Can no longer see printer

Question

Can no longer see printer

I installed Mountain Lion on a partition so that I could continue to use my Canon Pixma MP600R printer and scanner. This arrangement has worked fine until the other day when the printer would not connect and was showing as unavailable. Nothing had been changed that may have caused this. I have tried reinstalling the printer drivers, re-adding the printer, and even reinstalling Mountain Lion. When I try to add the printer it simply does not show as being connected. Could it be the USB lead? I cannot try connecting with another lead as the printer end of it is a square connection. Thanks.

iMac (27-inch Mid 2011), OS X Mountain Lion (10.8.5)

Thanks Mike. I have tried as you suggested but the printer still does not appear for me to add it. The support page goes on to then suggest:-

Remove printer drivers

If the issue continues on your Mac after resetting the printing system, take these final steps to remove any currently installed printer drivers. These steps don't apply to AirPrint printers.

From the menu bar in the Finder, choose Go > Go to Folder. Type
```
/Library/Printers/
```
and click Go.
The Printers folder opens. Choose Edit > Select All, which selects all items in the Printers folder.
Choose File > New Folder with Selection, which puts all of the selected items into a new folder named New Folder With Items.

I have tried this but at step 3 I cannot choose > New Folder with Selection, as this is greyed out?

I would make sure that you're logged in as an administrator first. I would try a different administrator account, make a new one if you have to, you can delete it later.

You might try resetting the SMC How to reset the System Management Controller (SMC) on your Mac - Apple Support

and NVRAM How to reset NVRAM on your Mac - Apple Support

Finally I would try a different usb cable.

Thanks again. I have reset the SMC and NVRAM using a new administrator account but still cannot add the printer. I'll now try to find another cable that fits the printer and will post to let you know what happens.

I have now tried another cable that has been verified as working but the printer still does not show to be added. All the USB ports on my computer are working with other devices. Could it be the port on the printer? Any other suggestions as to how I can overcome this would be welcomed. Thanks.

Yes I have already tried a verified working cable as per my earlier post, although I was using the old cable when trying safe mode (having returned the other one to the person I borrowed it from). Were you suggesting I try the replacement cable in safe mode?
