Printing in VISULOX

In the default VISULOX Portal setup printing is disabled.

Follow this guide to setup and enable printing in VISULOX Portal.

Requirements

The following packages are needed for printing in VISULOX:

CODE

dnf install cups

systemctl start cups 
systemctl enable cups

dnf install visulox-printing-4.2.0-1.el8.x86_64.rpm

Enable printer in Workspace

To display the list of current print jobs in the Workspace, use:

CODE

visulox config -name workspace.showPrinting.expand=enable

All print jobs are displayed here and can be paused, resumed and cancelled via the according buttons.

Check / enable printer device sharing for the client

Right click on the TCC-Client tray icon, select "Device Sharing..." and check "Printers":

Example setup with PDF Viewer

For a first test, the PDF-Viewer has been set as printer during installation.

Example test via shell:

CODE

lp /opt/visulox/setup/example/tiger.ps

(type lp must be /opt/tarantella/bin/lp)

For this test command, make sure that the following lines are not commented in /etc/ttaprinter.conf:

CODE

LPDEST=tta_pdfviewer export LPDEST #TTA_HOST=<hostname>
PATH=/opt/tarantella/bin:$PATH export PATH

Check status

Check the setup with the lpstat and visulox-portal print status command:

CODE

lpstat -p -d
printer tta_pdfviewer is idle.  enabled since Thu 07 Sep 2023 07:04:58 AM CEST
no system default destination

visulox-portal print status
<host.domain>:
 - Printing services available
 - Jobs spooled: 0

Troubleshooting

If print jobs are not shown in Workspace as expected, use the following command:

CODE

visulox-portal print cancel --all

Delete files in the spool folder:

CODE

rm -rf /opt/tarantella/var/spool/*

Then restart the services.
