HPLIP

Dependency always missing: pyqt4-dbus and pyqt4? [hplip-3.20.5]

Asked by Lorenzo

Hello,

i've some problem when installing hplip-3.20.5.
In fact, the installer doesn't recognize these following dependencies (both if I choose to avoid installing the qt4 gui in custom mode and in automatic default mode):

- pyqt4-dbus
- pyqt4

I use debian as os. I've just installed these qt4 rquired package (that should be ok):

python-qt4 is already the newest version (4.12.1+dfsg-2+b1).
python-qt4-dbus is already the newest version (4.12.1+dfsg-2+b1).

And these qt5 rquired package (that should be ok):

python-pyqt5 is already the newest version (5.11.3+dfsg-1+b3).
gtk2-engines-pixbuf is already the newest version (2.24.32-3+rpt1).
python-dbus.mainloop.pyqt5 is already the newest version (5.11.3+dfsg-1+b3).

But the problem is not solved.

-> Where i'am wrong?
-> Why if I choose to avoid installing the qt4 gui in custom mode it keep asking me for the qt4 package?

******************************************************************************

In my opinion there is some bug in the installer because in the end it always asks for the dependencies of qt4 (when in relation it should be ask only that of qt5)..

Thanks to everyone.

Knowing the Debian version and the printer model would be useful.

The OS is Raspbian 4.19 (for RaspberryPi), practically the son of Debian Buster 10.4 .

The printer model that i have is: HP Color LaserJet MFP M283fdw .

PS: I already know that hp-lip 3.20.5 actually doesn't support it (it supports <= Debian 10.3).

But i know that someone has already successfully installed hp-lip on this OS.

PSS: For example, this https://packages.debian.org/sid/hplip is a hp-lip 3.20.5 working package from Debian unstable (sid) repo.

Hello Lorenzo,

I am not keen on debugging HPLIP, so I am going to assume your primary
objective is to print and scan. Please connect the M283fdw to the network
with wireless/ethernet and give what you get for

  driverless
  avahi-browse -rt _ipp._tcp
  avahi-browse -rt _uscan._tcp

Cheers,

Brian.

Hello Brian,

yes, my primary objective is to scan and after to print.

I should scan via wifi using "scanimage".

I know that one method (that works) to do that is using hp-lip (hpaio:/net/<aio_model_name>?ip=<IP_address_of_the_aio>).

I post here what you asked me:

Please give sane-airscan a try:

  https://github.com/alexpevzner/sane-airscan

Debian packages for buster are supplied and it has a 100% success rate
for users who have employed it.

> pi@raspberrypi:~ $ driverless
> ipp://NPI99B494.local:631/ipp/print

The output is a URI. Substitute for it in the following command:

 lpadmin -p PRINTER_NAME -v URI -E -m everywhere

PRINTER_NAME can be anything that suits you.

I would appreciate having the output of 'scanimage -L if you use sane-airscan.

Cheers,

Brian.

Apologies Lorenzo; I forgot - you are using a Pi. You will have to build
from source. I did the on i386 and it worked well. The author is very
approachable should you have problems.

Yeah, thank you very much man!
Within this weekend i will try to implement and test your valuable advice/alternative.
I will definitely update you on the result! :)

Hi everybody,

I have aarch64 packages for Debian 10.0

@brian_p:

Hello!

Sorry for the delay but I have been busy these days .. Anyway, this is the result of what you asked me:

pi@raspberrypi:~ $ scanimage -L
device `airscan:e0:HP Color LaserJet MFP M283fdw (99B494)' is a eSCL HP Color LaserJet MFP M283fdw (99B494) eSCL network scanner

This with sane-airscan compiled for RaspberryPi.

Also i managed, from the VirtualBox VM, to simulate RaspberryPi Desktop OS (Similar to Raspbian for ARM). I downloaded it and installed hplip 3.20.5 + dfsg0-3 (https://packages.debian.org/sid/hplip) from Debian Unstable (sid) repo.
And I noticed the following intresting differences between hplip and sane-airscan:

With sane-airscan backend:

standard output.

                           %m (model), %t (type), %i (index number), and

The differences are seen .. Unfortunately.

----------------

I noticed that on the virtual machine i use (that is RaspberryPi Desktop OS) the following three commands do not give (empty) results:

  driverless
  avahi-browse -rt _ipp._tcp
  avahi-browse -rt _uscan._tcp

Why, according to you?

PS: While i see my printer only with hplip and sane-airscan?

Thank you very much for all man! :)

@Alexander

I don't think that aarch64 packages for Debian works on RaspberryPi. I must only use armhf.deb packages..
