9-2 Packet Reference Manual
Reducing Imaging Time
Imaging time is the time it takes the printer to image the data for the first label after the printer
receives the format and batch packet. There are several ways to reduce the imaging time: send
formats and configurations once, use a batch quantity of zero, or update batch fields.
♦ If the formats use the same check digit scheme, you only need to send the check digit scheme
once.
♦ Send formats once and use the batch update field to change information on the label. Using a
batch update field reduces the imaging time, because only the fields that change are imaged.
All other fields remain the same as the last queued batch.
♦ Use the batch quantity zero method when your application requires operator intervention to
enter data. While the operator is entering data, the previous field is sent with a batch quantity
of zero. The printer images the field, but does not print it. After the operator enters the data
for the last field, the batch quantity can be specified. The last remaining field is imaged, and
the label prints almost immediately.
To pre-image a label:
1. Send the format and a batch header in one file. The first time you send the batch header, use
the parameter N (new batch), and the parameter 0 for (zero quantity).
Example {B,1,N,0 | }
The printer images constant text, line, box, and graphic fields, but does not print them.
2. Input data for each field, and send it with a batch header using the parameter U (update) and
a quantity of zero. When the printer receives the data, it immediately images the field, but
does not print it.
Example {B,1,U,0 |
1,"RODGER DIST CTR" | }
{B,1,U,0 |
2,"8292" | }
At this time, the printer is imaging all associated fields, including fields that copy from
other fields.
3. Repeat step 2 for each field except the last one.
{B,1,U,0 |
3,"BROADWAY" | }
{B,1,U,0 |
4,"555 WEST OAK AVE." | }
4. For the last field, input data and send it with the quantity of labels you want printed. When the
printer receives input for the last field, it immediately prints the labels.
Example {B,1,U,10 |
5,"DAYTON, OHIO" | }
Increasing Throughput
Reducing the imaging time increases throughput. You can also increase the baud rate to increase
the transmission time and increase throughput. Make sure the communication settings at the
printer match those at the host. Using a baud rate of 19200 is almost twice as fast as 9600 baud.
Using a baud rate of 38400 is almost twice as fast as 19200 baud.
