Printer queues

On application servers use the /opt/tarantella/bin/scriptsprtinstall.en.sh script to create printer queues for each array member (!):

CODE

sh prtinstall.en.sh 

    [--ttahost SGD_hostname] 
    [--ttaprinter printer_name] 
    [--appprinter printer_name] 
    [--uninstall [printer_name]] 
    [--cups y | n | auto] 
    [--cupsconf filename] 
    [--cupscontrol filename] 
    [--gsbindir gs_bin_dir] 
    [--append] 
    [--help]

Default to use:

--ttahost	DNS name VISULOX Portal Server reachable from application server
--appprinter	Name of the printer queue on the application server (redirects the print file to tta_printer on VISULOX Portal
--append	Add new printer queues (not replace)

Define printer

/etc/cups/printers.conf:

CODE

<Printer tta_printer>
AuthInfoRequired none
Info tta_printer
DeviceURI ipp://<DeviceURI>:631/printers/tta_pdfviewer
Type 6
Accepting Yes
Shared No
JobSheets none none
QuotaPeriod 0
PageLimit 0
KLimit 0
OpPolicy default
ErrorPolicy stop-printer
</Printer>

Change DeviceURI (stop cups)

DeviceURI ipp://<DeviceURI>:631/printers/tta_pdfviewer

After login on the application server (VISULOX Portal session), the default printer is set to the right queue,
which points to the tta_printer queue on VISULOX Portal running the user's emulator session.
