** IMPORTANT ** Please ensure you have some IT experience before attempting the installation of your Nexa PX700/PX900 Receipt Printer! How do I connect the Nexa Printer to my Computer? The Nexa PX700 & PX900 has a variety of ways to connect to your computer. This is because different POS software require different connection types. Thankfully the Nexa printers have all the bases covered, having a Serial port, USB port and Ethernet/LAN port as standard. Your POS software determines the connection type you need. If you are unsure which one to use, please ask your software provider. Serial or RS232 USB Port This printer is normally setup using one of the Two Scenarios below: 1. Direct Serial Communication (No Windows Driver needed MYOB Users): a. Via a Serial/COM Port connection b. Via a USB Port using a Virtual Serial/COM port 2. Windows Driver Communication (Non MYOB Users) A printer driver is installed, which appears in Windows Printers and Faxes just like a normal A4 printer. Your POS software will print via this Windows Driver: a. Via USB Port You will install a Virtual COM Driver AND a Windows Printer Driver. b. Via Serial Port - You will install a Windows Printer Driver ONLY! Scenario 1a Direct Serial Communication via a 9 Pin Serial/RS232 Port This setup is used if you have a Serial Port on your PC and a Serial Port for your NEXA Printer. This setup is for popular POS Software like: MYOB Retail Basics & MYOB Retail manager QUICKBOOKS Retail POS Software Follow this Process Carefully:
1. Do NOT connect your printer 2. Do not load any printer drivers at all 3. Reboot your computer 4. Connect your Printer to power and switch on (Do not connect to Computer yet) 5. Wait for the printer to power up 6. Connect your Serial cable from the printer to a spare Serial/COM Port on your PC 7. Go ahead and Setup you're printer in your POS software. IMPORTANT In your POS software, make sure the printer is pointed to the correct Serial port. This will usually be COM 1 or COM 2 when using a physical 9 pin Serial Port If your printer is printing funny characters like??@#$%, this is because the Baud Rate (printer speed) for the printer and the computer COM port is different. Simply make the PC COM port Baud rate the same as that of the printer (default Baud rate is 9600 bps) You can check your PC's COM port settings in Device manager (Windows Control Panel) under the Ports Setting. If you right click on the Port you can change the Baud Rate. Scenario 1b Direct Serial Communication via a USB Port using a Virtual COM Driver This is called a Virtual COM setup as we make the USB port act like a COM Port.
This setup is used if you have a USB Port on your PC and a USB Port for your NEXA Printer. This setup is used for popular POS Software like; MYOB Retail Basics & MYOB Retail manager QUICKBOOKS Retail POS Software We need the Virtual COM Software Driver. This driver turns the Nexa Printer's USB port into a COM PORT, which will allow your POS software to send instructions directly to the printer via COM1 or COM2 etc. So essentially the USB connection will behave like a COM/Serial Connection. Follow this Process Carefully: 1. Do NOT connect your printer 2. Reboot your PC 3. Download the Virtual COM Driver by clicking visiting our www.hotpos.com.au/support and clicking on the Nexa PX700 support page. 4. Now save the Virtual COM Driver File to your desktop. Remember where you saved it. 5. In this example we will assume you have the Windows 7 64bit operating system. 6. Unzip the downloaded Virtual COM Driver file (Note: The x86 folder is for 32bit and the x64 folder is for 64bit) 7. Power up your Printer but DO NOT connect to PC 8. Wait for Printer to power up 9. Now, connect the printer with the USB Cable to your PC. 10. You will see the following:
11. Navigate to the specific location you unzipped the Virtual COM driver file. Then select the file as per the picture below (note this file will be x86.inf for Windows 32bit users) 12. You may see the message below. If so just click continue anyway.
13. The driver will then install, click OK when finished. 14. This process is now complete. NOTE: The driver may say Device Cannot Start the USB connection/cable just needs to be disconnected and reconnected to resolve this. IMPORTANT Check your virtual COM port has been setup correctly: Navigate to Windows Device manager (Device Manager can be found in Windows Control Panel ) You will see the Nexa Virtual Serial Port with its COM port setting in brackets. At this stage take note of the COM Port number as you will need to point the printer to this port in your POS Software. EXPERT TIPS Sometimes the Virtual COM Driver installs on a high COM port number, like COM14. Most POS software only go up to COM6. To resolve this, you can change the Virtual COM port number in the Windows Device Manager (Above) like so: 1. Right click the Nexa Virtual Serial Port 2. Left click properties 3. Left click the PORTS Tab
4. Left click Advanced 5. Change the COM Port number to the first COM Port Not in use eg COM 2. 6. Click OK. If your printer is printing funny characters like??@#$%, this is because the Baud Rate (printer speed) for the printer and the computer COM port is different. Simply make the PC COM port Baud rate the same as that of the printer (default Baud rate is 9600 bps) Scenario 2a Windows Driver Communication with USB Port You will generally know a windows driver is required if the Receipt Printer setup in your POS software wants you to choose a printer from Windows Printers and Faxes or your POS Software might be running through your Internet Browser (Internet Explorer etc) If in doubt, ask your POS software provider if the software will need to print via a Windows Printer Driver If you are running Windows 32-BIT Follow this Process Carefully: 1.
