You have to download and install the plugin. It is not in the hplip
package. Did you?

Are you talking about the plugin for the printer model?
A long time ago when I installed hplip for the first time it downloaded 
and installed something.
I forgot how I did that but the printer was working fine until I did the 
dist-upgrade.

I'm having a hard time seeing where the bug in hplip is.
My guess is that the update creates that /var/lib/hp/hplip.state file 
before installing the software and because of that it contains the old 
version number.


I only changed the version number in this file and everything started 
working again.

You have put your mail in an inappropriate place. Firstly, this is a
Debian bug report about the OfficeJet Pro 8710. Secondly, Mint will have
its own support channels. Thirdly, it helps neither you nor us.

As a Debian user you would have been advised to read the scanner section
of the Debian wiki and to have made sure you had installed the non-free
plugin from HP with the hp-plugin utility.

Bug#879719: NO SCANNER ON HP MFP Laserjet 477 fdn

2017-10-27 Thread Joeinslw 
I have discovered that when I was using Linux Mint 17.3 this MFP Laserjet
477 fdn worked fine both for printing and scanning, but now that I have
upgraded to Linux Mint 18.2 the printer works but there is no driver that I
can find for the scanner.  So scanning is a problem on 18.2, the message I
get is SCANNER NOT FOUND, I think it needs a driver, but no drivers are
available for 18.2.
I can not scan from the computer, so the only work around I have found is
to scan to a flash drive, then plug into computer and take the scanning
documents from there, a lot of work because there isn't a driver available
for 18.2

Package: cups
Version: 2.2.4-1
Severity: important

Hello,

Since the upgrade to 2.2.4-1 (more precisely, it is the upgrade of
libcups2 which breaks things), I'm not able to print any more:

[with 2.2.3-2]
$ lpq
print2me is ready
no entries

[with 2.2.4-1]
$ lpq
lpq: Error - PRINTER environment variable names non-existent destination 
"print2me".
$ lpr
/usr/bin/lpr: Error - scheduler not responding.
$ lp
lp: Error - scheduler not responding.

but oddly enough:
$ lpstat -a
print2me accepting requests since mar. 29 août 2017 14:13:48 CEST


Anyway, I had to downgrade to 2.2.3-2 to get printing back working.


I'm using
$CUPS_SERVER=cups.bordeaux.inria.fr
$CUPS_USER=thibault
$PRINTER=print2me

The server shows: CUPS 1.6.3

Description: File d'attente Follow Me
   Location: Follow Me BSO
 Driver: TOSHIBA ColorMFP (color, 2-sided printing)
 Connection: lpd://193.50.111.138/secure
   Defaults: job-sheets=none, none media=na_letter_8.5x11in 
sides=two-sided-long-edge


I have attached the TCP sessions of each version. It seems like the cups
client does not send $PRINTER to the server at all, thus "No default
printer" beign returned.

Packaging the new OpenPrinting project Common Print Dialog Backends

2017-10-27 Thread Till Kamppeter 

Hi,

as you perhaps know we have started a new project in this year's Google 
Summer of Code. Five students have worked on a new concept to assure 
feature completeness, printing technology support, and maintainability 
of print dialogs.


A problem of desktop printing is that there are many different print 
dialogs, from different GUI toolkits like GTK and Qt but also from 
individual applications like LibreOffice or the Chromium Browser. Adding 
new print technologies (like Google Cloud Print) or new features to 
existing print technologies (like CUPS' new feature of auto-creating 
temporary queues for driverless IPP printers) always require changes on 
the print dialogs and due to the fact that they are often not well 
maintained and that the GUI toolkits have rather long release cycles the 
new technologies and features do not get supported by the print dialogs 
of desktop apps.


To overcome this we have introduced a concept of separating the print 
dialog's GUIs from the print dialog's communication with the printing 
systems using a frontend/backend concept with a D-Bus interface.


For each print technology (currently CUPS/IPP and Google Cloud Print, 
soon also save to PDF file) there is a GUI-toolkit-independent backend 
doing the communication with the printing system and providing a D-Bus 
API to the frontends (the print dialogs). A print dialog, when it is 
opened, first does a broadcast call into the D-Bus to find which 
backends are installed, then calls the list-printers function of each 
backend to get a list of all available printers. When the user selects a 
printer, the appropriate backend is asked for further capabilities of 
the printer (to build the printer options screen) and if the "Print" 
buttonis clicked, the PDF is sent to the selected printer via its backend.


To get it into Debian (and from there into Ubuntu) at first the 
GUI-toolkit independent parts needs to get packages. These are the 
following projects on the new OpenPrinting GitHub 
(https://github.com/OpenPrinting):



cpdb-libs:

https://github.com/OpenPrinting/cpdb-libs

Frontend and Backend Libraries

These libraries allow for easy use of the D-Bus interface by print 
dialogs (frontends) and backends providing simple APIs so that the 
developer does not need to do the D-Bus communication directly.



cpdb-backend-cups:

https://github.com/OpenPrinting/cpdb-backend-cups

CUPS/IPP Backend

This backend does all the communication with CUPS (and IPP printers) for 
listing printers and capabilities and sending off print jobs. Needs 
cpdb-libs.



cpdb-backend-gcp:

https://github.com/OpenPrinting/cpdb-backend-gcp

Google Cloud Print Backend

This backend does all the communication with Google's servers for Cloud 
Print for listing printers and capabilities and sending off print jobs. 
Needs cpdb-libs.



These three projects need to be Debian-packaged in three source packages 
so that the GUI toolkits (GTK and Qt) and LibreOffice can get built with 
this functionality. LibreOffice has already adopted these changes to be 
included in their next release. GTK will have it in its next major 
release. Qt will probable include it in 5.10. An adaptor backend for 
using the Common Print Dialog Backends with current GTK's print dialog 
is in the works.


My plans are to introduce this new concept in Ubuntu 18.04 (Feature 
Freeze mid-February 2018). It would be great if the Debian packaging 
could be done soon so that I can sync it into Ubuntu.


Thank you very much for any form of cooperation.

   Till

You have to download and install the plugin. It is not in the hplip
package. Did you?

I'm having a hard time seeing where the bug in hplip is.

Bug#879950: Acknowledgement (hplip: lf317.1+rpak.1rPlugin mismatch after upgrade to 3.17.10+repack0-1)

2017-10-27 Thread Martin Furter 
I read the output of hp-check again and saw that it mentioned the file 
"/var/lib/hp/hplip.state" containing:

version = 3.17.6

The release notes of hplip 1.17.10 mention that this state file is new. 
So I thought if it is created by the new package then the old version 
does not make sense in that file. Then I edited the file and changed the 
version to 1.17.10 and now printing and scanning works fine.

Which is why there isn't any PPD in /etc/cups/ppd. I haven't looked

For stretch: cupsfilter: Unable to determine MIME type of "/etc/nsswitch".

There is something wrong with your CUPS installation (or the file
itself). I've never seen this in normal operation. It indicates that
a simple text file will not be printed. Try to rectify this with

 apt-get --reinstall install cups-daemon
 apt-get --reinstall install cups-core-drivers

to install the package versions of mime.types and mime.convs in
/usr/share/cups/mime.

You could have used CP310_dw.ppd; the PPDs on stretch and unstable are
identical.

Remove the .deb you downloaded from fujixerox and install the package
printer-driver-fujixerox from the Debian archives. It also comes from
fujixerox but it puts files in the right places on the system. Set up
the printer as before. This works for me to get a printable version
of nsswitch.
