You might try using a free bar code font for printing your bar codes
however bar code fonts generally produce poor quality bar codes that
are difficult to read. The primary purpose of bar coding is to save
someone the trouble of typing in data. If your bar codes do not read
then you have to type them in anyhow.
For freeware bar code fonts you might try

For printing bar codes from Access, you would be best off using a bar
code ActiveX control like the one fromTAL Technologies at the
following URL:

I would recommend that you download the demo of the TAL Bar Code
ActiveX control from the above URL and take a look at the sample
Access database that is provide with the demo.
