 486 Feature RequestKodak 6800/6850 Add support for Kodak 6850 Closed2013-07-27 Task Description

The Kodak 6850 uses an identical spool format. Somehow obtain sniffs of the printing sequence and update the spooler as necessary.

 485 Feature RequestKodak 1400/805 Add support for the Kodak 805 Closed2013-07-18 Task Description

The 805 uses an identical spool format as the 1400, and is phyiscally an updated model.

Obtain a sniff of a print under Windows, and update the backend to work as appropriate, or write a new spooler if the format is radically different.

Without it, we can't add support.

 476 Bug ReportShinko CHC-S2145 s2145 hangs on subsequent requests Closed2013-07-16 Task Description

The first request succeeds, but subsequent requests hang when trying to talk to the printer.

I suspect what's going on here is that the response buffers we're posting are simply too small and the printer loses its mind.
