cups-insecure-filter error for Lexmark printer on Trusty

Question

I am trying to install my Lexmark S800 Series printer (32-bit) on Ubuntu 14.04 Trusty, and I continue to get a cups-insecure-filter error message. The printer is connected to LPT1, and the printer wizard correctly adds the Printer/PPD. It's when I first go to print a test page that I get the error.

I followed the instructions on this page to ensure that the permissions were correct for /usr/local/lexmark/v3/bin/printfilter.

Has anyone else had this issue trying to get a Lexmark printer running on Trusty? No amount of googling has helped on this one.

Thank you!!

Answer 1

This is probably too late to help the original poster, but for others searching some day:

sudo chmod g-w /usr/local/lexmark/v3/etc/lxS800.ppd
sudo /etc/init.d/cups restart

For other models of Lexmark printers, choose the appropriate .ppd file in /usr/local/lexmark/v3/etc

Answer 2

I have an Epson WF-3520 and was getting the cups-insecure-filter error.

I've solved it by setting the owner of the Epson source directory to root:

sudo chown root:root -R /opt/epson-inkjet-printer-201212w/

It's installed on /opt directory, which I've also changed to owner root. I don't know if this is relevant.

After that I was getting following error in the log /var/log/cups/error_log:

Job stopped due to filter errors; please consult the error_log file for details.

I solved it by recovering some permissions that I had previously changed on some tests:

sudo chmod 755 /opt/epson-inkjet-printer-201212w/cups/lib/filter/epson_inkjet_printer_filter 

Answer 3

I was getting this error with my Epson Workforce 840 on 16.04 because root was not the owner of /opt/epson-inkjet-printer-workforce-840-series.

This was fixed by changing the ownership to root with:

sudo chown -R root /opt/epson-inkjet-printer-workforce-840-series

followed by restarting cups with:

sudo /etc/init.d/cups restart

Finally, and this part may or may not have been necessary, I also deleted and re-added the printer.

Answer 4

In my case problem was with file /usr/local/lexmark/v3/bin/printfilter as in the original question, same solution above applied to this file solved the problem for me:

sudo chmod g-w /usr/local/lexmark/v3/bin/printfilter
sudo /etc/init.d/cups restart

This is rather simpler as the page linked in the original question. Thanks

Thanks to https://www.kubuntuforums.net/showthread.php?61633-Cups-insecure-filter-Lexmark-Prospect-Pro205-and-scanning-issues this worked for me:

sudo chmod 755 /usr/local/lexmark/v3/bin/*

sudo chown root:bin /usr/local/lexmark/v3/bin/*

Answer 6

This worked for me (ubuntu 16.04.1 - lexmark S405):

cd /usr/local/lexmark/v3/bin/
sudo chmod 755 printfilter

I take from this Ubuntu forum tread

Answer 7

I tried all of about file permissions on the internet. They couldn't solve the insecure permissions issue.

My original driver is located on /opt/brother/..... and there is a symbolic link on /usr/lib/cups/filter.. permission was

lrwxrwxrwx  1 root root     68 Eyl 28 05:37 brother_lpdwrapper_HL1210W

original file permissions was

-rwxr-xr-x 1 root root 5139 Eyl 16  2014 /opt/brother/Printers/HL1210W/cupswrapper/brother_lpdwrapper_HL1210W

I removed symbolic link and move file to /usr/lib/cups/filter/

and it solved my issue...
