Secure Global Desktop allows users to 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 printing system on the Secure Global Desktop host and the native printing system on the application server.
When a user prints, the print job is sent from the application server to Secure Global Desktop server. The Secure Global Desktop server then sends the print job to the client, which sends it to the user's printer.
Secure Global Desktop uses distributed printing. Print jobs are always sent to the Secure Global Desktop server hosting the emulator session for the application. This means that a user's print jobs are distributed across the array, and there are no bottlenecks or single points of failure.
If the format of the print job used by the application server is different to the format needed by the client printer, Secure Global Desktop converts the print job before sending it to the client.
With PDF printing, users print from a Windows, UNIX or Linux application using a Secure Global Desktop PDF printer. The print job is sent from the application server to Secure Global Desktop where it is converted into a portable document format (PDF) file. Secure Global Desktop then sends the PDF file to a PDF viewer on the user's client device where the file can be viewed, saved and printed. PDF printing can be used to avoid issues with printer drivers and print job formats.
Users manage their own print jobs from the Printing area on the webtop:
When documents are printing, the webtop tells a user how many print jobs they have in the queue. Users can click Cancel All to delete all pending print jobs.
Users can also click Pause to temporarily stop printing. When printing is paused, any print jobs that are pending are held in a queue until the user either cancels them or resumes printing. Click Resume to start printing again. The printer icon changes to show you when printing is paused. 
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 Server, Windows Server 2003, UNIX or Linux 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.
Users can see which printer is their default printer by pointing with the mouse at 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.
Secure Global Desktop Administrators control printing services with the tarantella print command.
This command lets you:
To be able to print with Secure Global Desktop, you may have to do the following::
If you have trouble printing, follow the steps in the printing troubleshooter.
