Dell Color Laser 1320c with Mac OS 10.15 Catalina: Filter failed After upgrading to Mac OS 10.15 Catalina, trying to print with a Dell Color Laser 1320c leads to the error message: Filter failed (German: Filter fehlgeschlagen).
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.

Download the driver: http://onlinesupport.fujixerox.com/processDriverForm.do;jsessionid=EFF824E51694F73EAFA2D75F3E85546F.worker4?ctry_code=KR&amp;lang_code=en&amp;d_lang=en&amp;corp_pid=DPC525A&amp;rts=null&amp;model=DocuPrint+C525A&amp;type_id=2&amp;oslist=Mac+OS+X+10.13&amp;lang_list=en

Open the .dmg file, then open the .pkg file (via right click &gt; open)

Finish the setup guide

Click on the Apple Menu in the upper left-hand corner of your screen and select System Preferences... click on Printers &amp; Scanners.

Unlock the window using the lock icon in the lower left corner if necessary

Click on the + sign to add a printer

Change the 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). :)
