Spooler Function The spooler function is a function used to temporarily store printing data received from the application in the TM-Intelligent to carry out background printings sequentially. (ePOS-Device Service Ver. 2.6 or later versions) TM-Intelligent return response data to the application the moment the printing data enters the spooler to make it possible for applications to proceed to the next process without waiting for a printing complete response. The application can use the job ID included in the response data to send an inquiry on the printing status. EPSON TMNet WebConfig is used to configure the spooler. Perform the following settings. For details, refer to the Technical Reference Guide for each TM-Intelligent printer.  Settings to enable the spooler  Print process retry settings Forwarding can be used to send a printing job to a different printer if the printer does not respond to retry processing. For details, refer to Forwarding(p.20). Example 1 Send print data A to a TM-Intelligent (ePOS-Device Service I/F) from the input terminal. 2 The TM-Intelligent will save the print data A to the spooler and will return response data to the input terminal. 3 The TM-Intelligent will retrieve the print data and issue a print command to another TM-Intelligent. 18

Spooler Function

The spooler function is a function used to temporarily store printing data received from the application in

the TM-Intelligent to carry out background printings sequentially. (ePOS-Device Service Ver. 2.6 or later

versions)

TM-Intelligent return response data to the application the moment the printing data enters the spooler to

make it possible for applications to proceed to the next process without waiting for a printing complete

response.

The application can use the job ID included in the response data to send an inquiry on the printing status.

EPSON TMNet WebConfig is used to configure the spooler.

Perform the following settings. For details, refer to the Technical Reference Guide for each TM-Intelligent

printer.



Settings to enable the spooler



Print process retry settings

Forwarding can be used to send a printing job to a different printer if the printer does not respond to retry

processing. For details, refer to

Forwarding(p.20)

Example

Send print data A to a TM-Intelligent (ePOS-Device Service I/F) from the input ter-

minal.

The TM-Intelligent will save the print data A to the spooler and will return response

data to the input terminal.

The TM-Intelligent will retrieve the print data and issue a print command to another

TM-Intelligent.
