Hi babymum, so sorry for missing your post!
Do you want to print the categories you made (to use as flash cards)? If that's what you're looking for, just go to Little Reader's PRINT screen to print them out.
You may refer to either of these pages for detailed instructions on how to use the Print screen:
http://www.brillkids.com/littlereader/moreinfo.phphttp://support.brillkids.com/entries/20388416-How-to-print-flash-cards-in-Little-Reader**If you want to print the category title too, just check the box for "Print Cover" at the bottom of LR's Print screen and type in the title you want to use before you start printing out your flash cards.
If you mean you want to print a list of the categories you created, LR's Print screen doesn't support that type of printout. You can instead type your category list in Word or Notepad and print it out from there.
I hope this helps!
