How Secure Global Desktop printing works

Secure Global Desktop lets users print from Windows, X and character applications to a printer attached to their client device. Secure Global Desktop does this by co-operating with the lp or lpr UNIX printing system on the Secure Global Desktop server and the native printing system on the application server.

When a user prints, the print job is sent from the application server to the Secure Global Desktop server. The Secure Global Desktop server then sends the print job to the client device, which sends it to the user's printer. Secure Global Desktop printing uses distributed printing which means that print jobs are sent to the Secure Global Desktop server which is hosting the application's emulator session.

If the format of the print job used by the application server is different to the format needed by the client device, the Secure Global Desktop server converts the print job before sending it.

How users manage Secure Global Desktop print jobs

Users manage their own print jobs from the Printing bar on the webtop:

	When documents are printing, the webtop tells them how many print jobs are in the queue. Click Pause to temporarily stop printing. The printer icon changes to show you when printing is paused. If the user pauses printing, any print jobs that are pending are held in a queue until they either cancel them or resume printing. Click Resume to start printing again after it has been paused. Click Cancel All to delete all pending print jobs. To manage print jobs individually, click List all jobs. The webtop displays a list of all the print jobs the user has in the queue, along with information about the job, for example the number of copies and the printer that will be used. If you have paused printing, click to print just that one print job. To cancel a print job, click .

When printing from a Windows 2000/2003 or UNIX application server, users can choose which printer they print to. If the user does not select a printer, the output will go to their default printer. For all other application servers, the output always goes to the client device's default printer.

User's can see which printer is their default printer by pointing to the printer icon on their webtop. A popup displays the name of the default printer.

If a user wants to change their default printer, they must log out of Secure Global Desktop, change the default printer and then log in to again.

How Secure Global Desktop Administrators control Secure Global Desktop print services

Secure Global Desktop Administrators control printing services with the tarantella print command. This command lets you:

List spooled print jobs and identify the Secure Global Desktop users they belong to. You can use this to check that print jobs from the application server printing system have reached the Secure Global Desktop print queue.
Remove print jobs from the Secure Global Desktop print queue.
Pause and restart Secure Global Desktop printing services.
Move print jobs from one Secure Global Desktop server to another.

How do I set up Secure Global Desktop printing?

To set up Secure Global Desktop printing you need to:

Configure your application servers:
Configure the Secure Global Desktop server to accept remote print requests.
Configure printing if you use the Common UNIX Printing System™ (CUPS).
Configure printing for UNIX clients.
Configure Secure Global Desktop PDF printing.
Configure Secure Global Desktop print job conversion.
Test that printing works. If you have trouble printing, follow the steps in the printing troubleshooter.

Depending on your printing requirements, you may not need to carry out all of these steps.

For Windows 2000/2003 application sessions you can configure the client printers that are available:

using the array-wide settings on the Printing properties panel in Array Manager.
using the Printing panel for organization, organizational unit or person objects in Object Manager.
