I have an installation disk but my PC has no DVD slot any more. So got some 'ddst' driver for 64 bit. This is some kind of archive. In WIN 10 the file names change but I could fix that. Tried to install the driver via .exe = no way. Then add printer manually, 'have disk' and then browse to .inf file (which I hope was the correct one/). It tells at the end that this might not be a 64bit driver. A;lso tried some Ricoh software, some Universal PL6 driver. No idea how to get it running and if it can run at all. Every help appreciated. Thought it can't be that complicated.
