7167 Owner’s Manual Chapter 6: Commands
November 2002 169
If the slip is selected, this command will attempt recovery from a slip motor or flip jam by
re-homing the print head and waiting for a slip to be inserted before restarting the print.
Other errors associated with the slip, such as cassette door open, can be recovered from
only by clearing the specific condition, such as closing the cassette door.
n = 2:
Recovers from an error after clearing the receive and print buffers. Print settings that are
normally preserved from line to line, such as character height and width, are still
preserved with this command. This sequence is ignored except when the printer is busy
due to an error condition.
If the slip was selected when the error occurred, the receipt becomes selected when the
buffers are cleared. When printing on the slip is to continue, the slip must be selected
again.
The same error recovery possibilities exist as for
n = 1.
n = 3:
Cancels the slip waiting status. This sequence is ignored except when the printer is
waiting for a slip to be inserted.
When slip waiting is canceled, the receive and print buffers are cleared and the receipt is
selected. When printing on the slip is to continue, the slip must be selected again.
Exampleusing the GS sequence:
MSComm1.Output = Chr$(&H1D) & Chr$(&H03) & Chr$(n)
Exceptions:
The command is ignored if
n is out of range
An application using the DLE sequence must send ENQ within 100 milliseconds of DLE or
the printer will misinterpret the DLE and execute a Clear Printer command. Avoid this
possibility by using the 1D 03 n sequence that is handled exactly the same as 10 05 n.
