One thing that is clear is that today the PDF it is very widespread and millions of people use it every day. In the teaching world, which is where I work, this type of format is very important and that is, the Ministry of Education has decided that Microsoft Office has nothing at all, so if I want to work in Word, for example, and take the files to my work center to use them I must print them in PDF.
As you already know, from macOS you can make PDF prints in a very simple way from the print box itself in any application that allows it.
Now, when you click on File> Print, in the dialog box that appears you can see, in the lower left, that there is a drop-down with the acronym PDF. By clicking on this drop-down you can select Save as PDF ... after which the system will ask you Name the file and then say where you want to save it.
When you do this on a few occasions you can take the time to follow all these steps, but when you do many a day it is best to create a workflow for which in that same menu of the print window, in the PDF drop-down let's click on Edit menu ... A window is automatically displayed in which we can create a workflow by pressing the + sign.
When pressing the + we must select the location where we want the PDF files to be saved automatically. For this we must create a special location. In my case, I have created a new one called PDF Files within the Documents folder. It is a folder that being in Documents is synchronized with iCloud and therefore with the rest of the devices that I have.
I have also dragged that folder to the Dock on the right side to have it accessible at all times. From now on, all I have to do when I want something in PDF is click on File> Print> Dropdown> PDF File
