Chapter 5 Application Development Information Precautions when Developing Applications This section describes information that you should be aware of when developing systems and applications using this product. Paper Removal Standby Setting The “Paper Removal Standby” function feeds the printed paper to the position where it can be cut and then stops it. The next print job begins after you remove the paper. ( "Software Settings" on page 78 ) To use the printer with the Paper Removal Standby function enabled, the printer firmware must be Ver. 1.08 ESC/POS or later.
• When this function is enabled, the operation of the following peripheral devices connected to the printer may be stopped in addition to printing. Even in this case, operation can be resumed by removing the paper that is waiting to be removed. ∗ Customer display ∗ Handheld scanner ∗ Buzzer (built-in, external) ∗ Drawer • Be sure to enable the paper removal detector when using liner-free label paper. • Be sure to disable the paper removal detector when using plain thermal paper. • Backfeed is not performed when the paper removal detector is disabled. • To have the buzzer sound when the printer is waiting for paper removal, set it in “Paper removal standby:
frequency” under “Software Settings”. The above limitations do not apply in this case. ( "Software Settings" on page 78 ) • If using a drawer, the above limitations do not apply if the drawer is opened before executing printing. Power Supply SW Setting The “Power Supply SW Setting” function allows you to disable power on/off with the power button. ( "Software Settings" on page 78 ) If you want to turn off the printer without using the power button, it is recommended that you send the command to execute the power-off process to the printer before turning it off. This will save the latest maintenance counter values. The maintenance counter values are usually saved every two min- utes.
For more information about the command, see the ESC/POS Command Reference. 117 Power Supply SW Setting Description Enabled The power button is enabled and the printer can be turned on or off with the button. If the power is turned off by the breaker, turning on the breaker will also turn on the power of the printer. Disabled The power button is disabled. Use the breaker to turn the printer on and off.
