10.12.6 Combo Update

I must thank you all for your patience and help offered, but … I seem to have stumbled across a solution to this problem.

It’s nothing to do with Disketch.app. I didn’t understand how it could have been so.

I found the ‘solution’, which I don’t really understand, in a post on forum dated December 2014 on the BeLight Software site, after desperately Googling the problem. I'd already visited that site once but gave it a second go for some reason - grabbing at straws.

Here's the post I

(by mcaswell) I noticed that when I looked at the printer in the Printers & Scanners PrefPane, it listed "Kind: Canon MG7500 series-AirPrint". It occurred to me that perhaps my Mac was using a simplified AirPrint driver (intended for printing from iPads, etc.), which could explain why the CD print option was not there (since presumably no one would be printing CDs from their iOS device).

I deleted the printer, and then downloaded/installed the drivers from Canon's site (not sure if this step was necessary or not... the drivers may have already been there as part of the OS, but just not utilized). When I clicked on the + sign to re-add it, I selected it from the Nearby Printers list that pops up under the + sign, and noticed that it again was using the AirPrint driver.

I again deleted it, but this time when I added it, I didn't use the Nearby Printers list, instead choosing Add Printer or Scanner. It again chose the AirPrint driver, but I was able to select the correct driver (Canon MG7500 series) in the "Use:" pop-up menu.

Once I did this, I was able to print CDs wirelessly.

Yeah. Me too! I had never noticed a 'Nearby Printers list' previously, btw.

I had also, before the above, downloaded and reinstalled the latest available Canon driver for my printer. It was exactly the same version as had been previously installed. It had made no difference.

After going around in circles last week trying* to revive my printer's ability to print onto CDs, I found this morning that the double-sided printing feature was no longer an available option in the print dialogue box.

It seems that having the one disposed of the other. I spent a while venting, then discovered that I have 'two' printers. Alongside 'Printer:' in the print dialogue box it says 'Canon iP7200 series'. Clicking on the drop down arrows reveals another printer, also called 'Canon iP7200 series' !

Turns out that with one of them double-sided printing is an option, but printing onto a CD is not. On the other, printing onto a CD is an option, but double-sided printing is not. I can choose which 'printer' to use depending on which of the two options I need.

This is an example of superposition where a printer can be in two states at the same time. Folks, I have a quantum mechanical device!

I'll give it a go, Kappy.

Thanks for that comprehensive list Kappy.

I've made a copy of it for now. Have you seen the reply from PN2?

Thanks. I'll give that a go this weekend.

Have reinstalled the OS via the Recovery Partition. No change. Still can't print wirelessly onto CDs.

Then on the disketch set the wireless connection again. if necessary remove the unit from the mac, then reenter it again.

Do you mean uninstall the Disketch app & reinstall?

Thank you PN2, Happy and Lexiepex.

The problems is solved - for the time being.
