File "/opt/epson-inkjet-printer-escpr/cups/lib/filter/epson-escpr-wrapper" has insecure permissions (0100775/uid=1000/gid=1000).
sudo chmod 755 /opt/epson-inkjet-printer-escpr/cups/lib/filter/epson-escpr-wrapper
I have changed the chmod permissions to 777, even. I have deleted and reloaded the printer twice, rebooted twice but I still get this same message on the Printer Properties/Printer State line.
There is also a Status message on the Printer Properties->ink toner levels line in Printer Properties; "cups insecure filter", which I do not seem to be able to get rid of.
Something funny going on here ??
Any more ideas, please ?
sudo chown -R root /opt/epson-inkjet-printer-escpr/cups/lib/filter
sudo chgrp -R root /opt/epson-inkjet-printer-escpr/cups/lib/filter
sudo service cups restart
sudo dpkg -i <PACKAGE-NAME>
I have downloaded the drivers from the Epson website, as the System Settings → Printer dialogue does not offer drivers for this particular printer.
I then unzipped the driver package and also unzipped a package specific to the printer, Epson-wf-2520_Series-epson-inkjet-printer-escpr.ppd
Still no luck; the printer did not work and I got an error message to the effect that a file called 'epson-escpr-wrapper' could not be found.
I am no linux expert but I eventually located the file and moved it to opt->epson-inkjet-printer-escpr->cups->lib->filter
