7-108 Chapter 7: Programming Guide

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.

(Real Time Request to Printer—continued on the next page)

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.
