1. Introduction

1. Introduction
You can use the VGA Printer device to print any VGA or DVI-A display to any compatible printer with the push of a button or the click of a link on a web interface. The VGA Printer device can easily and cost-effectively capture images displayed on computer screens, or generated by medical equipment, microscopes and other specialized imaging products that have VGA or DVI-A output. While these devices may support printing, none is easier to set up or more effective than the VGA Printer device.
No special hardware is required just the VGA (or DVI-A) source and a printer that supports USB 1.1 or 2.0. You can also print to most network printers. Capturing and printing VGA or DVI-A images requires the following components:
• A VGA or DVI-A video source to capture images from.
• An Epiphan VGA Printer device that captures images from the video source and sends them to a printer.
• One or more printers to print captured images.
The VGA Printer device combines an Epiphan Frame Grabber and a computer in a small appliance. The Frame Grabber captures images. The computer records images captured by the Frame Grabber and can send captured images to one or more configured printers. The printers can be connected directly to the VGA Printer device with a USB cable or they can be network printers connected to the same network as the VGA printer.
Note: The VGA Printer Frame Grabber is equivalent to a VGA2USB or VGA2USB Pro that has been optimized for the VGA Printer device.
The computer also provides the VGA Printer network setup and printer configuration settings, and the VGA Printer .Web admin interface. You use the VGA Printer Web admin interface to configure the VGA Printer device and to view and print captured images.

Configuring and operating the VGA Printer device from the Web admin interface is simple. You can connect to the Web admin interface with any web browser and configure settings such as the VGA Printer network configuration, printer settings, and image capture optimization.
The VGA Printer device can also get network settings from a DHCP server if there is a DHCP server on the network.

Adding Printers

In most cases, adding a printer to the VGA Printer device is quick and easy, especially if the VGA Printer device can automatically find your printer.
A wide range of printer options, print job settings, and other functions are available if you require them. But in most cases once you have used the VGA Printer device to automatically find and configure a printer you do not have to spend much time working with the printer configuration.
While there are a lot of settings and options, in most cases you do not need to use them. However, they are available for advanced users or if you have special requirements.

1. Introduction Printing Captured Images
The VGA Printer device is compatible with most printers. If you connect a printer to a VGA Printer USB port or if a network printer is connected to the same network, the VGA Printer device can usually find the printer and after a few simple steps you can be printing captured images to it.
Figure 2: Finding available printers
You can easily add more than one printer to the VGA Printer device and then select one of them to use. The VGA Printer device remembers all of the printers that you have configured. This makes it easy to move the VGA Printer device to different locations and either add a new printer or print to a previously added printer.
As well, if you have special printer needs or want to print to a printer that the VGA Printer device cannot find or does not automatically support, the VGA Printer device supports uploading PPD files or creating custom printer configurations.

Printing Captured Images

You can print captured images by pressing the Print button on the VGA Printer device. You can also print from the Web admin interface. Finally you can automate print requests using an RS-232 interface or by using a custom VGA Printer URL.
User Guide Page 7
1. Introduction About This Document
The VGA Printer device displays the current captured image on the Web admin interface so that you can preview the image before you print it. You can also use the VGA Printer Web admin interface to add annotations to printed images and to adjust image capture settings and printer settings to optimize the printed image quality.
The VGA Printer device queues print jobs which means you can continue to print captured images without having to wait for the previous print job to finish.

RS-232 Integration

You can integrate the VGA Printer device with control equipment that uses an RS-232 interface. You can use this RS-232 interface to trigger the VGA Printer device to print the current captured image by sending a PRINT command over the RS-232 connection. The PRINT command must be terminated with an LF (ASCII code
10). Connect your control equipment to the VGA Printer using a
standard RS-232 null-modem cable. (such as Belkin Serial File Transfer cable part number F3X171-10). You must use an RS-232 serial adapter to connect the RS-232 null-modem cable to one of the VGA Printer USB ports.
The VGA Printer package does not include an RS-232 serial adapter but you can purchase one from Epiphan as an optional accessory.
Use the following serial port configuration for the RS-232 connection:
