Flyspray:: Sun, 20 May 2018 02:11:13 +0000 Flyspray::CUPS Dyesub Backends: Recently edited tasks FS#541: Validate Mitsubishi CP-D90 support Solomon Peachy Thu, 28 Apr 2016 22:41:05 +0000 It looks like it's an evolution of the D70 family, with one critical exception -- it appears as if the color/thermal compensation is performed in the printer instead of the driver!

FS#558: Investigate new Sinfonia S3 (CHC-S2245) Solomon Peachy Thu, 22 Dec 2016 03:38:31 +0000 Replacement for the S2145, it's main fature is high capacity (900 print) media.

Initial investigation implies it may require host-side image processing, not unlike the S6145.

FS#601: Figure out a way to add a generic test harness for file parsing Solomon Peachy Thu, 10 May 2018 02:14:19 +0000 Right now there's no way to parse the input files without the printer being attached first.

Would require shimming libusb...

FS#550: Verify support for D707 Solomon Peachy Fri, 07 Oct 2016 02:03:18 +0000 Code's complete, but needs to be verified.


FS#600: Add support for CUPS Command files Solomon Peachy Fri, 27 Apr 2018 15:48:17 +0000 CUPS defines a "command filter" that gives the ability to perform some actions and queries.

  • ReportLevels -- marker-levels and whatnot.  Highly useful.
  • ReportStatus -- Once we get unified reporting in place, will be handy.
  • AutoConfigure -- Allows the PPD defaults to be updated based on printer configuration.  (!!)
  • PrintSelfTestPage -- For printers that support it
  • [and others that don't matter]

There appears to be no way to distinguish betwen a command filter vs print filter via the cmdline or environment.  traditionally these are seperate executables that expect different input data.  I'd like to figure out a way to make the backends detect the command stream vs the normal backend data, and do it all in one executable.

FS#569: Figure out image processing algorithms for CP-98xx family Solomon Peachy Thu, 23 Mar 2017 04:06:21 +0000 They're an older-generation of the D70 family's.  Data tables are unfortunately embedded inside the drivers, which makes this a lot more challenging. Sigh.

(If nothing else, simply obtaining the RGB->YMC conversion/gamma tables would make the printers immediately useful..)

FS#539: Consolidate CW-01 and DNP backends Solomon Peachy Wed, 26 Aug 2015 04:12:50 +0000 There's a great deal of overlap; the main difference is the format of the print job. It may make sense to fold the CW-01 stuff into the DNP backend (including the spool format), but alternatively perhaps just a shared library?

FS#596: Figure out if Citizen CW-02/OP900II are closer to CX or CY series Solomon Peachy Thu, 22 Feb 2018 19:35:06 +0000 ...or if they need their own designation in Gutenprint and selphy_print.

It looks like they don't map entirely cleanly to either for avialable print options, but the real question is the firmware version tests for features.

FS#599: Enhance Magicard driver to allow for different options on the duplex side. Solomon Peachy Sat, 10 Mar 2018 21:54:23 +0000 At minimum, the overcoat hole is different on front vs back (eg smartcard vs magstripe).

Magstripe probably only belongs on the back, smartcard on the front.

Holokote and holopatch likely need to be different too.

FS#597: Allow for aliases in backend names? Solomon Peachy Thu, 22 Feb 2018 19:40:13 +0000 That would allow us to present a 'modern' name for the backend but still provide backwards compatibility.

eg: dnpds40 -> dnp_citizen or mitsu9550 -> mitsu9xxx or mitsup95d->mitsu_p9x

Another approach would be to make things more fine-grained.
