Canon introduced a new software for printing, based on their Layout plugin. The new software called Professional Print & Layout (current version 1.1.0) can be used as standalone printing software or as a PhotoShop plugin. It takes a little time to understand it's concept of slots and pages, but it is neccessary to use the automatic nesting layout. Color management functions are the same as in Print Studio Pro. There is a switch to Soft Proof the print preview. Standalone version is a great printing software for images prepared in Affinity to print on Canon PRO printers.
I'm not sure if Pattern Print is implemented in that software, too. Tom
