FS#596: Figure out if Citizen CW-02/OP900II are closer to CX or CY series http://bugs.shaftnet.org/index.php?do=details&task_id=596 2018-02-22T19:35:06Z Solomon Peachy ...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. ...or if they need their own designation in Gutenprint and selphy_print.

FS#595: When trying to enumerate printers, don't block for a long time when one's busy http://bugs.shaftnet.org/index.php?do=details&task_id=595 2018-02-16T12:11:44Z Solomon Peachy This is a particular problem when we have more than one model of the same printer family attached, and one or more of them are busy doing something -- but we can't query the serial number when the printer is claimed. This may require a two pass approach -- first try to probe everything with minimal timeouts.  If we don't succeed in finding the one we want, re-try the probe with longer timeouts.  In both cases, we shouldn't report a failure until we finish walking the entire list.

FS#589: Fix 8bpp->6bpp color scaling http://bugs.shaftnet.org/index.php?do=details&task_id=589 2018-01-04T01:58:57Z Solomon Peachy Right now we just shift the color data over by 2bits.  It looks like that's naive; it looks like we need some sort of gamma-aware 8->6 mapping on a per-channel basis.  This may require Gutenprint to spit out RGB data, and we perform the YMC conversion at the same time we apply gamma?  (not unlike the Mitsu D70 family..) The printer's "gamma curve" settings don't seem to have any major effect. It's also possible that my printer's head is just plain shot (there's already a bad row of pixels..), and that everything is actually fine.

FS#588: Registration/Alignment issue with Black plane http://bugs.shaftnet.org/index.php?do=details&task_id=588 2017-11-28T03:03:38Z Solomon Peachy K extraction appears to work well, but when printing there's a registration problem.  The black layer appears to print several pixels higher than the color layers. I'm not sure if this is something that needs a fixed offset applied, or is something that can vary printer-printer.
