I have just updated my Ubuntu and set my printer back to factory settings, after which I reinstalled my printer (same way as before) but this time I'm getting a "Device Communication error (5012)".

I googled and found this solution and several referrals to it. The issue they mention seems to be exactly mine, only the way the solution is solved gives me questions.

Neither in hp-toolbox nor hp-setup do I find a field in which I can modify the

hp:/usb/HP_Color_LaserJet_MFP_M477fdw?serial=XXXXXXXXX

or

hpfax:/usb/HP_Color_LaserJet_MFP_M477fdw?serial=XXXXXXXXX

and change the serial=XXXXXXXX to ip=192.168.0.xxx.

Does anyone have any ideas about this? Maybe I can manually edit a file? Or, in the hp-setup I did see the fields network identification/hostname, but I didn't want to mess with this as I'm not sure, as it also wouldn't change the serial= to ip=, just the name to the number.

I just realised that when i plug in my usb cable the fax and printer under hp toolbox seem to be oke. the issue under hp-check still remains though but no Device Communication error (5012).

so to me it seems like the printer is not installed as wifi but as usb, maybe it is just that that is being fixed by changing the "serial=XXXXXXXX" to "ip=192.168.0.xxx",i'm really not sure.

summary of output:

sorry i couldn't get the bold in the code to work?

Oke..solved!!
this is what did i to, a lot of steps so i'm just gonna say step by step:

1) installed fresh install from ubuntu 17.10:

# sudo do-release-upgrade -d

2) removed all references (so far i knew to find them) from /etc/cups
basically sudo-ed and cleaned the entire folder out.

3) auto-removed hplip-gui

# sudo apt-get remove --auto-remove hplip-gui

4) somewhere here i was asked to partially updated ubuntu, which afterwards showed that it became a development version of 18.04
unfortunately i'm not sure if that was induced or just happened, and also don't know it that matters or how to find out.

5) auto-removed hplip

# sudo apt-get remove --auto-remove hplip

6) downloaded hplip-3.17.11 from hp site

7) installed hplip-3.17.11 following the installation notes from hp side

8) payed special attention to the installation notes at the beginning of the install.. and did them as such.

8a) software and updates: made sure it was on main-server

8b) locked the cd-rom by:

# eject -i 1

9) installed hplip-3.17.11

# cd desktop

# sh hplip-3.17.11.run

no dependency problems at all!

10) installed printer during install via gui

so printer seems to be properly set-up,

no communication error 5012,

via wifi

just still not found by xsane.

update:

i do get a

- unsupported platform warning when running hp-doctor

and

- a HPLIP error: Unable to communicate with device (code=12)

For the record: The problem is present in 18.04 with hplip 3.17.10 .

'hp-check -i' reports

warning: 12-18.04 version is not supported. Using 12-17.04 versions dependencies to verify and install...

warning: HPLIP-Installation: Auto installation is not supported for 12 distro 18.04 version

My Ubuntu 18.04 LTS suddenly got the same error message. Before, the printer worked just fine for some weeks. I solved my problem by observing that the printer, an HP Color Laserjet Pro MFP M280 nw, connected over the LAN, appeared twice in the Ubuntu printer dialog:

• HP ... M278-M281


• HP ... M280nw_ ...

The error appeared on the first entry; the second works just fine.
