[AccessD] Bar Code Printing/Scanning

...have a need to print bar codes on badges that can be easily and reliably 
scanned at a trade show entrance.

...the database is A2K3 but the data is merged to WXP to print the badges.

...the badge bar codes are printed with HP LJ 4050s

...printing the bar codes in Word using code 39 font works well but doesn't 
produce the enter/exit control codes

...also need to know if anyone has experience with a particular hand held 
scanner or manufacturer that you would ...or would not ...recommend.

...and how you've collected the data from the scanners.

...and anything else I should be aware of before leaping.

...anyone?
