Q: HP Laserjet P1102w by USB "The disk you inserted is not readable by this computer"

when i connect a HP P1102w printer i get the message The disk you inserted was not readable by this computer." The print…

Or you could try the P1100(w) driver.

According to an ASC member who claims to work for HP, this issue can be resolved by repairing the permissions of the startup volume in Disk Utility. I can't confirm, but it has apparently worked in at least one case. It has also reportedly been resolved by starting the computer in safe mode with the printer disconnected.

Hi Shapley,

Repairing the disk permissions can be done as following:

1. Open the the Applications folder.

2. Go to the Utilities folder.

3. Double-click on Disk Utility.

4. Select the hard drive containing the boot volume.

5. Go to the First Aid tab and select Repair Disk Permissions.

Note: This process may take several minutes depending on the Mac and amount of permissions that need to be repaired. The Progress Log will indicate when the process has been completed.

Next reboot your Mac and try plugging the USB again.

If the same persist, a such may also happen due to a conflict with the HP Smart Install feature which is Windows Based only and being wrongly read by the Mac, in order to resolve a such a Windows based PC will be required. any laptop should meet the purpose, the printer will be installed automatically by connecting the USB.

Next update and install the latest firmware below:

Next follow the HP Smart Install Control Utility below: Select the Printer and follow the on-screen steps to disable the feature for the printer.

NOw plug the USB back to your Mac and check for any difference

Please let me know of any change,

Thank you very much! This saved mine!

In OSX EL Capitan, there is no more option "Repair Disk Permissions", what to do now?

Found solution: http://osxdaily.com/2015/11/04/verify-repair-permissions-mac-os-x/

Fixed for me.

Repairing permissions did not fix it for me, instead updating printer firmware did the trick.

Also, this problem only existed through usb wire connection and not with the wireless connection, so i connected wirelessly and updated the firmware, restart and usb cable connection works normally again. Hope this helps.

I finally managed to disable this setting (HP Smart Install) - what a pain it was! Now it's working fine.

Shlomi's advice won't work with El Captain.  Go to this link: http://osxdaily.com/2015/11/04/verify-repair-permissions-mac-os-x/.  There are step by step instructions.  I don't know Terminal at all, but I still managed to fumble my way thru it.
