Thermal Spectrum is a ZX Printer interface to a thermal printer module, for ZX Spectrum computer.
Building the firmware
First you'll need the compiler. If you're using a Debian-based Linux you can
get it by installing gcc-arm-none-eabi package. Then you'll need the
libstammer library. Build it first, then export environment
variables pointing to it:
export CFLAGS=-ILIBSTAMMER_DIR LDFLAGS=-LLIBSTAMMER_DIRLIBSTAMMER_DIR above is the directory where libstammer build is located.
After that you can build the firmware using make.

Questions
How big is the Printer PCB?
It measures 74 × 47 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Printer use?
39 parts, built around the INA180A2IDBVR(LX) and SN74HCT00DR-JSM. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Printer KiCad files?
From the spbnick/thermal-spectrum repository on GitHub, at the commit this page was made from: the board is printer.kicad/printer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Printer design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
