It depends on answers on many questions:
Did you install OPOS drivers on your printer?
In ARPOS do you use OPOS drivers or Windows drivers to work with
printer? Please verify it: go to main menu - Configuration - Bill
Configuration - Printer.
Therefore in general there are two methods to work with EPSON and
other printers:
1. Via OPOS drivers.
2. Via Windows drivers.
The best method is to use the OPOS drivers.
Please read step-by-step instructions:

There are two major steps:
1. you should download and install CCO OPOS drivers
AND
2. install OPOS drivers provided by EPSON.
Then you have to check your printer with Epson SetupPOS utility.
This utility is usually installed with OPOS drivers from Epson.
Otherwise you can always download it from Epson's web site.
Start Epson SetupPOS utility. On Left tree click on Device -
POSPrinter - then right click on your printer and execute CheckHealth
interactive command.
This CheckHealth command should successfully run with your printer. It
means that your printers is correctly installed and it can be used
with other POS programs.
Normally only after that you should start ARPOS and go to main menu -
Configuration - Bill Configuration - Printer where you have to select
OPOS as connection method and specify LDN (logical device name) of
your printer that you see in Epson SetupPOS utility.
Therefore the recommending way is to use the OPOS drivers.
The second variant: use Windows drivers. Go to main menu -
Configuration - Bill Configuration - Printer and select Windows
driver as connection method. Again it's better to use Windows drivers
installed from Epson's CD than standard Windows drivers. If it does
not work with Windows drivers you can also use an alternative printing
module which uses Windows drivers in alternative way: go to main menu
- Configuration - Bill Configuration - Parameters and check "Use
alternative printing module".
