The Comarch ERP Optima program communicates with the local computer using the drivers included in the Comarch ERP Optima SaaS application.
The component for Support for connection to a local computer is responsible for the operation of all subsequent drivers. All possible exports/imports from the Optima level, as well as the service of signing e-declarations/JPK are handled by the Data exchange with a local computer. According to their names, other drivers are responsible for fiscal printers, cash registers and payment terminals.
Caution
Comarch ERP Optima SaaS application, when launched, verifies whether new versions of the drivers are available. In order for everything to work properly, you should always update the selected drivers.
Hint
In the case of fiscal printers, cash registers and payment terminals, it is important to correctly configure the Comarch ERP Optima program, which is described in the Optima help.
Caution
Using e-declarations/JPK, it is important that the electronic card software is in the latest version made available by its supplier. In the case of a 64-bit system, it may be necessary to also install the software for the 64-bit version of the card.
