I have another question for you mike: in this lines
---------------------------
incheswide = 1.5 ' desired width of barcode
incheswide = incheswide / 95
pixwide = Printer.ScaleX(incheswide, vbInches, vbPixels)
PrintBarCode "639382000393", 1, 8.5, pixwide
----------------------------
Should the pixwide parameter be always a fixed size for the barcode? For
example: If you send a 2 inches in the incheswide, should the barcode
always be 2" wide no matter how many digits the barcode have? I'm not sure
if I made something wrong, or it's right so, but it sometimes print a
barcode 1.6" wide or 1.8" wide, or 2 or 2.2" wide. So, please let me know
if that's normal. I guess it is as it finally print the lines the wide it
can.
Thanx, M

Actually the code that I posted was designed specifically to print UPC
(Universal Product Code) barcodes. These UPC barcodes (apart from the
special "zero suppressed" versions) always contain 12 digits, and each of
those digits has a width of seven "thin lines". The group of twelve digits
therefore is always the exact width of 12 x 7 = 84 "thin lines". In addition
there are some start, middle and end codes that consist in total of 11 thin
lines. The entire UPC barcode is therefore *always* 95 "thin lines" wide. If
you want to print codes that contain a different number of digits them you
will have to adjust the "95" in the above code accordingly.

Also, the UPC barcode only contains digits (0 to 9). The code I posted is
not designed to deal with other types of barcode (although it would of
course be possible to modify it so as to accommodate such codes with a
little extra work).
