Danke, alles schon gecheckt.
Mir widerstrebt es einen neuen Drucker zu kaufen, wenn der alte doch noch funktioniert.
Ich habe jetzt allerdings doch was gefunden und das schein mein Problem zu sein. Heißt ich brauche irgendwoher so einen DIMM
There are two issues. First is the issue of a parallel to usb adapter which you can get at the link below:

The second issue is postscript which is the language MAC's use. MAC sometimes provides drivers that will work on pcl printers but you need to check. There is also a postscript dimm which can be added to your printer to make it accept postscript. To see if you already have the dimm, just press both buttons at the same time on the printer when it is ready and it will print a configuration page which will tell you the languages contained in the printer. Below is a link for the postscript dimm.
