I get that you can write the labels or print on sticky A4. This looks much more professional than a hand written label and is much easier that A4 labels. Not saying it’s cheaper than either but for the price it is currently it’s great.
Here's some printing labels for less than £5 (10 labels x 100 sheets) https://www.amazon.co.uk/Mailing-Address-Printer-Labels-Sheets/dp/B00FVSUSSU/ref=sr_1_3?ie=UTF8&qid=1523038987&sr=8-3&keywords=printing+labels
use my printer at work
Think i will just write it out by hand and tape it on, but handy if you have cash to throw in the bin
Why is your ink free?
