One of my customers bought an M401. We need to have them print bar codes, so they bought an HG282DJ stick and installed it. Bar codes aren't printing. My understanding was that there was no setup to this thing; you just plugged it in and it worked. HP seems to have no documentation on installation (or anything else regarding the HG282DJ), which further reinforces that notion. Yet the bar codes don't print. What am I overlooking here?
