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.

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 % invert threshold
value to control the brightness of the printed
inverted image. The higher the %invert
threshold the brighter the image.
Note: Color transformations affect the
printed image only and not the captured
image displayed on the VGA Printer Web
admin interface.

4. VGA Printer Web admin interface Configuring the VGA Printer device
Page Fit 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.
Annotation 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 Annotation text
field.
You can also select Include timestamp to the

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

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.

Adding a Printer That the VGA Printer Device Cannot Find Automatically
The VGA Printer device can usually automatically find any
printer that is turned on and either directly connected to the VGA
Printer device or connected to the same network as the VGA
Printer device. However, if the VGA Printer device can’t find a
printer that you want to add, you can use the procedures in this
section to add and configure the printer manually.
You can also use these procedures if you want to add a printer
that is not currently connected to the to the VGA Printer device or
the network. For example, if you are moving the VGA Printer
device to a new location or network, you can add a printer that is
at the new location before you move the device.

This section contains two procedures. You can use the first one,
“Adding a Printer Manually” on page 58, if the VGA Printer
device can’t find a printer that you want to add. You can use the
second procedure, “Adding a Printer Using a PPD File” on
page 64, if the VGA Printer device can’t find a printer that you
want to add and you have a PPD file for that printer or if you
would like to attempt to get a PPD file for that printer.
Adding a Printer Manually
Use the following procedure to manually add a printer. Before
you start this procedure you should know the following:
• The name and manufacturer of the printer.

“Adding a Printer That the VGA Printer Device Cannot
Find Automatically” on page 57.
• To set a printer to be the default printer, see “Selecting the
Default Printer”.
Selecting the Default Printer
If you have added more than one printer, you may need to
change the printer that the VGA Printer device prints to. You
change the printer by making the printer that you want the VGA
Printer device to print to the default printer.
Also, if you delete the printer that the VGA Printer device was
printing to, you may need to select a default printer.
Note: You don’t always have to select a default printer. Setting
the default printer is available if you want to change the printer
that the VGA Printer device prints to, or if Configure VGA
Printer displays the message Error: printer is not configured!.
Only one printer can be the default printer. If the default printer is
turned off or disconnected, print jobs are stored in that printer’s
print queue. You can either move those print jobs to another
printer, or the stored print jobs will be printed when the printer is
connected or turned on again. You may have to start the print
jobs manually, see “Controlling Print Jobs” on page 70).

5. Advanced Printer Configuration Controlling Print Jobs
Figure 38:The default printer
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 Controlling Print Jobs
Figure 39:Example print queue
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.
To view an individual printer’s print jobs
1 Log into the Web admin interface.
2 Scroll down to the Configure VGA Printer section.
3 Select Printers configuration and jobs control.
The Printers page appears.
4 To see the print job queue, select the printer icon for the
printer.

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:port-
number/resource?option=value
http://ip-address-or-hostname:port-
number/resource?option=value&option=value
ipp://ip-address-or-hostname/resource
ipp://ip-address-or-hostname/resource?option=value
ipp://ip-address-or-
hostname/resource?option=value&option=value
ipp://ip-address-or-hostname:port-number/resource
ipp://ip-address-or-hostname:port-
number/resource?option=value
ipp://ip-address-or-hostname:port-
number/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
