Debian dash has a built-in printf which doesn't support \x.
/usr/bin/printf works fine.

$ printf \\xa8\\x51\\x37\\x00 > x ; hexdump x
0000000 785c 3861 785c 3135 785c 3733 785c 3030

$ /usr/bin/printf \\xa8\\x51\\x37\\x00 > x ; hexdump x
0000000 51a8 0037                              
0000004
$ echo -ne \\xa8\\x51\\x37\\x00 > x ; hexdump x
0000000 6e2d 2065 785c 3861 785c 3135 785c 3733
0000010 785c 3030 000a
