Take a look to the file /etc/samba/printers:

[lp1]
   comment = Direct to LPT1
   browseable = yes
   printable = yes
   path = /tmp
   public = yes
   admin users = nobody
   writable = no
   create mode = 0700
   print command = wave -c 440 1; cat %s >/dev/lp0; rm %s;
   lprm command = rm %s
   lpq command = echo "No entries"; return 0

[lp2]
   comment = Direct to LPT2
   browseable = yes
   printable = yes
   path = /tmp
   public = yes
   admin users = nobody
   writable = no
   create mode = 0700
   print command = wave -c 440 1; cat %s >/dev/lp1; rm %s;
   lprm command = rm %s
   lpq command = echo "No entries"; return 0

You can replace the "wave" command with a script able to emit your
escape code:

                escape_code > /dev/lp0

The command escape_code is

----------------------------
#!/bin/sh
expr c 12 # emits 12 as binary character
expr c 38
expr c 254
.....
-----------------------------

The "expr" command in muLinux is not standard at all. It is able to do
decimal to hex,octal conversions.
Maybe, even "printf" can format characters for this purpose.
