Driver for Laser Printer 1710n for MacOS Catalina

Hello, I am running MacOS Catalina 10.15.7. and have downloaded the Driver '1710 Mac Driver' with Drivers for Classic, 10.2., 10.3 and 10.4. from

DELL Site for Printer

https://www.dell.com/support/product-details/de-de/product/dell-1710n/drivers

DELL Download Link for Zip-packed Driver

My MacOS tells me that the file is corrupt. I tried all 4 versions.

Thank you for any help.

Kind Regards,
Tobias
