Bug 1544912

Hi,

to sum it up previous comment - gnome control center creates different (not working) scanner uri for network scanner than 'hp-setup' command from hplip package (which works). Would you mind giving a more insight into how scanner uris are created in control center? I think control center just calls a function from libsane to get scanner uris, but I'm not sure (that means I do not know if it is issue for control center or sane).
Thank you in advance.

Yes gnome-software fails to list anything. It just says that the missing software could not be found. Pointing to hplip or if possible the plugin directly would be sensible.
The plugin is installed but gnome-settings is not able to use it.

Changing the name - I misunderstood you, I thought you have problem with scanner uri.

The Scanner is not working over network via gnome-settings AND the printer is PCL3 only and prints garbage. This is happening with the propietary hp plugin installed. 

Via PCL3 it just prints one random line per page instead of the desired output.

Via hp-setup scanning and printing works.

What do you mean by proprietary plugin installed? Did you run 'hp-plugin -i' after gnome installation?

I have installled the Plugin via the hplip GUI and hp-plugin -i says that it is already installed. It works fine. The printer is properly installed via hp-setup. If i try to add it again via gnome-settings it only adds a pcl3 garbage printer and no scanner

Device needs proprietary plugin, which cannot be in Fedora, that's why gnome-settings installed as generic pcl3 printer. Closing as NOTABUG.

Installation process with gnome-settings

Yes but if the plugin is installed why does gnome not use it? The plugin should be necessary for scanning only. The printer supports ipp and other protocols which should allow network printing. 

It is not listed on https://developers.hp.com/hp-linux-imaging-and-printing/binary_plugin.html that it needs a plugin for printing.

I was able to get it to print properly by installing it as jetdirect printer instead of PCL3 and then sellecting the 277 modell. The steps can bee seen in the attachment. LPD might also work.

Why is it insatalled as PCL3 which does print garbage only and not jetdirect?

Plugin is needed for both - printing and scanning.

If you look into 

https://developers.hp.com/hp-linux-imaging-and-printing/supported_devices/index

your printer isn't listed there neither. Hplip was patched to work with your printer in our OS and uses proprietary plugin for m277 series (see /usr/share/hplip/data/models/models.dat).

Control center doesn't create correct uri, because your printer doesn't have his own plugin.

I can try to copy m277 plugin and name it accordingly - I can make scratch build to test.

Please try these rpms - now control center should install correct uri https://koji.fedoraproject.org/koji/taskinfo?taskID=25216764

I have installed 

libsane-hpaio-3.17.11-10.fc27.x86_64.rpm
hplip-libs-3.17.11-10.fc27.x86_64.rpm
hplip-gui-3.17.11-10.fc27.x86_64.rpm
hplip-common-3.17.11-10.fc27.x86_64.rpm
hplip-3.17.11-10.fc27.x86_64.rpm

and rebooted.

It did not change anything. I can provide more debuginfo if you tell me how to do so.

Julius,

can you please check if 'rpm -q --provides hplip | grep m278' returns anything? It should return one postscriptdriver tag for m278-m281. Then we can check what model name your printer has by '$ lpinfo -l -v' (would you mind running it twice - one for hp created printer, other for control-center created printer?)

[julius@julius ~]$ rpm -q --provides hplip | grep m278
postscriptdriver(hewlett-packard;hp_colorlaserjet_mfp_m278-m281;)

Network COnfiguration

I have installed fedora 28 final release candidate and at first it was worse than in Fedora 27. There is no m281 ppd file anymore and it was recognized as m176n without duplex by hp-setup. Then i found the following solution. In the printer web frontend you can disable everything not needed as seen in the attachment. Then it is always recognized as postscript and works nicely. 

Nevertheless the scanner does not work. But on https://forums.fedoraforum.org/showthread.php?317915-Print-amp-scan-with-an-HP-Color-LaserJet-MFP-M281-(fdw)&p=1806395 is a solution.

i have created the file /usr/share/hplip/data/models/unreleased/unreleased.dat containing

This allowed me to scan without adding any printers. It would be very kind if someone could merge those changes into fedora 28.

There wasn't such ppd file before at all. I only created m281 ppd file for testing purpose in our previous conversation. It used m277 ppd file.

Similar should be in /usr/share/hplip/data/models/models.dat, can you check if it is there? Only the first line is changed - if I changed it in this build https://koji.fedoraproject.org/koji/taskinfo?taskID=26539313 , does it work correctly?
I would like to remind that printer isn't supported in hplip, so such problems are understandable.

I removed /usr/share/hplip/data/models/unreleased/unreleased.dat, removed all of hplip, except for the plugin and installed the files you provided on fedora 28. I rebooted and it works. The workaround also works on clean fedora 27 with hp-plugin, while the files you provided do not install on fedora 27 for dependency reasons. Sadly, you still need the binary soap scan plugin from hp-plugin for scanning until someone implements ws-scan or airprint scan in sane.

I strongly suggest moving this to updates-testing

Glad to hear it - I'll issue a build.

hplip-3.18.4-1.fc28 has been pushed to the Fedora 28 stable repository. If problems still persist, please make note of it in this bug report.

I just upgraded multiple machines, some to F27, some to F28. Both show the same flaw: hp-setup fails to recognize the Printer.
I don't know, how Julius (in comment #16) got to his conclusion - maybe he only removed the files but did not attempt to run hp-setup again.

Anyway: The reason for the failure is simple:
There is a typo in models.dat. The necessary tag is "hp_colorlaserjet_mfp_m278-m281" (see also Julius' debug output in bug #1544788
https://bugzilla.redhat.com/attachment.cgi?id=1395564
)
but in models.dat it is named "colorlaserjet_mfp_m278-m281" (the prefix "hp_" is missing)

I think I don't need to attach a patch here as this change ist so trivial.

Cheers

Forgot to mention the package versions tested by me:

1. hplip-common-3.18.4-2.fc27.x86_64
2. hplip-common-3.18.4-2.fc28.x86_64

Thank you for finding it out, Fritz! I'll revert the updated patch after Julius' report.

HP seems to support m278-m281 model officially in hplip-3.18.5. I'll remove the patch completely, would you mind checking if installing your printer works with hplip-3.18.5? There will be an update in bodhi with 3.18.5 today.

With hplip 3.18.6 the scanner is not detected.

i need to call hp-makeuri 192.168.2.106
and then 
simple-scan hpaio:/net/HP_ColorLaserJet_MFP_M278-M281?ip=192.168.2.106 
to scan. The Sane URI is not automatically created and propagated.

Hi,

please file a new bug on sane-backends, which is primarily component for scanning issues, and attach there a file with logs gathered by this command (when you don't have scanner installed):

$ SANE_DEBUG_HPAIO=255 SANE_DEBUG_DLL=255 SANE_DEBUG_SANEI_TCP=255 scanimage -L &> sane.debug
