Yes, the Brother TZe-231 cartridges are compatible with the Brother P-touch H110. Your P-touch H110 supports TZe tapes with a width of 6 mm to 12 mm. You can therefore use the TZe-231 cassettes without any problems.

TZe-231 vs. TZ-231
TZe tapes are the newer, more environmentally friendly ones according to https://support.brother.com/g/b/faqend.aspx?c=ch&lang=de&prod=h75euk&faqid=faqp00001540_000.
Hello HanniBaur
On the machine, next to the display of the P-Touch 65, it says "M-Tape", doesn't it? If that's right, the TZ tapes don't fit this P-Touch. That would be M-Tape, these here: https://support.brother.com/g/b/colist.aspx?c=us&lang=en&prod=65eus&cao=tape
