The LW-PX300 can't print graphics (though it has a library of bar codes and symbols for industrial and professional use), and it prints pretty slowly. But its labels look great and work fine.
We also appreciate the touchscreen that the Adventurer 5M has, which makes it a lot easier to navigate and consume information about the print, which can be a bit frustrating on cheaper printers.
For each one of my in-depth reviews, I spend around eight hours evaluating everything from design and build, to usability and, of course, print quality, before giving each product its overall rating.
