A few months ago I received a semi-official documentation dump from
Sinfonia. Thanks to that information, Gutenprint now claims full
support for both the S1245 and S6245. These models required new
backends, and last night I committed the last of the necessary changes.
Both printers should now work -- in theory, anyway.
As I don't own or have access to either printer, this code has received no testing whatsoever, and as such might result in kittens swallowing the earth with impeccable wide-eyed cuteness as they mew and cry out for belly rubs. Oh, the humanity!
If there's someone out there who wouldn't mind donating a printer to the cause, or at least be willing to go a few rounds of testing, drop me a line.
Do it for Free Software. Do it for World Peace. Do it for Kittens.
