Print interval (serial)

XON / XOFF

During the preset wait delay the interface is not ready to receive. After expiry of the wait delay the RTS signal

(or XON) becomes active again and requests the subse- quent transmission.

The next interval begins upon receiving of <CR> or <CR + LF>. <LF> on its own is not accepted.

The report functions „Printer read/not ready“ are handled by this protocol if no handshake lines are connected (RS 232 C, RS 422 or RS 485).

This function only applies to the E version, interface II.

XON

is transmitted if the IPP 144-40 GE is ready to

 

receive.

XOFF

is transmitted if the IPP 144-40 GE is not ready

 

to receive (see above).

Note:

If the IPP 144-40 GE is not ready to receive, it transmits this character just once, not continuously.

No adjustments have to be made, this protocol always runs parallel to the hardware handshake.

Improved handshaking for pre-stored texts After receiving the control command <CR> the printer now sets RTS at „BUSY“ or the signal XOFF is transmitted. When the printing of pre-stored text is complete, RTS is reset or the signal XON is transmitted.

This handshake can be used to control the data transmission and prevent rapid text calls being lost or overwritten.

Note:

Without Handshake the following can occur, if the text calls are sent in too quickly:

Data input:

<Ctrl C> 1 <CR> <Ctrl C> 2 <CR> <Ctrl C> 3 <CR>

Actual Print-out:

Machine No. 3 2 3

pre-stored Text No. 1

just „2“ printed, Text No. 2 missing just „3“ printed, Text No. 3 missing
