2,50 Sends <strong>the</strong> Drawer Kick-out Connector status.<br />
[Caution]<br />
• When <strong>the</strong> serial interface is used:<br />
For DTR/DSR control:<br />
The <strong>printer</strong> sends <strong>the</strong> status after verifying that <strong>the</strong> host is<br />
ready to receive. If <strong>the</strong> host is not ready to receive, <strong>the</strong><br />
<strong>printer</strong> waits for <strong>the</strong> host to become ready to receive.<br />
For XON/XOFF control:<br />
The <strong>printer</strong> sends <strong>the</strong> status without checking whe<strong>the</strong>r <strong>the</strong><br />
host is ready to receive or busy.<br />
• Because this command is executed when data is mapped in<br />
<strong>the</strong> receive buffer, <strong>the</strong>re may be a delay between receiving <strong>the</strong><br />
command and sending <strong>the</strong> status depending on <strong>the</strong> condition<br />
<strong>of</strong> <strong>the</strong> receive buffer.<br />
• If ASB (Automatic Status Back) is enabled by GS a, <strong>the</strong> host<br />
must discriminate between <strong>the</strong> status due to this command<br />
and <strong>the</strong> status due to ASB.<br />

Bits 2, 3: Whenever <strong>the</strong> Paper end Sensor detects a “paper out”<br />
state, <strong>the</strong> <strong>printer</strong> goes <strong><strong>of</strong>f</strong>line, and <strong>the</strong> command is<br />
not executed. The <strong>printer</strong>, <strong>the</strong>refore, never sends a<br />
status where bit 2 = “1” or bit 3 = “1”.<br />
