Yes, the LGP-30 uses 7-tack paper tape as well. Normal 8 track paper tape
is 25.4mm, 7 track tape 22.2mm. The latter is absolutely unobtanium... (I
think we have one or two spools).

FYI, from a recent GK thread:
I contacted https://www.adorablesupply.com to get clarification about their
pin feed paper since sometimes people call 9.5" paper 8.5" if it has tear
off
edges. Turns out the guy who responded knew what a Teletype machine
was. I mentioned Teletype restoration as a generic reference and his
response was "I go back a long way with the Teletype 28's"
They also can supply tape in both 11/16" and 1". I suspect they could
also do 7/8". Wonder if they could do gummed back WU style tape?
