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.

Confirm that the VGA Printer device is receiving images from the VGA source by logging into the VGA Printer Web admin interface (see

“Logging Into the VGA Printer Web admin interface” on page 18

) and confirming that a captured image appears.

If a captured image does not appear, check the VGA source to make sure it is transmitting a VGA image. Also check the cable between the VGA Printer device and the VGA source to make sure it is connected correctly.

Using the Network Discovery Utility to

Find the IP Address of the VGA Printer

Device

You can use the Network Discovery Utility on a Windows PC to find the VGA Printer device and its IP address on the network.

You can also use the Network Discovery Utility to connect to the

Web admin interface.

The VGA Printer device must be assigned an IP address on the network to be able to find and print to network printers. It can get an IP address from a DHCP server if there is one on the network.

If the network does not have a DHCP server, see “If the Network

Doesn’t Have a DHCP Server” on page 20 .

This section assumes that the network has a DHCP server and that the DHCP server gives the VGA Printer device an IP address on the network.

Changing the VGA Printer IP Address

You can change the VGA Printer IP address at any time. You may need to change the IP address so that PCs on the network can connect to the VGA Printer Web admin interface and so that the

VGA Printer device can connect to network printers.

• If the network does not have a DHCP server you will most likely need to change the VGA Printer IP address.

• If the network does have a DHCP server you might also want to change the VGA Printer IP address if you would rather the the VGA Printer device have a static IP address instead of a dynamic address assigned by the DHCP server.

• You can also change the VGA Printer IP address even if the

DHCP server has assigned an IP address. If for some reason the DHCP server goes down, you can switch the VGA Printer to connect using the static IP address.

Triggering Printing From a Third-Party

Application

You can integrate the VGA Printer device with a third-party application or a script that “touches” the Print Page Now URL to trigger the VGA Printer device to print the currently captured image. If the VGA Printer IP address is 1.1.1.1 a print URL could be: http://1.1.1.1/admin/submit.cgi?cmd=prnow

.

You must also include the admin user name and password. To do this, you can combine the URL with authentication using a tool such as

Wget

. For example, if you use

Wget

and the VGA Printer

Web admin interface password is vga_print the syntax could be: wget --http-user=admin --http-passwd="vga_print"

“http://1.1.1.1/admin/submit.cgi?cmd=prnow”

Color

Transformation

Shows the current default printer. This is the printer you are configuring the VGA Printer device for.

In some cases, you may want to transform some of the colors in the print of the captured image. For example, if you are capturing images with a dark background and white text you might want to select

Invert all colors

so that in the printed image the background is light and the text is dark.

You can also select

Invert black only

, if you want to keep the colors the same in the printed image but convert black in the captured image to white in the printed image.

You might want to select this option if the captured image has a lot of black in it.

If you select

Invert all colors

or

Invert black only

you can also enter a %

Page Fit

Annotation

The VGA Printer device prints one image per page and scales captured images up or down to fit on the page size configured for the printer.

Fit image keeping original aspect ratio

is the default setting. This setting scales the image to fit on the printed page without distorting the image. This setting may result in white space on the printed page if the image doesn’t match the shape of the page.

You would usually select this page fit option to avoid distortion of the image if the shape of the captured image is very different from the shape of the printer page.

Select

Fit image to fill the whole page

to scale the image to fill as much of the printed page as possible. Usually you would only select this option if the captured image closely matched the shape of the printed page. If the captured image was a much different shape than the page this page fit option could distort the image an unacceptable amount.

You can select

Add annotation to the printed page

to add text to each captured image printed by the VGA Printer device. The text appears at the bottom of the page. Add the text for the annotation to the

Changing VGA Printer Sound Volume

You can configure the VGA Printer device to produce a sound each time a print request is received. You can also set the sound volume level. Set sound volume to 0 to turn sound off.

You can set the sound volume to 10, 25, 50, 75, or 100. Try different sound levels until you find the one that works for you.

Configuring VGA2USB Adjustments

The VGA Printer device automatically adjusts image capture settings every time it starts up. This automatic adjustment is repeated every 60 seconds during operation. You can change the interval between automatic adjustments if you want them to occur more or less often.

Normally you would not have to make manual image adjustments. However, you may have special requirements or for other reasons have image quality problems that can only be fixed by making manual adjustments.

The Web admin interface contains most of the information that you need to make image adjustments including a brief description of the affect of each adjustment and the adjustment range.

Because image adjustments are made automatically there are no default image adjustment settings. Also, changing image adjustments means making relative adjustments from the settings auto configured by the system.

To configure image adjustments from the Web admin interface

Configure vertical shift to offset the captured image position. For example, a captured image shifted slightly downward (vertically), can be corrected with minor adjustments to the vertical shift settings.

Increasing or decreasing the value entered in the

Vertical Shift field shifts the image up or down.

Configure horizontal shift to offset the captured image position. For example, a captured image shifted slightly to the right (horizontally) can be corrected with minor adjustments to the horizontal shift settings.

Increasing or decreasing the value entered in the

Horizontal Shift field shifts the image to the left or right.

Configure Phase (also called sampling phase) to adjust the horizontal resolution of the image.

Improperly adjusted phase will result in a fuzzy image. You can adjust the sampling phase in small steps until a sharper image is displayed.

PLL adjustment

Offset and

Aspect

Ratio

Configure PLL to adjust the vertical synchronization properties of the image. The

PLL adjustment may need to be changed when there is a repetitive distortion or blurriness on the horizontal axis of the image. You can adjust the PLL setting in small steps until a sharper image is displayed.

Use the offset and gain controls together to optimize image quality. Increasing gain amplifies weak signals but also increases noise.

Increasing offset reduces background noise but also reduces the overall signal.

Balance offset and gain to achieve the best quality image. You should adjust these settings by the smallest values possible to achieve the best results. You can compensate for a large change to one by making a large change to the other, but setting both offset and gain to high values can result in poorer video quality.

Set the aspect ratio of the captured image. The default aspect ratio is 4:3. You can change the aspect ratio to wide mode so that the device can accurately capture wide aspect ratio VGA modes.

It's not always possible for the Epiphan device driver to distinguish between video modes when they have the same number of rows, for example, 1024x768 and 1280x768. You can change the aspect ratio to Wide Mode if you want the driver to choose wide video mode in these situations.

Controlling Print Jobs

Controlling Print Jobs

When you select to print a captured image, the VGA Printer device creates a print job. The print job is added to the current or default printer’s job queue and then sent to the printer.

If you send captured images faster than the printer can print them, multiple print jobs are added to the printer’s job queue. The

VGA Printer device then sends the print jobs to the printer one at a time in the order in which you selected to print them.

All print jobs in the print queue have a unique ID which consists of the printer name followed by a consecutive number. For a given printer, the VGA Printer device prints jobs in ID order. If a print job with a lower ID is stopped, print jobs with higher IDs will not print. You must restart, cancel, or move a stopped print job to print the jobs below it in the print queue.

Page 70 Epiphan VGA Printer

5. Advanced Printer Configuration

Figure 39:Example print queue

Controlling Print Jobs

You do not normally have to work with VGA Printer print jobs or print job queues, but working with print jobs can be useful for checking the status of print jobs and for solving some printing problems. Also, if a printer is turned off or disconnected and you send print jobs to it, the print jobs are stored in that printer’s print queue. You can either move those print jobs to another printer or when the printer is connected or turned on again, the VGA

Printer device sends the stored print jobs to the printer. After the printer is restarted, you may have to go to the print queue and restart print jobs for them to print.

5. Advanced Printer Configuration Network Protocols Supported By the VGA Printer device

Network Protocols Supported By the

VGA Printer device

The VGA Printer device supports most network printers that use the following protocols:

• AppSocket/HP JetDirect

• Internet printing protocol (ipp or http)

• line printer daemon (LPD or LPR)

Printer discovery is currently accomplished using the SNMP protocol; however, future versions of CUPS will also include support for multicast DNS service discovery as well.

See the CUPS document Using Network Printers for more information about network printing including a table of common device URIs.

Note:

The VGA Printer device does not support printing to

Windows network shared printers.

AppSocket/HP JetDirect

The AppSocket protocol (sometimes also called the JetDirect protocol, because of its origins with the HP JetDirect network interfaces) is the simplest, fastest, and generally the most reliable network protocol used for printers. AppSocket printing normally happens over port 9100 and uses socket URIs: socket://ip-address-or-hostname socket://ip-address-or-hostname?waiteof=false socket://ip-address-or-hostname:port-number socket://ip-address-or-hostname:port-number?waiteof=false

Examples: socket://192.168.20.34

socket://MyPrinter?waiteof=false socket://192.168.34.56:9100 socket://10.10.10.23:9100?waiteof=false

User Guide Page 75

5. Advanced Printer Configuration Network Protocols Supported By the VGA Printer device

The “waiteof” option controls whether the socket backend waits for the printer to complete the printing of the job. The default is to wait.

Internet Printing Protocol (ipp or http)

IPP is supported by some network printers and print servers. IPP support may be inconsistent so you should only use IPP when the vendor actually documents official support for it. IPP printing normally happens over port 631 and uses the http or ipp URIs: http://ip-address-or-hostname:port-number/resource http://ip-address-or-hostname:portnumber/resource?option=value http://ip-address-or-hostname:portnumber/resource?option=value&option=value ipp://ip-address-or-hostname/resource ipp://ip-address-or-hostname/resource?option=value ipp://ip-address-orhostname/resource?option=value&option=value ipp://ip-address-or-hostname:port-number/resource ipp://ip-address-or-hostname:portnumber/resource?option=value ipp://ip-address-or-hostname:portnumber/resource?option=value&option=value

Examples: http://192.168.20.1:631/ipp/ http://MyPrinter/ipp/port1 http://10.10.10.23:631/ipp?compression=gzip ipp://192.168.22.34/ipp ipp://OurPrinter/ipp/port3

Page 76 Epiphan VGA Printer

5. Advanced Printer Configuration Network Protocols Supported By the VGA Printer device

Line Printer Daemon (LPD or LPR) Protocol

LPD is supported by many network printers. LPD printing normally uses port 515 and lpd URIs: lpd://ip-address-or-hostname/queue lpd://ip-address-or-hostname/queue?option=value lpd://ip-address-or-hostname

/queue?option=value&option=value

Examples: lpd://192.168.45.123/queue lpd://MyPrinter/queue?banner=on
