Ricoh SP 150SUw printer stopped working after updating to macOS

I have exactly the same problem. When I do everything according to the instructions I get "Software for the printer is missing. Contact the manufacturer for the latest compatible software."

I was able to fix this. You need actually to rename the file via peoperies function. By default MACOS doesn’t show this extension

What program do I need to edit RICOH_SP_150.ppd?

Dude, worked like a charm!, you have been a life saver on this.

Stuck with the printer issue for MONTHS and was such a simple solution! Thank you very much, seriously, you made my day!

Happy that it helped!

Worked perfectly, thanks a lot.

Thanks a lot! I made a simple mistake: copy and past doesn't work - you have to write it! Now the printer works fine! Grazie mille!

Read the forum better and you will find the solution.

you don't have to use the Terminal.

use GO TO FOLDER and then type the command and you will find what you are looking for...

I found the folder, but it’s empty although I have installed the driver.

If you have installed the latest available RICOH drive version correctly,

it is impossible not to find RICOH_SP_150SUw.ppd and RICOH_SP_150SUw.ppd.O

Thank you! Worked exactly as you advised. The only confusion I had was that I tried to use Go TO in the BBedit, and then I saw your further screenshots and I realised it was GO TO FOLDER in FINDER. The rest worked perfectly just the name of the file "RICOH_SP_150SUw.ppd" was slightly different but it did not make any difference.
