I have a Computing Scale PC-100 the same as the one from the link below:

Also i have Fiscal Cash Register, model: SY-50

My question is the following: How do i connect these two communicate with each other and with the computer so i don't have to use scale and cash register both each time when i sell something. Currently i first use the scale and then i enter measurement and code in the cash register.
Please tell me how much programming is involved here if it matters at all. Thanks
