[Function] | Sending status in real time | ||
[Code] |
| <10>H<04>H<n> | |
[Range] |
| 1 | ≤ n ≤ 4 |
[Outline] | Sends in real time the status specified by "n." | ||
|
| n = 1: Printer status | |
|
| n = 2: Status caused by an offline condition | |
|
| n = 3: Status caused by an error | |
|
| n = 4: Paper detector status | |
[Caution] | • Each status represents the current status. It is | ||
•The status is transferred without checking whether the host is ready to receive or busy.
•This command is executed even if the printer is in offline state,
•This command is dealed with when it is received.
•If another data string of <16>H<04>H<n> (1 ≤ n ≤ 4) is received, the printer acts the same way as with this command. Therefore, the user should be reminded of this fact.
[Example 1]
Suppose a command "ESC * m nL nH [d1 ... dk]," where d1 = <10>H, d2 = <04>H, d3 = <01>H.
•The DLE EOT n command cannot be interleaved into the code string of another command consisting of two bytes or more.
[Example 2]
If the printer sends DLE EOT 3 when the host has sent down to ESC 3 in its attempt to send ESC 3 n, the printer handles the ESC 3 as ESC 3 <10>H. Thus, the user should be cautious.
•If ASB (automatic status back) is enabled by GS a, it is necessary to discriminate between the status due to AS and the status due to this command.
