As a test, I changed [hp_colorlaserjet_mfp_m278-m281] to [colorlaserjet_mfp_m278-m281] in /usr/share/hplip/data/models/models.dat Then I executed: [jan@nyx ~]$ scanimage -v -p -d hpaio:/net/hp_colorlaserjet_mfp_m278-m281?ip=192.168.178.16 > myscan scanimage: open of device hpaio:/net/hp_colorlaserjet_mfp_m278-m281?ip=192.168.178.16 failed: Operation not supported So not that the "Error during device I/O" changed to "Operation not supported".

Maybe this is of interest as well: I have been experimenting previously to fix this issue. I disabled AirPrint, and changed the AirPrint Bonjour service name in the webinterface of the printer. Unfortunately, I did not write down the original AirPrint Bonjour service name. Currentlly it is "ColorLaserJet MFP M278-M281" I guess that the original was "HP ColorLaserJet MFP M278-M281", but as said, I'm not sure about that. I think that I also experimented with replacing spaces by underscores.
Another remark: The webinterface of the LaserJet printer/scanner is quite confusing. There is a screen "AirPrint Status". In this screen, I disabled AirPrint. In the same screen there is also a "Bonjour Service Name:" field. This field can still be changed when AirPrint is disabled. And the value of this field is actually used for the service name in the mDNS advertisements even when AirPrint is disabled. It looks like that the Bonjour service name is not used for determining the model. This seems correct to me. These are the mDNS properties that I currently have: Service Type: _scanner._tcp Service Name: Jan HP ColorLaserJet MFP M278-M281 <= Note that I changed this one in the webinterface of the printer/scanner Domain Name: local Interface: enp30s0 IPv4 Address: NPIA997CD.local/192.168.178.16:8289 TXT flatbed = T TXT mdl = ColorLaserJet MFP M278-M281 TXT mfg = HP TXT usb_MFG = HP TXT button = T TXT ty = HP ColorLaserJet MFP M278-M281 TXT UUID = 564e424e-4c44-5744-4e58-e4e749a997cd TXT feeder = T TXT note = TXT adminurl = http://NPIA997CD.local.

Thank you for all the info! It really looks like issue #1797501 from launchpad... but there is other log about plugin, would you mind reinstalling it? About the string-cutting issue - would you mind removing models.dat, reinstalling hplip packages and setting your default printer settings? It would be better to have default settings than work on something obscure. I would try to use Brian's patch, just to cross it out. The patch should be in https://koji.fedoraproject.org/koji/taskinfo?taskID=33867700 , would you mind trying it out?

Then I opened GNOME Settings went to Printers and removed all ColorLaserJet entries. After a short while Jan_HP_ColorLaserJet_MFP_M278_M281 appeared automatically (screenshot_0.png). When I click on the gear icon | Print Options, I see a nearly blank window (screenshot_1.png). The Test Page button does not print a test page. The Printer Details window is shown in screenshot_2.png. Then I clicked the Add... button. Selected HP-ColorLaserJet-MFP-M278-M281 (screenshot_3.png), clicked the Add button. The Printers window looked like screenshot_4.png. I clicked the gear icon of the newly added HP-ColorLaserJet-MFP-M278-M281. The menu seems correct and contains: Printing Options, Printer Details, Use Printer by Default, Clean Print Heads, Remove Printer. Selecting Printing Options, and then clicking the Test Page button did not print a test page, but crashed GNOME Settings. I will try to report the crash via ABRT and put a link here. Question: how do I apply the patch? Can I download an rpm? I'm willing to test it.

There are links to rpms in the link I provided in my last commentary, just install them with dnf (dnf can take links as input too)
GNOME Settings crashed multiple times when trying to print a test page. ABRT has difficulties reporting most of the crashes, but one crash was reported as a duplicate of bug 1662583. I will test the patch. At the moment (i.e. without the patch) I cannot print a test page any more. When I click the Test Page button, the LCD in the printer states: Unable to print file. File is corrupt. Usually GNOME settings crashes soon after this.

First of all, the whole problem with printing a test page is probably completely a separate bug. I will create a bug for that later. I noticed that I can print from Libreoffice, but the printing a test page from GNOME Settings does not work.

I created bug 1694797 for the issue with printing a test page.

Please try to run 'hp-plugin -i' - it would not be the first time when hplip pages says one thing and sw does the other. And since they reply on the cases once a several months, it is difficult. If it would help with the issue, then it is worth to investigate more.
Plus, would you mind installing a printer with hp-setup -i <your_printer_ip> ?
First, I installed the plugin with $ hp-plugin -i After this, I could make a scan with: $ scanimage -v -p -d hpaio:/net/HP_ColorLaserJet_MFP_M278-M281?ip=192.168.178.16 > scanimage I verified that the scanimage had content. There was, very low resolution, no color. Next I ran $ hp-setup -i 192.168.178.16 After this, I could still make a scan with $ scanimage -v -p -d hpaio:/net/HP_ColorLaserJet_MFP_M278-M281?ip=192.168.178.16 > scanimage2 I noticed no differences. Though a new printer shows up in GNOME Settings Printers. For this new printer in GNOME Settings I clicked Test Page. Which correctly printed the test page (after I accepted via the printer touch LCD screen that it was ok to print a letter format to my loaded A4 paper. Next, I tried with the previously installed entry for the printer in GNOME Settings Printers to print a test page by clicking the Test Page button. This still resulted in "Unable to print file. File is corrupt" message on the printer LCD. The next thing that I intended to try was to test scanning with simplescan, but because both printer instances in GNOME Settings Printers (the old one and the one installed with hp-setup) have the same name, I could not select the printer. So I went back to GNOME Settings Printers to remove the old instance. But even before I got there GNOME Settings crashed again. Gnome Settings crashes very often, and usually there is not enough information for ABRT to create a Bugzilla issue. Now I first will try to report the crash. Later I will test scanning with simplescan or whatever you suggest. So there is progress, thanks for your work on this!
I created bug 1694979 for the crashes in GNOME Settings Printers (gnome-control-center).

Btw your device seems to have one of scanning handles which needs the plugin for scanning support (according the code - because loading functions for device handlers escl, marvell, orblite, soap and soapht calls load_plugin_library(), which checks the plugin...), so the record on website is wrong. I'll update the record in source tarball, but nothing I can do (then filing other report...) about upstream website.
Plugin issue is reported as https://bugs.launchpad.net/hplip/+bug/1822762 .
I added the patch for parsing issue and plugin. Now hp-setup will know your device needs plugin for scanning, so it will be prompted to install - however, gnome-control-center does not know anything about plugin, so scanning will not work with automatically created print queue. It is like that because of plugin's license, which is incompatible to Fedora, so it could not download automatically (only on user's request - with hp-setup or hp-plugin).
Hi Zdenek, I was able to scan now with simple-scan, using the new instance of the driver, also in high resolution. One thing that I note, is that the new printer representation (the one that appeared after running hp-setup) in GNOME Settings Printers does not visualize the ink levels. Should I create a separate bug for that? Or add this to bug 1694797? Another thing: the other scanner that I have in my network (HP OfficeJet 4650) is now not visible anymore in simple-scan.

IMO these ink levels can be negotiated only for dnssd/ipp backends (and if the printer can do it at the same time), so it is expected. > [jan@nyx ~]$ scanimage -L > device `hpaio:/net/HP_ColorLaserJet_MFP_M278-M281?ip=192.168.178.16' is a > Hewlett-Packard HP_ColorLaserJet_MFP_M278-M281 all-in-one > device > `hpaio:/net/colorlaserjet_mfp_m278-m281?ip=192.168.178.16&queue=false' is a > Hewlett-Packard colorlaserjet_mfp_m278-m281 all-in-one > > I installed this device again with: > hp-setup -i 192.168.178.12 General advice for HP scanners and MFD - try hp-setup - because hpaio backend (which is run when searching for scanners) needs exact uri as it goes from hp-setup for correct work.

(My guess it is a remnant of some previous gnome created print queue - because hplip does printer discovery and asking CUPS on its own and based on that tries to create scanner URI for devices which has support for it). > Regarding the plugin: I agree with you.
