Overview

The BarTender Print Scheduler Service is a Windows Service that manages BarTender print engines and intelligently assigns jobs to them while maximizing performance. 

This article will provide an overview of the Print schedulers functionality and role within the BarTender environment. 

Applicable to

BarTender 2019 and later

Information

BarTender Print Scheduler Service uses a single pool of print engines so that resources are used efficiently. The Print Scheduler service ensures that jobs printing to a specific printer will always come out of that printer in the order the requests were received. When documents contain embedded data that can change, such as serialized counters, they will be bound to a single print engine to ensure that they print in the correct order.

The BarTender Print Scheduler has three main functions:

1. Manage the print engines, which includes:
   1. Starting/stopping the print engines dynamically
   2. Opening/closing documents automatically
   3. Handling the printing process
2.  Automates print jobs through the use of BTXML Script
3. Runs BarTender designer as a service in the background without need for user input

Print Scheduler Process Using a BTXML Script

1. Receive BTXML script
2. Uses an open Print engine or opens a new print engine
3. Opens document and during print time will access:
   1. Files
   2. Databases
   3. Linked resources such as images
4. Processes data from BTXML 
5. Sends print job to the print queue
