Printing a Label Inverted 180 Degrees

The ^PO (Print Orientation) instruction inverts the label format 180

degrees. In essence, the label is printed upside down. For more infor-

mation, see the ^PO command on page .

Serialized Data

The ^SN (Serialization Data) instruction allows the printer to index

data fields by a selected increment or decrement value (i.e., make the

data fields increase or decrease by a specified value) each time a label

is printed. This can be performed on up to 100 to 150 fields in a given

format and can be performed on both alphanumeric and bar code

fields. A maximum of 12 of the right-most integers are subject to

indexing. The first integer found when scanning from right to left

starts the indexing portion of the data field.

If the alphanumeric field to be indexed ends with an alpha character,

the data will be scanned, character-by-character, from right to left

until a numeric character is encountered. Serialization will take place

using the value of the first number found. For more information, see

the ^SN command on page 314.

Variable Data

To increase throughput, you can set up a program that uses variable

data fields. Then, instead of formatting the whole label each time a

label is printed, the printer will have to format only the changed data

field. To use this capability, you must use the ^MC and ^FV instruc-

tions. For more information, see the ^MC command on page 285 and

the ^FV command on page 226.

Stored Formats

You can create formats and save them in volatile memory. A stored

format can then be recalled and merged with downloaded data to form

a complete label. This process saves transmission time but not format-

ting time. It is particularly useful if you are not working with an intel-

ligent input device.
