Mistake in models.dat for Color Laserjet M280

[Steffen L]

When scanning for a Color Laserjet M280 with hp-setup on the network it is not being found, even when specifiying the ip address. Running hp-setup in debug mode shows that the printer is reporting itself as "hp_colorlaserjet_mfp_m278-m281", but the section in models.dat reads "hp_color_laserjet_mfp_m278-m281" (note the extra _). Therefore the printer is not found at all and can not be used.

hplip version: 3.19.10
Distribution: Linux Mint 19.2
Printer firmware date: 20190716

Editing the section name in models.dat fixes the problem and the printer can be installed. This is the output of hp-check after manually editing models.dat:

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies are installed to
successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has the proper dependencies
installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time dependencies).

Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]

[shivani mandora (shivani1708)]

Hi,

Thanks for pointing out the issue. We will fix it and let you know the progress.

Thanks,
Shivani

[brian_p (claremont102)]

Shivani, I hope mentioning https://bugs.launchpad.net/hplip/+bug/1822762 is not out of place in this report. #1822762 is not yet fixed. Messages #7 and #8 could also be looked at for similar bugs.

[jan.public (jan.public-redhat-bugs)]

I have problems again with accessing my HP M281fdw LaserJet printer. It started with the fact that scanning did not work any more.

See bug 1694663 for details on problems that I had before.

In an attempt to get my LaserJet scanning again, I installed hp-plugin. The scanner did still not work. Next, I removed
/usr/share/hplip/data/models/models.dat
because I did this in the past once as well, and reinstalled hplip:
# dnf reinstall hplip*

Next I removed the two entries of the LaserJet in Gnome-Settings|Printers (the avahi discovered one and the previously manually added one).

Then I tried to reinstall the LaserJet from Gnome-Settings|Printers. But this results now in a Failed to add new printer popup window.

Here is an excerpt from my journal:

[jan.public (jan.public-redhat-bugs)]

Maybe this bug is a duplicate of: https://bugs.launchpad.net/hplip/+bug/1851013
I will try to test if that is really the case, and report the results here.

[jan.public (jan.public-redhat-bugs)]

OK, I did the test. Indeed this bug is similar as bug https://bugs.launchpad.net/hplip/+bug/1851013
I edited a line in /usr/share/hplip/data/models/models.dat as suggested.
Note that I have now this info in the file mentioned above:

[hp_colorlaserjet_mfp_m278-m281]
...
ppd-name=hp-color_laserjet_mfp_m278-m281-ps.ppd
...

Note the inconsistent use of the _ in color_laserjet and colorlaserjet

After editing the line I ran hp-setup and the printer was detected. After this, scanning via SimpleScan works as expected.

I leave it up to you to leave this bug open or to close it as duplicate of an external bug.

[Jan Vlug (jan-vlug)]

I would kindly ask to take comment #2 into account.

I went through a lot of trouble with my HP Color LaserJet Pro MFP M281fdw that I especially selected because the official HP website states that no plugin is required.

[zdohnal (zdohnal-redhat-bugs)]

Hi Jan,

thank you for reporting the issue and I'm sorry for regression :(

3.19.10-2+ should now have again colorlaserjetxxx entry for m278-m281 (HP should really have a standard how their printers should report themselves...)
