monitor, start and stop PReS Workflow services (see "Users and configurations" on page284 and "The
PReS Workflow Service Console" on page727).
Services must use an account to be granted the permission to use the system’s resources and objects.
This information is included in the service's configuration and most services use the Local System
Account, which is granted access to all the system’s resources. All input and output services used by
PReS Workflow run under the same account. For more information on services and system per-
missions, refer to Windows documentation. For more information on how to configure the account used
by the services, see "Workflow Services" on page285.
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 com-
municate 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 pro-
gram).
l
Telnet Input service: Monitors multiple telnet ports for incoming data. Note that each Telnet
input task has its own telnet port number (set in each task).
l
HTTP/SOAP Server service: Monitors web pages and web sites as well as SOAP servers.
Available Output services
Output services are used to output jobs. The output services used by PReS Workflow are:
l
FTP Output service: Places output jobs on a server via the FTP protocol.
l
LPR (Line Printer Requester) Output service: Sends jobs to an LPD server or LPD compatible
printers. 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
PReS Image: Outputs jobs as PDF files or in a variety of image formats. You can also use PReS
Image to archive and/or email the files it creates. You can use PReS Search to search the PDF
files PReS Image creates. You can install multiple instances of the PReS Image service on your
network, and have PReS Workflow send jobs to one or more of these instances. Each instance of
PReS Image can generate PDFs or images and dispatch them from the host on which it runs.
