If the default configuration does not include any active process, the PReS Workflow Configuration program
asks you whether to continue.
When the PReS Workflow Configuration program sends a configuration, the PReS Workflow service is
stopped and restarted, if it is currently running, and the new configuration starts being applied immediately.
If a file different from the default configuration file is currently opened, and if it includes unsaved
modifications, the PReS Workflow Configuration program asks you whether to save the configuration before
exiting. Select the Always save without prompting for confirmation option to automatically save any unsaved
work before exiting.
About Related Programs and Services
Services are programs that run in the background and automatically perform tasks that often do not require
any user interaction. With the exception of PReS Workflow Configuration, all the programs used by PReS
Workflow are run as service applications. PReS Workflow can thus use them as required without the need
for any user interaction.
Although you can manually start and stop any service running on your computer, most of the basic services
used by the system are started and stopped automatically. In the case of PReS Workflow and their related
services, you typically use a command included in your PReS Workflow Configuration program to start and
stop most services. Opening and closing your PReS Workflow Configuration program has no effect on these
services.
Available Input Services
Input services are used to pull in data files. The input services used by PReS Workflow are:
l LPD (Line Printer Daemon) Input service: Inputs data sent from an LPR client. The LPD/LPR
printing protocol is a common way to send print jobs that, in turn, use the TCP/IP protocol to
communicate through the network.
l PrintShop Mail Web Capture service: Monitors print requests from a PrintShop Web server.
l Serial Input service: Monitors a single serial port for incoming data. Note that all Serial input tasks
use the same serial port (set in the user options of the PReS Workflow Configuration program).
l Telnet Input service: Monitors multiple telnet ports for incoming data. Note that each Telnet input task
