EPL Y Command

Use the serial port setup (Y) command to change the communications settings on the printer.

1. With the host computer set at the same communications settings as the printer, send the

command to change the printer to the desired settings. Note: the Y command does not

support setting the data flow control, use the Xon/Xoff setting.

2. Change the host computer settings to match the new printer settings.

Refer to the EPL Page Mode Programming Guide for more information about this command.

Resetting the Default Serial Port Parameters

Do the following to reset the communications parameters on the printer to the factory defaults
(serial communication settings are: 9600 baud, 8 bit word length, NO parity, 1 stop bit, and
DTR/XON/XOFF

data flow control).

1. Press and hold the feed button until the green status LED flashes once, waits a moment

and flashes twice, and then waits again before flashing three times (release
immediately).

2. While the status LED rapidly flashes amber and green, press the feed

button. Serial

communications between the printer and the host computer can be set by the ZPL ^SC
command or the EPL Y command.

Note •

Early models of Zebra

printers running the EPL programming

language had

9600

baud, NO

parity, 8 data bits, 1 stop bit and a HARDWARE and SOFTWARE (merged) data

control (essentially DTR/Xon/Xoff) as the default serial port settings. The Windows operating
system flow control setting was Hardware for most applications.
