Connection to printer failed

Hi,

You are required to install the updated version of HPLIP-3.16.9.

Download and install the latest HPLIP from
http://hplipopensource.com/hplip-web/install/install/index.html

install the run file using the following command.
sh hplip-3.16.9.run.

Then run the setup command : hp-setup IP

Thanks,
Kritika

No joy, still the same. Below is what I get with hp-testpage.

error: Unable to communicate with device (code=12): hp:/net/HP_LaserJet_Pro_MFP_M127fn?ip=192.168.2.10
error: Unable to print to printer. Please check device and try again.
error: Unable to communicate with printer HP_LaserJet_Pro_MFP_M127fn. Please check the printer and try again.

And this is with hp-scan.

Using device hpaio:/net/HP_LaserJet_Pro_MFP_M127fn?ip=192.168.2.10
Opening connection to device...
error: SANE: Error during device I/O (code=9)

I guess I shall open a bug? It's a shame every time I need to print or scan I need to start Windows in virtual machine, with printer/scanner allegedly fully supporting Linux.

Hi,

Can you please generate the logs for scan and attached them here using following command.

Run this command in first terminal
tail -f /var/log/syslog 2>&1 | tee ~/error_log.txt

In another terminal run command for scan hp-scan -g

After scan is complete, press CTRL+C in first terminal. You will find the log in /home/username/error_log.txt

Please attach the same logs

Hi,

It seems to be net snmp error. Can you please post the complete output of hp-check -t so that we can confirm net-smp is properly installed.

Also I am attaching the patch file for this code with more debug so that we can get to the bottom of the problem.

You can apply the patch by using following commands
"patch /path-to-hplip-source/io/hpmud/pml.c pml.patch"
After succesfully applying patch compile the code manually by using commands
make
sudo make install

After succesful installation Run this command in first terminal
tail -f /var/log/syslog 2>&1 | tee ~/error_log.txt

In another terminal run command for scan hp-scan -g

After scan is complete, press CTRL+C in first terminal. You will find the log in /home/username/error_log.txt

Please attach the same logs

Hope it will not be a problem. Thanks for your patience.
In case of problem please

Ajay

Hi Saul,

It appears with Linix hplip enabling SNMP in printer setup is mandatory.
