Command Sets
Active position after printing a bar code is the same position as before printing bar code.
After printing bar code, appropriate positioning control commands, see “Positioning Controls” earlier in this section, must be sent to print additional barcode strings, text or graphics.
In the following examples, HPA Pn command positions the Active Position at column Pn , VPA Pn command positions the Active Position at line Pn.
1. Two barcodes Code 39 on the same line:
DECSBCA CSI 0;;;;;;;;’q
DECBAR(start) data DECBAR(stop) HPA Pn
DECBAR(start) data DECBAR(stop)
2. Two barcodes Code 39 one above the other:
DECSBCA CSI 0;;;;;;;;’q
DECBAR(start) data DECBAR(stop) VPA Pn
DECBAR(start) data DECBAR(stop)
