Thermal head damaged, be careful!

Very happy with my devterm, just a bit sad to have damaged the print head.
Prints have noticable stripes where the printing head burned out.

Might be due to changing printer printing density too high and printing too many pictures in a row, as documented in DevTerm/Code/thermal_printer at main · clockworkpi/DevTerm · GitHub

What is the model number or specifications to look for in a replacement?

Thats actually dye from the paper, if you take a cotton swab and isopropyl alcohol you can clean those blobs.
