Cut and paste.  Consider the S/360 Assembler (F) manual:

http://bitsavers.org/pdf/ibm/360/asm/C26-3756-2_Assembler_F_Programmers_Guide_196711.pdf

Look at PDF page 10.   Note the box at the bottom of the page and how
it's not even perfectly horizontal at the borders.  In fact, it looks to
be hand-drawn.  I suspect that things were put together the old
way--with scissors and rubber cement.

I recall that in a real professional publications operation, several
typewriters with various fonts (and sizes) were used.  And then there
were the T-square and ink graphics people...
