After a quick read of the instruction booklet it is easy to create labels. I would recommend making and keeping a few demo labels to illustrate the sizes/styles available. Also access a pdf copy of the booklet and then print a larger version of the symbols table, the paper copy is very small. A slight irritation is with the font that prints lower case letters with a tail e.g 'y' in a squashed manner, think carefully about the text to use or use only uppercase to avoid this issue. The delivery was very quick, next day after order processed. The unit works well using an existing suitable adaptor, so no information on battery use. Very happy with the purchase, the delivery service, and the follow up call to check that all was well.
