I have a barcode scanner hooked up to excel. It decodes the encoded
text in the barcode it scans. The barcodes scanned may have up to
40-50 lines and 600 + characters of data. It will all stay in column A
and could populate all the way down to line 40-60. I'm trying to write
a macro for this with not too much luck.

When the information is scanned, the macro needs to start at A1 sense
how many cells were populated with data, maybe it fill A1 - A12 or
maybe A1-A60, it needs to auto prints those cells, then erases the
information that was scanned in and awaits the next scan, and does it
all over again until i stop it. It only prints once when it receives
new data.

Example: Basically its an autoprint as if you were to do a price check
in a store. you put the item under a scanner and the screen shows you
the price when its scanned, how ever instead of the screen output i
want it to print to a printer.
