Problem Sending Document to Printer

Hi - I need some assistance with my systems not printing or scanning over WIFI.
The printer/scanner is a HP_LaserJet_100_colorMFP_M175nw
When I try to print I get:

There was a problem sending document 'document name' to the printer.

Cups is running as I can print a pdf to a file and I can see my printer at:

localhost:631/printers/

I have stopped and started cups mulitple times:

systemctl stop cups.service
systemctl disable cups.service
systemctl enable cups.service
systemctl start cups.serive

I've re-installed Cups a few times.  I've also downgraded Cups, but that didn't help either.
I'm guessing whatever the issue is, it occured 3 - 4 weeks ago as I don't print or scan that often.
I have 2 systems running Arch and both can no longer print via WIFI
I can print from my cell phone, so I know the printer works.
In

/var/log/cups/error_log

it seems to indicate a broken pipe:

Not sure if that's a real issue or not.

Any thoughts would be appreciated.

Re: Problem Sending Document to Printer

D [11/Jan/2021:16:20:51 -0500] [Client 241] HTTP_STATE_WAITING Closing for error 32 (Broken pipe)

is from the cups http interface (localhost:631)

Can you ping/nmap the printer IP?
Do you use hplip (and forgot to update hplip-plugin)?

Re: Problem Sending Document to Printer

Yes, I can successfully ping my printer's IP.
I installed the updated hplip and hplip-plugin.  This allows me to print, but not scan.
So I ran

$hp-check

Which returned an error that I needed Python3 PyQt4.  So I installed that.
Now I get

$hp-check
Traceback (most recent call last):
  File "/usr/bin/hp-check", line 862, in <module>
    num_errors, num_warns = dep.validate(time_flag, is_quiet_mode)
  File "/usr/bin/hp-check", line 367, in validate
    self.__update_deps_info(supported_distro_vrs, dep,
  File "/usr/bin/hp-check", line 210, in __update_deps_info
    installed_ver = self.core.version_func[deps_info[6]]()
  File "/usr/share/hplip/installer/dcheck.py", line 303, in get_pyQt4_version
    from PyQt4 import QtCore
ModuleNotFoundError: No module named 'PyQt4.sip'

However I do have this directory

/usr/share/sip/PyQt4/

I tried to run

$hp-setup
error: No devices found on bus: net
error:  HPLIP cannot detect printers in your network.  This may be due to existing firewall settings blocking the required ports.
                When you are in a trusted network environment, you may open the ports for network services like mdns and slp in the firewall. For detailed steps follow the link.
                 http://hplipopensource.com/node/374 

Not sure where to go from here

Re: Problem Sending Document to Printer

https://wiki.archlinux.org/index.php/SA … roblems#HP
Also check https://wiki.archlinux.org/index.php/SANE

I don't have a HP scanner, so I also have no experience w/ hplip scanning.

Re: Problem Sending Document to Printer

Wondering if I could have a python problem...
When hplip tries to get the PyQt4 version it reports no PyQt4.sip

 $hp-check
Traceback (most recent call last):
  File "/usr/bin/hp-check", line 862, in <module>
    num_errors, num_warns = dep.validate(time_flag, is_quiet_mode)
  File "/usr/bin/hp-check", line 367, in validate
    self.__update_deps_info(supported_distro_vrs, dep,
  File "/usr/bin/hp-check", line 210, in __update_deps_info
    installed_ver = self.core.version_func[deps_info[6]]()
  File "/usr/share/hplip/installer/dcheck.py", line 303, in get_pyQt4_version
    from PyQt4 import QtCore
ModuleNotFoundError: No module named 'PyQt4.sip'

When I ask python the version, it can only report for PyQt5

$ python
Python 3.9.1 (default, Dec 13 2020, 11:55:53) 
[GCC 10.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from PyQt4.QtCore import QT_VERSION_STR
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'PyQt4.sip'
>>> from PyQt5.QtCore import QT_VERSION_STR
>>> print("Qt version:", QT_VERSION_STR)
Qt version: 5.15.2
>>> from sip import SIP_VERSION_STR
>>> print("SIP version:", SIP_VERSION_STR)
SIP version: 5.4.0
>>> 

Could PyQt5 have deleted the PyQt4 sip?  How would I go about getting PyQt4 back without dropping PyQt5?

Re: Problem Sending Document to Printer

PyQt4 is unnecessary, hplip from the arch repositories should use PyQt5 instead. (The ui-toolkit in /etc/hp/hplip.conf should be qt5)

Yes, the hplip.conf is qt5

and I'm running hplip 3.20.11-2 from the arch repos.

But inside usr/share/hplip/installer/dcheck.py there's this:

def get_python_dbus_ver():
    try:
        import dbus
        dbus_version ="-"
        try:
            dbus_version = dbus.__version__
        except AttributeError:
            try:
                dbus_version = '.'.join([str(x) for x in dbus.version])
            except AttributeError:
                dbus_version = '-'
    except ImportError:
        dbus_version = '-'
    return dbus_version

def get_pyQt4_version():
    log.debug("Checking PyQt 4.x version...")
    ver ='-'
    # PyQt 4
    try:
        import PyQt4
    except ImportError:
        ver='-'
    else:
        from PyQt4 import QtCore
        ver = QtCore.PYQT_VERSION_STR
    return ver


def get_pyQt5_version():
    log.debug("Checking PyQt 5.x version...")
    ver ='-'
    # PyQt 5
    try:
        import PyQt5
    except ImportError:
        ver='-'
    else:
        from PyQt5 import QtCore
        ver = QtCore.PYQT_VERSION_STR
    return ver

This is where it blows up

Re: Problem Sending Document to Printer

That looks like a broken PyQt4 installation is found by the hp drivers. Maybe remove it completely.

Re: Problem Sending Document to Printer

OK, I commented all calls for PyQt4 in

/usr/share/hplip/installer/dcheck.py
/usr/share/hplip/installer/core_install.py

now hp-check and hp-setup run.
However, hp-setup cannot find my network printer/scanner.
Nor can SimpleScan or Xsane.
But, system-config-printer can setup and print to the printer wirelessly.
Again, wireless printing and scanning has been working for 2+ years.

and, of course, it lets me know the printer is not hp installed

warning: Printer is not HPLIP installed. Printers must use the hp: or hpfax: CUPS backend for HP-Devices.

because under hp-setup -i <ip_address> it can't find my printer

Using connection type: net

error: No device selected/specified or that supports this functionality.

I've reinstall hplip and associated programs multiple times, read dozens of forums and hundreds of posts.
So far, it seems the common thread is:

  1. Problem occurs after a distribution upgrade

  2. Only resolution found by some folks on other dist. is a complete re-install. Which is here, quite undesirable.

To top it off, this issue is on two different machines that have been wireless printing and scanning for 2+ years

Thoughts anyone??

Re: Problem Sending Document to Printer

However, hp-setup cannot find my network printer/scanner.
Nor can SimpleScan or Xsane.

Did you try to access the scanner by IP (hp-makeuri)

Yes, but device not found

$ hp-makeuri <ip_address>

I even booted from an LTS kernel to make sure it wasn't something there, but no joy.

Re: Problem Sending Document to Printer

Not sure if this means anything, but hp-setup uses a python script to look for installed devices.

/usr/share/hplip/probe.py

I stepped through in debug mode and hit this

[DEBUG ON]

Any python gurus out there know if this is a real problem, or just a red herring?

Re: Problem Sending Document to Printer

I'm not sure which script you are referring to as python2?  I only know very, very little about python.  I did read the wiki post and I get python2 is no longer supported, and can maybe tick it into running.  I'm just running what the hplip has in it's directory.

Is there some action I can/should take?

Re: Problem Sending Document to Printer

/usr/share/hplip/probe.py

The error looks like something you'd get if you ran a python 2 script with the python 3 interpreter.
Ensure to have python2 installed, alter the shebang of the script and see whether it now runs correctly.

This might still be a red herring if hp-setup explicitly uses python2 anyway.
