Nexa provides a good quality receipt printers designed for Point of Sale. The earlier PX700 (GP-80250) has Serial and USB connectors, and the later PX700II (GP-80300) also has Ethernet built in and is faster.
Ensure you have the right Printer Driver
Note there are several different drivers around. We recommend downloading Drivers from our Evopos Portal at: http://evopos.com.au (Login, then select Portal / Downloads) or direct from the manufacturer site at: http://www.nexapos.com (Under Support).
Note: As at 26th Oct 2015 the driver name was: DR80VREN V10.exe dated: 5-Jun 2013.
Installing Printer with USB connection
Installing the driver for USB connections can be a bit tricky as there is a Serial to USB converter in the printer which needs to be installed before installing the actual printer driver (Same file).
Ensure paper is loaded first, then power on, and lastly connect to the computer
Run the Driver
Ensure the nearest Windows Version is selected (For Windows 10 use Windows 8)
Select the 'Install the Virtual USB to Serial converter' option first
Then find out what COM port has been allocated. You can do this by running Windows “Device manager” (Device Manager can be found in “Control Panel”). Under 'Ports (Com Lpt)' you should see the Virtual Serial Port with its COM port setting in brackets eg: 'GPrinter serial port (COM3). Take note of the COM Port number as you will need to point the printer to this port in the Printer Driver. Note: COM3 is the most common setting
Then select the 'Printer Driver' option. Ensure the port is set correctly as above
Once installed it should be visible in Devices & Printers (select from Start Menu in Windows 7 or earlier, or right click Start and select Control Panel on Windows 10)
Sometimes the Virtual COM Driver installs on a high COM port number, like COM14. To resolve this, you can change the Virtual COM port number:
In some rare cases you will also need to Restart the computer before it will work.
Installing Printer with Ethernet Network connection
Ensure paper is loaded first, then power on, and lastly connect to the network
Print out the current printer settings by switching on while holding the Print Feed button and then release
Make a note of the Printer current IP address (The Default is normally: 192.168.123.100)
Then check the Local IP Address and Gateway of the Computer. Select Run, enter CMD and enter IPCONFIG at the command prompt to see settings. The IP addresses must be in the same range (Normally the first 3 sets of numbers the same) to work.
If the IP address is not in the same range you must either:
1.Set the Printer IP Address in the same range as the Computer / Network. To do this you must temporally change the IP Address of the compter to the same range as the Printer. Go to Network, Network Adaptors, right click Local Area Connection and select Properties, then select the Internet Protocol (Version 4) line, select Properties, set to 'Use the following IP address' and enter an IP address and in the same range as the Printer. You can then run the Printer Ethernet Utility (you can download from Nexa or our Portal), confirm the current Printer IP (Check connection to confirm correct), and then enter the IP address you want to change it to. Then go back into the Local Area Connection and change it back.
2.Set the IP address of the Computer / Network to the same range as the Printer. If you do this you would normally need to change the DNS Server (Normally on the Router / Internet Modem) to use the new range and then restart the computers. You could also change manually by going into: Network, Network Adaptors, right click Local Area Connection and select Properties, then select the Internet Protocol (Version 4) line, select Properties, set to 'Use the following IP address' and enter an IP address and in the same range as the Printer.
Then run the Printer Driver program and accept the Licence agreement. Depending on the Driver you may have to confirm the Operating System, Printer model (on older drivers the model can be GP-8160(Cut)Series) and Connection method. In this case the connection method is Ethernet and we will need to select the Port. If the IP for the Printer is not shown select 'Add Port' and enter the Printer IP, normally the Port Wizard will say 'The device could not be Itentified' but just select Next, Finish and then select the Port created and select 'Install'.
Opening Cash Draw
The Printer has a RJ12 port (similar to a small phone plug) that can connect to a Cash Drawer for automatically opening it.
The normal system of opening the Cash Draw from Evopos is that Evopos sends a code direct to the Printer as specified in Settings / Workstation / Print Options / Simple Invoice.
It will only open the Drawer on Payment Methods that have the Open Cash Drawer option ticked. See Settings / System / Sales / Payment Methods.
Alternatively there is an option you can set in the Printer Driver settings so it opens the Draw at the start of each print.
