Most new printers have PostScript built-in although if you are trying to print to an older printer or you are in a workplace with lots of PCs they may not have built-in postscript. If this is the case the default drivers in OSX will not work.
Here’s how I got my a non Postscript Fuji Xerox printer working with my 2020 MacBook Pro running Catalina.
- Give the printer an IP address. (e.g. 10.0.0.200)
- Download the latest drivers manually from Fuji Xerox. (https://onlinesupport.fujixerox.com/processDriverForm.do?ctry_code=SG&lang_code=en&d_lang=en&corp_pid=DCVC2263&rts=null&model=DocuCentre-V+C2263&type_id=2&oslist=Mac+OS+X+10.15&lang_list=en)
- In System Preferences: Printers go to Add new printer, select IP then put in the options as follows:
I needed to select LPD because IPP didn’t work.
I needed to select FX Print Driver for Mac OSX. The default DocuCentre drivers (Called FX DocuCentre-II C4300 v3016.103 PS) did not work. The specific drivers for a printer rely on the printer having Postscript, whereas the FX generic print driver does not need the printer to have Postscript installed.
