CUPS-system on the computer for printing. It is designed for use on a Maemo 5 device.
You can print files in all formats supported by CUPS:
On the computer to which the printer is attached to, you need the cups and ssh-servers. CUPS (Common Unix Printing System) is a printing server, installed by default in several linux distributions. The ssh server is needed to safely connect to the computer. The port 22 needs to be opened from the computer's firewall. There is no need to open a port for cups.
The password is left empty. Remember where you have saved the keys! You cannot save them in the MyDocs folder, since the private key must not be accessible to others than the user.
The access rights of the file need to be set:
The public key is added to the server (computer) in the home folder's .ssh folder's file authorized_keys . You can use ssh for transferring it:
The location of the private key is set in the settings of URPO.
Host name or ip address: The computer's (server's) ip address, or its name if the device can find it by name.
Username: The user account on the server .
Identity file: The private ssh-key.
Choose the printer.
If desired, limit what pages are to be printed, e.g 1,2 or 3-6 or 1,5-7 .
You can choose 1, 2 or 4 pages to be printed per sheet.
You can print 1-99 copies.
Printing is started with the Print-button.
"Debug" is chosen from the menu, a debug window opens. Information useful in solving problems, such as the commands given to server trough ssh and their output, is printed on that window.
