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:
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.

shown below:
