cups, filter failed

[Hopestation]

Hi.
I have been using a Dell 1320CN laser printer on a network for a long time with previous versions of Mint but now that I have installed Mint 20 Cinnamon I can't get the printer working.

I have copied the files that I used previously into /usr/lib/cups/ and checked that they are all owned by root and have "Allow executing file as program" set.

When I try to print a test page I get the message that the printer stopped with the message: "processing since Sun 27 Sep 2020 15:48:09 BST "Filter Failed".

I've looked in the error_log file and found the following lines:

I've compared the settings for the files in PID 2905, 2906, 2907 and 2909 with 2908 and I can't see any differences.

These show that PID 2908 failed stopped due to No such file or directory, but as I said at the start, this file exists with the correct permissions.

I've seen that there have been similar problems with the changes from Mint 18 to 19. Is this a repeat of the same problem?

No such file or directory often means that the filter cannot find something it is looking for, not that the filter itself does not exist. A link to the package it is in would be useful.

Hi Brian. Thanks for your reply.
I've finally had time to get back to the problem. Here is what's in the folder:

I've copied all the files in the Fuji_Xerox-DocuPrint_C525_A_AP-1.0-1.386.rpm file to the appropriate folders in File System.
I've tried to Make the Makefile in fxprefilter-1.0.0.tar.gz and it fails because it cannot find "makedefs", so I don't know if the prefilter is relevant.

I have used the .rpm files to get the printer working on 2 laptops, one running mint 8, many years ago and another that I now use, running Mint 18.
Before I upgraded my desktop from Mint 19.1 to Mint 20, that also worked, so I'm inclined to think that it is not the .rpm files that are at fault, but the change to Mint 20.
I tried inspecting the file FXM_PF in a HEX editor and there is some recognisable text but it didn't make any sense to me.
Any other suggestions would be welcome.
