I am about to (finally) update my OS to Catalina and a search found that the software that came with my printer is not 64 bit compatible including the online user manual. There are new manuals on the Canon website but I cannot determine if they are 64 bit. Anyone else have this issue?</P> Fri, 29 Jan 2021 20:07:50 GMT https://community.usa.canon.com/t5/Professional-Photo-Printers/64-bit-compatibility/m-p/332901#M11012 Pytrouble 2021-01-29T20:07:50Z https://community.usa.canon.com/t5/Professional-Photo-Printers/64-bit-compatibility/m-p/332929#M11013 <P>Welcome to the forum.</P><P>&nbsp;</P><P>You will need to rely on this:</P><P>&nbsp;</P><P><A href="https://ij.manual.canon/ij/webmanual/Manual/M/PRO-100S%20series/EN/CNT/Top.html" target="_blank">Canon : PIXMA Manuals - PRO-100S series -</A>&nbsp; There may be one for the plain Pro-100 (no S) but I haven't found it.
