This product has mixed reviews - people either love it or they hate it.
My initial observations:- It makes a lot of whirring noises - I hope this doesn't mean that it's going to wear out quickly. I like the fact that it can do double-sided printing. I like the fact that the menu screen is easily readable, with the printer on the floor underneath a telephone table. I don't like the fact that I can no longer see a print preview when printing from Notepad. I will use WordPad from now on. I prefer to not use "fancy" word processors like Microsoft Works Word Processor or Microsoft Word for simple documents like lyric/chord sheets. I can control all functions from my lap-top. Although the product has wireless capability, I'm using a USB cable, as with the F380.
Having imported an existing lyric/chord sheet into WordPad, I've reduced all margins to 3mm, as the HP 3520 adds borders by default. I've also had to use bold face to make the text as easy to read in dim light (typical open mic night setting) as the old sheets.
