I finally made some time today to figure out (at least initially) how to connect an Adafruit TTL Serial Mini Thermal Printer https://www.adafruit.com/product/600?gc ... R7EALw_wcB https://www.adafruit.com/product/597?gc ... YJEALw_wcB to the IDC10 connector on a ZXpand+ serial connection. I'm still trying to figure it all out based on what I learned connecting a Parallax serial LCD to the ZXpand+ serial connection. I had to use Appendix A - The character set in the ZX81 manual http://www.worldofspectrum.org/ZX81BasicProgramming/ for the Hex characters with the attached printer manual to use in the 1 REM statement.

Re: ZXpand+ Serial - Mini Thermal Receipt Printer
I have not heard of this memotech serial rom. You would need a physical 5vdc Tx pin to connect to the Rx pin on the mini thermal printer. ZXpand+ has the hardware and software with the baud rate to support this.
Re: ZXpand+ Serial - Mini Thermal Receipt Printer
After looking through the Memotech PDF, I believe the Serial TTL mini thermal printer would work with it as the memotech serial device appears to have TXD and RXD pins. You might have to run ground between the memotech serial device and the thermal printer as not to introduce any ground looping issues. You can try and it should work.
