Access does not provide any bar code printing functionality however
there are a number of add-ins that you can use to print bar codes in
an Access report.
The easiest and the best solution would be to use a bar code ActiveX
control. You could probably use a bar code font however bar codes have
a start pattern, a stop pattern and a check digit that must be
calculated. If you use a bar code ActiveX control, these will all be
taken care of for you automatically. You can also "bind" an ActiveX
control to a data source so all you need to do is drop the control
onto your report, set a couple properties and start printing.
The best bar code ActiveX control on the market is available at the
following URL:

You can download a demo version of the product from the above URL and
the demo even comes with a sample Access database that demonstrates
how to use it in Access.
