Printing Multiple Labels On The Same Line

Printing more than one label on the same line involves no more than

positioning the cursor and sending the data for each label to be printed. Since

the termination of the bar code data sequence (signalled by an upper-case Z)

causes the bar code to be printed and a carriage return to be executed, all of

the label information must be sent in the same escape sequence. The

following example shows an escape sequence used to print three labels on a

single line:

ESC*z5c<label1>z20c<label2>z35c<label3>Z

ESC*z5c Moves cursor to column 5

<label1> Bar code data

z20c Moves cursor to column 20

<label2> Bar code data

z35c Moves cursor to column 35

<label3> Bar code data

Z Initiates printing

Printing Bar Codes With Text

When printing bar codes with text, since the printer automatically generates a

carriage return and line feed at the end of the terminating character (upper

case Z), potential problems exist. As a general rule, for each line of bar code

mixed with text, send the text information first, followed by a carriage return

without a line feed (ASCII 13), and then overlay the bar code. (The carriage

return is required so that the bar code cursor position will be correct.) The

following example illustrates how to print text and bar codes on the same line.

This example involves a three-line bar code (and three escape sequences) as

shown below:

ESC*z0v25c1q<12345>Z

ESC*z0v Selects Code 3 of 9

25c Moves cursor to column 25

1q Specifies header placement above label

<12345> Bar code data

Z Enables printing this portion of the bar code

ESC*z75CThis is textCRESC*z0q25c<12345>Z

ESC*z75C Moves cursor to column 75

This is text Text for right of bar code

CR Carriage return without a line feed

ESC*z0q Disables header for this portion

25c Moves cursor to column 25

<12345> Bar code data

Z Initiates printing this portion

ESC*z25c0q<12345>Z

ESC*z25c Moves cursor to column 25

0q Disables header for lower portion

<12345> Bar code data

Z Initiates printing for lower portion of label
