FS#520 - Investigate Sony UP-CR20L aka DNP SL-20

Sony sold their printer line to DNP, which rebranded these two models.

Investigate their Spool format, and find out if they need an intelligent backend.

CR10L uses a spool format similar to the UP-DR150/200. The actual contents of the file are different, but it appears as if the existing backend should work.

CR20L uses a totally different file format than the CR10L, 'PJL' with a 'SONY-PDL-DS2' sub-language. (PJL is an HP printer thing)

Haven't investigated the SL-10/20, but I can't imagine DNP rewriting the firmware to use a different command language.

Theoretically, the backend is now extended to handle the CR10L.

Still need to update the gutenprint code.

Gutenprint code is updated.

The Sony UP-D897MD & UP-X897MD models also use PJL with SONY-PDL-DS2.

CR20L job format decoded, backend parser written. Need to write Gutenprint's side of things, and of course, still need a tester...

Gutenprint code written. Just need a tester (and USB PIDs)

Fixed some bugs in frontend and backend for the CR20L (and other UPneo models) In theory we should be able to spool a job properly now, but status readback requires a lot more work.

Firmly in the "need testers" territory now.

backend written and works for the UP-DR80MD. Just needs testing on the CR20L.

Landed a pile of bugfixes in gutenprint and selphy_print that would affect CR20L.
