OT: Symbol barcode emits two lasers, not one.

[Dre G.]

I used to manage about 500 symbol scanners and a million square feet of 
wireless loving.. Imagine some of the challenges with that :P
There wasnt just one of me doing it but we had many other tasks as well to 
do.
My scanner stories could go on for years and years and years but I think I 
am done with the flashback for now

/me twitchs back to his own corner

PDF417, I forget which.

 The scanner users used to just bang them on the side of a package until they started working 
again.  Oh yeah, that'll fix it.   Wires used to break inside the cable casing all the time too.  
Lot of abuse can occur inside a package hub.  You should have seen the some of the damage to 
handheld scanners the drivers carried.  Same as the FedEx ones, in fact my old Co. merged w/ FedEx. 
 I had the lucky task of reprogramming the scanners and sending off the broken ones.
