>I am writing a business application and part of it is to produce a purchase order with the vendors part numbers barcoded. I understand that code 39 or 3 of 9 would be a good standard. I am wondering if this purchase order is faxed to the vendor will the bar code be still of a good enough quality for the wand scanner to work properly. is there a font set available that would be better for my application ?
> another question I have is, should I add a "+" to the end of the part number so the wand scanner sends a carrage return to the computer after the part number is scanned?

For me, the issue revolves around the size of the bar code. The bigger the bar code the more readable.

Also, most scanners are configurable as to how they interpret the bar code.. i.e. they can be set up to append any kind of data at the end of the bar code. This is a better solution than adding a "+" as depending on the scanning equipment at the other end, it could be interpreted as a "+".

If you are not using a wand, but a CCD or Laser device, you can often get away with a "poorer" quality bar code.

To make it readable at the other end, double the size of the minimum readable bar code at your end.

This should work reliably. (Have done this with Intermec equipment, successfully.)
