Exaclty the title.
I know char(177) returns the plus/minus symbol but can't work out how to get it to display when matlab outputs to the command window.
fprintf('The measured volume of %fmm^{3} \x177 %fmm^{3} is equal to\nthe specified volume of %fmm^{3} \x177 %fmm^{3},\nand therefore the object passes quality inspection and can be released.\n',Vtot, DeltVrounded,VSpec,DeltaVSpec);

Since the data you are printing is of character class, use the c conversion in the formatting operator for that data, e.g., '%c':
a = 10;
b = 1.5;
plus_minus_char = char(177);
fprintf('The measured whatever of %f %c %f is equal to the whatever ...',a,plus_minus_char,b)

pmchar=char(177);
fprintf(['The measured volume of %fmm^{3} ' pmchar '%fmm^{3} is equal to\nthe specified volume of %fmm^{3} ' pmchar '%fmm^{3},\nand therefore the object passes quality inspection and can be released.\n'], ...
Vtot, DeltVrounded,VSpec,DeltaVSpec);
I'd probably write the format string as a variable to be more readable, but that's just a style nit.
