Experimente o printf e um shell como o ksh93, zsh ou bash:
for ((i=32;i<127;i++)) do printf "\$(printf %03o "$i")"; done;printf "\n"

Como posso listar todos os caracteres ASCII imprimíveis no terminal?

Você pode fazer:
man ascii
para ver o conjunto completo de caracteres ascii, ou você pode simplesmente executar o comando ascii .
$ ascii
Usage: ascii [-dxohv] [-t] [char-alias...]
-t = one-line output -d = Decimal table -o = octal table -x = hex table
-h = This help screen -v = version information
Prints all aliases of an ASCII character. Args may be chars, C \-escapes,
English names, ^-escapes, ASCII mnemonics, or numerics in decimal/octal/hex.

Mais uma solução awk que um shell (puro) é um, mas aqui está mesmo assim:
awk 'BEGIN{for(i=32;i<127;i++)printf "%c",i}';echo
A página de manual ascii também pode ser usada para obter uma lista assim:

NAME
ascii - ASCII character set encoded in octal, decimal, and hexadecimal
DESCRIPTION
ASCII is the American Standard Code for Information Interchange.
It is a 7-bit code. Many 8-bit codes (such as ISO 8859-1, the
Linux default character set) contain ASCII as their lower half.
The international counterpart of ASCII is known as ISO 646.
The following table contains the 128 ASCII characters.
C program '\X' escapes are noted.

Expandindo a solução do jlliagre (e útil se você não tiver o comando ascii disponível):
awk 'BEGIN {for (i = 32; i < 127; i++) printf "%3d 0x%02x %c\n", i, i, i}'

(observe o ; antes do fechamento da função } )
