How do I insert my logo into Caneco BT documents?

You need to copy your company’s logo in image format into the directory:

Caneco BT 5.3 and prior versions:
C:\Documents and Settings\All Users\Application Data\ALPI\Caneco\5.3\Labels

Caneco BT 5.4 and following versions:
C:\Documents and Settings\All Users\Application Data\ALPI\Caneco BT\5.X\Labels

It is then selected in Caneco BT, Tools/Preferences/Print menu.
