after mac update (Sierra) duplex printing disabled
Hello,
I have a Canon MG3250, and after updating to the new version of Sierra (10.12.4), I cannot do duplex/two-sided printing: the two-sided option is grey and I cannot change it.
Before the update I could do it without any problem, I have downloaded and updated the driver for the printer, still same problem.
I have re-installed my printer but it doesn't change anything.
And I have the same problem with other printers that used to do duplex printing
Any suggestion?
Thanks
