To output, even if to a screen. If a hacker
says that a program "printed a message", he means this; if he
refers to printing a file, he probably means it in the conventional
sense of writing to a hardcopy device (compounds like `print job'
and `printout', on the other hand, always refer to the
latter). This very common term is likely a holdover from the days
when printing terminals were the norm, perpetuated by programming
language constructs like C's printf(3). See senses 1 and 2 of
