RawBT

RawBT is a printing tool designed for the Android operating system. It enables users to print on thermal paper and supports a wide range of printer models, with connectivity options including Bluetooth, USB cables, and more. The printing process is straightforward: simply follow the on-screen prompts to print your content quickly and easily. Furthermore, the app does not collect any personal user data or information about the content being printed, ensuring your privacy and security. It is also highly lightweight, so it won’t place a significant burden on your phone’s resources.

Features

This application provides printing services, allowing you to easily print documents from websites or other apps using standard or specialized interaction methods. It also supports the convenient printing of text and images directly from your mobile device.

To print, simply look for the "Print," "Share," "Send," or "Open" option within any application, select RawBT, and follow the on-screen prompts. This functionality works across a variety of apps, including web browsers, email clients, photo galleries, and file managers.

The app supports multiple connection types, including Bluetooth, USB (if supported by your hardware), and Ethernet or Wi-Fi using the AppSocket protocol on port 9100.

The app is compatible with a wide range of printer models. Rather than relying on specific printer models, it utilizes appropriate graphical printing commands. Supported commands include GS v0 (compatible with most printers), ESC * 33 (for Epson-compatible printers), ESC X or ESC X 4 (for Star-compatible printers), and several others.

Pros and Cons

Pros:

By embedding a special link, websites can trigger direct printing to a thermal printer connected to your phone; the app runs silently in the background, indicated only by a small icon in the notification bar.

Purchasing a license removes the notification text that otherwise appears on every printed receipt. The developer has confirmed that both the free and paid versions offer the same printing speed and quality.

As noted in user reviews, a lifetime license is available as an alternative to a monthly subscription.

Cons:

According to user reports, adjusting the TrueType font size does not appear to have a noticeable effect.

FAQs

How much does RawBT cost? Are there any in-app purchases?

Does RawBT collect or share my data?

According to the developer, RawBT does not collect any data, nor does it share data with third parties.

Which printers and connection methods does RawBT support?

RawBT can connect to printers via Bluetooth, USB (provided the hardware supports it), Ethernet, or Wi-Fi (using the AppSocket protocol on port 9100).

Conclusion
