Spooler and Forward Printing
Spooler
A spooler for saving print data and conducting background printing is implemented in the TM-DT software.
Even in systems where multiple print jobs are concentrated, an application system can be configured where
response is not impeded.
General printing applications finish transactions upon confirming the printing. Due to such waiting, response
times deteriorate in systems where multiple print jobs are concentrated. The spooler application stores print
data and immediately returns the printing results to the application. This allows the application to proceed to
the next operation without waiting for the current printing job to be completed.
