After the most recent update (Sept 25) of 10.9.5, I'm getting a message "the disk you inserted was not readable by this computer" when connecting by USB printer cable. Yes, have rebooted, restarted, cleared printers etc. Now in Printers and Scanners my printer is not even recognized...no printer available. HELP!
iMac, OS X Mavericks (10.9.5)
I haven't experienced that, but I recommend you start with the usual maintenance procedures:
First, startup using Safe Boot, which does some repairs while starting. Just restart normally after that finishes. (And try adding a printer after that):
OS X: What is Safe Boot, Safe Mode?
If that hasn't helped, try Resetting the Printing System:
OS X Mavericks: Reset the printing system
Then try adding the printer.
Thank you very much. The safe boot worked, especially after I turned off the printer and unplugged the printer cable before rebooting in normal mode. Once I restarted in normal, I turned on the printer and plugged in the cable, and voila, printer recognized. Appreciate the help.
