Flyspray:: Thu, 22 Feb 2018 19:40:13 +0000 Flyspray::CUPS Dyesub Backends: Recently opened tasks http://bugs.shaftnet.org/ 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.

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#595: When trying to enumerate printers, don't block for a long time when one's busy Solomon Peachy Fri, 16 Feb 2018 12:11:44 +0000 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.

Not sure if it uses sheet or roll media.

FS#591: Investigate Kodak DL2100 Solomon Peachy Fri, 26 Jan 2018 01:51:20 +0000 It's a duplexing "electro-photographic" (AKA laser) printer @600x1200dpi.  They rarget photo books and calendars with it.

 

Appears to be a rebranded version of the Oki C712.

FS#589: Fix 8bpp->6bpp color scaling Solomon Peachy Tue, 28 Nov 2017 03:07:05 +0000 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 Solomon Peachy Tue, 28 Nov 2017 03:03:38 +0000 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.

FS#586: Add JSON output Solomon Peachy Fri, 24 Nov 2017 01:03:31 +0000 This might not be feasible in a general sense due to the need to interact with CUPS.  But it's worth investigating.
