User manual

To use virtual printing, the Horizon administrator must enable the virtual printing feature for the remote
desktop. This task includes enabling the Virtual Printing setup option in the agent installer, and can include
seing policies regarding virtual printing behavior. For more information, see the Seing Up Virtual Desktops
in Horizon 7 or Seing Up Published Desktops and Applications in Horizon 7 document.
Procedure
1 In the Windows 7 or Windows 8.x remote desktop, click Start > Devices and Printers.
2 In the Devices and Printers window, right-click the default printer, select Printer Properties from the
context menu, and select the printer.
Virtual printers appear as <printer_name> in single-user virtual machine desktops and as
<printer_name>(s<session_ID>) in published desktops on RDS hosts if View Agent 6.2 or later, or
Horizon Agent 7.0 or later, is installed. If View Agent 6.1 or earlier is installed in the remote desktop,
virtual printers appear as <printer_name>#:<number>.
3 In the Printer Properties window, click the Device Setup tab and specify which seings to use.
4 On the General tab, click Preferences and specify which seings to use.
5 In the Printing Preferences dialog box, select the dierent tabs and specify which seings to use.
For the Page Adjustment advanced seing, VMware recommends that you retain the default seings.
6 Click OK.
Using USB Printers
In a Horizon environment, virtual printers and redirected USB printers can work together without conict.
A USB printer is a printer that is aached to a USB port on the local client system. To send print jobs to a
USB printer, you can either use the USB redirection feature or use the virtual printing feature. USB printing
can sometimes be faster than virtual printing, depending on network conditions.
n
You can use the USB redirection feature to aach a USB printer to a virtual USB port in the remote
desktop as long as the required drivers are also installed on the remote desktop.
If you use this redirection feature the printer is no longer logically aached to the physical USB port on
the client and this is why the USB printer does not appear in the list of local printers on the local client
machine. This also means that you can print to the USB printer from the remote desktop but not from
the local client machine.
In the remote desktop, redirected USB printers appear as <printer_name>.
For information about how to connect a USB printer, see “Connect USB Devices,” on page 47.
n
On some clients, you can alternatively use the virtual printing feature to send print jobs to a USB
printer. If you use the virtual printing feature you can print to the USB printer from both the remote
desktop and the local client, and you do not need to install print drivers on the remote desktop.
PCoIP Client-Side Image Cache
PCoIP client-side image caching stores image content on the client to avoid retransmission. This feature
reduces bandwidth usage.
The PCoIP image cache captures spatial, as well as temporal, redundancy. For example, when you scroll
down through a PDF document, new content appears from the boom of the window and the oldest content
disappears from the top of the window. All the other content remains constant and moves upward. The
PCoIP image cache is capable of detecting this spatial and temporal redundancy.
