By clicking and buying a thermal printer via these links you will be supporting this project. 😀
Thermal printers are completely silent when not in use, and use no ink.
No startup time. Lightning FAST. ⚡️
Small enough to keep on your desk within easy reach.
Epson's Mac, Windows and Linux drivers allow regular printing from e.g. MS Word, Pages, Photos etc.
58 or 80mm paper width. 🖨
If you don't require compatibility with the Free42 calculator emulator, then most any USB thermal printer should work with Print42.
