RTC ZPL II Commands

RTC General Information

05/25/2005 47867L-001 Rev. A

The Set Mode/Language ^SL (see page 9) command is used to select the language the days of

the week and the months are printed in. This command also sets the printing mode, which can

S for START TIME or T for TIME NOW. In START TIME mode, the time printed on the

label is the time that is read from the Real Time Clock when the label formatting begins (when

the ^XA command is received by the printer). In TIME NOW mode, the time printed on the

label is the time that is read from the Real Time Clock when the label is placed in the queue to

be printed.

Time and Date Precision

The time and date placed in a label field is determined at the time the label bitmap is created by

the printer (start time mode). If a batch of labels is formatted, the date and time will be the

same for all labels in the batch. If the printer is paused during the printing process and remains

in that state for a period of time, when printing resumes, the time and date will still be the same

as when the batch was first started.

Note • As of V60.13.0.1 firmware, the ^CO command is now ignored.

Note • For versions prior to V60, if more precise time and date stamps are required on the

labels, the ^CO (Cache On) ZPL II command can be used to limit the memory available for

label bitmaps and thus reduce the number of labels containing the same time and date stamp.

To determine the value for the “b” parameter of the ^CO command, perform the steps shown

below:

Please cycle the printer/print engine power Off (

O) and On (l) to clear the memory before

performing the steps below.

1. Print a Memory Usage Label

(

^XA^WD*:*.*^XZ)

and note the following value:

Available RAM (in BYTES)

(A)

2. Print a Configuration Label and

note these values:

Printer “Print Width” (in DOTS)

(NOT the Label Width)

(B)

Label Length (in DOTS) (C)

3. Determine the desired maximum

number of queued labels with

the same Time and Date value.

(D)

Note • Increasing the number of queued labels will improve throughput performance, but

Real Time Clock values will be less accurate. Two is usually a good compromise.
