-specific app ecosystems.
If you need something for a phone, tablet, or a cloud-first consumer POS stack, the listing suggests this is the wrong tool.
Thermal Printing and POS Setup of RP850
Wired Connectivity Matters
The RP850 is built around wired communication, not convenience-first wireless pairing.
That is a strength for stable counter systems and a drawback for mobile or temporary setups, because your placement is tied to cable runs and a nearby host device.
Paper and Cutter Behavior
Support for 80mm and 58mm paper widths gives the printer some flexibility, and the auto cutter is a meaningful practical upgrade over manual tear-off workflows.
For receipt-heavy use, that combination is more important than decorative features.
Software and Command Compatibility
ESC/POS and OPOS support make the printer easier to place into standard retail or hospitality software.
The included driver materials and manual-based setup approach suggest a product aimed at buyers who expect to configure rather than simply unbox and print.
Front-Desk and Kitchen Use
The sound and light indicator is a small but relevant feature for restaurants and service counters.
If you want a printer that can signal new work in a busy environment, that is useful; if you do not, the feature can reportedly be disabled.
Alternatives to RP850
If you want similar desktop receipt-printing hardware, these Amazon search pages are the most credible starting points:
- Epson thermal receipt printer
- Star Micronics receipt printer
- Bixolon receipt printer
- Zebra label and receipt printer
These alternatives are worth comparing if you want a different mix of brand familiarity, software support, or integration ecosystem.
The right choice usually comes down to whether your POS stack prefers Epson-style, Star Micronics, Bixolon, or other desktop receipt hardware.
Is RP850 Worth It?
The RP850 is worth it if you want a practical wired thermal receipt printer for a desktop POS environment and you are comfortable with its connectivity limits.
It is less compelling if you need wireless freedom, phone compatibility, or a consumer-friendly setup path.
For the right buyer, the value is in the basics done clearly: auto cutting, multiple wired interfaces, standard receipt paper support, and desktop OS compatibility.
If that matches your workflow, this looks like a reasonable, focused choice.
