Web POS | CP ConneX - Windows Host Installation


ClickPOS have designed an application that will allow our POS system using other (Non Internet Explorer) browsers and devices to print to a legacy Epson printer that once could only be used with Internet Explorer. This included opening of the cash drawer.

It can also be used to print labels to the Zebra Label printer allowing any device connected to the network ip range to produce labels without being directly connected.

ClickPOS ConneX will be the base product for many new and exiting features in the future.

Important Information

Currently EPSON and many other legacy POS printers use a program called OPOS to communicate between the Internet Explorer web browser and the printer itself.

There is a valid reason for this due to communication security logistics between the 'WEB BROWSER' and the hardware such as "PRINTERS, CASH DRAWERS, etc..'

OPOS is required to be installed and functional on a Windows based PC for this application to operate correctly. A Successful OPOS health check must be performed to ensure printer to OPOS communication. Refer: OPOS Installation Section for more information

The same applies to the Electronic Cash Drawer attached to the Printer. All health checks must be performed successfully 

If you have not installed EPSON OPOS and the POS printer and cash drawer are not setup; stop and proceed to install and setup OPOS before continuing on with this installation.
