Dell Color Laser 1320c with Mac OS 10.15 Catalina: Filter failed
This fixes the &quot;Filter failed&quot; (German: &quot;Filter fehlgeschlagen&quot;) error with Dell Color Laser 1320c printers under Mac OS 10.15 Catalina by leveraging the Fuji Xerox C525A printer driver which is similar to the native Dell driver.

Finish the setup. In order to be able to print using the paper try, please apply the following setting: &quot;500 sheet feeder&quot;




When you print something for the first time, you'll need to set the correct paper source. -Click the &quot;Show Details&quot; button on the print dialog screen. -In the &quot;layout&quot; pulldown select &quot;Full Zerox Features&quot; --Select &quot;Paper source: Tray 1 (500 sheets)&quot; :



After that, you can save the current settings as a reusable preset. (You might need to Google how to do that). :)
