Read the manual for the cash drawer; anything else is a guess.

If the drawer is connected to the printer, then you will likely need to read the manual for the printer.

Look in the code for 'print, or look in the docs, and figure out the call that opens the drawer. However, is it possible that not being able to open the drawer without printing is by design ?

You should talk to the people who created it - they should provide technical support and will know more about their product than we will. If they don't, then find another supplier and demand your money back!

We have no idea what drawer you are using, so we can't tell you exactly what to do!
