# ddstdecode(1)

ddstdecode - Decode a Ricoh DDST stream into human readable form. **ddstdecode** \[*options*\] \<*ddst-file* **ddstdecode** decodes a Ricoh DDST stream into human readable form.

A Ricoh DDST stream is the printer language used by some Ricoh printers. From what I can tell, it is [pbmtojbg(1)](/pbmtojbg/1.md) wrapped with some PJL.

These are the options that can appear on the command line.

- **-d** *basename*

  Basename of .pbm file for saving decompressed planes.

- **-h**

  Print hex file offsets.

- **-o**

  Print file offsets.

- **-D** *level*

  Set Debug level \[0\].

  Decode an Ricoh DDST stream file created by a Ricoh SP112.

  ```
  $ ddstdecode -h ~/testpage-ricoh-sp112.prn
