I'm having big problems printing on a RICOH Aficio SP C240DN (a color laser printer). CUPS/OpenPrinting doesn't have a driver for exactly this printer.

There are similar numbers but not 240DN. It also seems there is no PPD file for this printer, as it doesn't accept PostScript at all. There are only so-called, but no PPD as opposed to slightly older models from RICOH (320DN for example).

The technician at the company where I bought the printer said that DDST is a stripped-down version of PCL6. The connection to the printer works, I can access the web interface for management, I can print test pages via buttons on the printer or via the web interface. If I try any other driver (320DN for example), the printer shows that it is receiving data, the spool on the computer is processing, and then it just thinks the job is finished and done but the printer does nothing.

I'm planning to return it, but was wondering if somebody could explain a bit about drivers (what is DDST?), and if somebody knows if there is any chance that such driver for Linux will be out in any time soon. I'm actually ready to donate a small amount to somebody who would hack an open-source driver (for CUPS). I am currently working on a protocol specification for the Ricoh C240DN. Sadly it's quite different to older BW printers like the SP 100, as it doesn't use PJL headers. It uses banded JBIG images to transfer the data. I can already generate that JBIG data, only the undocumented headers which take place of the PJL headers in the SP100 prove to be quite difficult to reproduce.

I will post a link to my specs here, when I have publishable results. UPDATE: are my preliminary results. I still need to decode the GDIJ data, if anyone could be any help to me, don't hesitate to contact me. GDIJ at least contains paper weight information and maybe print time and date, which I just can't figure out.

I am having the twain drivers(Mac Compatibility) of the twain scanner(panasonic). I installed the divers into my Mac machine and the drivers were installed in the path: Library ▸ Image Capture ▸ TWAIN Data Sources folder.

Ddst Twain Driver For Mac Pro

After the installation of the drivers I tried connecting the Twain scanner(Panasonic) to my mac machine. I tried to view the connected scanner in Image capture app and it shows device list as empty. Even I tried with checking the scanners connected in printers and scanners there also shows no scanners connected. I went through some questions in SO's where they say to for detecting the Twain scanners have to use Twain interface. But my requirements is I want to make the twain drivers detectable by Image capture and want to see the Twain scanner in Image Capture app. Any suggestions: How can I make the twain comparable scanners detected by Image Capture app?
