hp-toolbox works, I can read all printer status including ink levels.
hp-info, hp-levels, hp-probe works.

The only one thing is bad: I can not print. Every printing ends up in printer
queue. No difference is it text from text editor, cups test page or
hp-testpage output. Everything lies in queue and nothing happens.
Printing works in windows.

Downgrading to 2.7.6 makes no difference.

hp-check in 2.7.7 is broken when compared to hp-check 2.7.6 which works fine.

Where I should start looking for problems? What I should check?

I tested hplip 1.7.1 and 1.7.4a - prints. The printing problem exist with
2.7.6 and 2.7.7 only. It looks there is no hplip service to load - maybe this
is the reason? If hplip service changed its name what I should load instead?

hpiod (the I/O daemon in pre-2.7.6 releases) had been replaced by a shared
library hpmud. So, there is no service/daemon to startup or load.

If you are printing using USB, the most likely cause is a permissions
problem with the udev node for the printer. Have you gone through the steps
in the manual installation instructions?

OK. Works. Just installed missing required snmp and sane (reported by
hp-check), then as root set up new printer and printing works.
Then removed both snmp and sane. After reboot printing still works.
hp-check said my rights/configuration is OK - only snmp and sane was missing.

I thought snmp and sane were only required when network/scanning features are
needed. But it looks they are needed at ordinary printer setup phase too.

Now both hplip 2.7.6/2.7.7 printing works.
thanks for help,
Zbigniew
