[Affinity Design (printing multiple version)]

Hi!
Say if i would like to send it to a friend to print- would the version be printable as well? Would 1 jpeg be able to do the job? Or must I manually make different copies of it. That's my main question 

Thanks,
Keith

[Affinity Design (printing multiple version)]

I have an A4 artboard that I would like to print. However, I wanted to print in other dimensions like A3, A5 and other printing options. So far I had to manually copy and paste all my designs  from  one A4 artboard to anoter artboard and resizing it accordingly. Is there any other more efficient and effective method that I can use that allows me to export say a single A4 artboard into  different copies? 

[Affinity Workbook]

Hi- I wanted to ask about the Affinity workbook series- it started in 2016. 
In 2020 - is it still up to date? Should I buy it? I am thinking of purchasing it to speed up the learning curve but I would like to know if its still relevant today
