A/C-7P RO, A/C-7S RO

<data>: The data to be printed as a bar code. Some bar codes require a certain number of characters.

Others only allow alphanumeric or numeric characters. Before the A/C- 7 RO processes the data string, it will check the complete data string and verify that it is valid. This is why the ¬B at the end is so important. If an invalid data string has been entered, the A/C-7 RO will print “Invalid Data” in the place of the bar code.

NOTES

1. Valid values must be entered for each of the parameters specified above, even if the parameter is irrelevant for the type of bar code being printed.

2. If an invalid parameter value (other than invalid data) has been entered, the A/C-7 RO will process the bar-code command up to that point and then reject any information it receives after the incorrect value.

For example, a bar-code command string has been entered, however, an invalid <hr> value of 3 has been specified.

¬B2,6,6,3,0,0,code128_B

The A/C-7 RO would cause all characters after the invalid value 3 to be printed:

,0,0,code128

This helps quickly identify

where the mistake occurred.

3.Spaces in the bar-code command string are invalid and will lead to the same result as mentioned in Step

4.If invalid data (either too many characters or the wrong type of characters) is entered, the A/C-7 RO will print the error message: ** Invalid Data **

5.Allow for sufficient vertical spacing when printing text data beneath the bar code.

For example, when the bar code command sting is entered on line 1 of the document with a bar code height specified as 5 (approximately 1/2 inch or 3 lines at 6 LPI), and text is then entered on line 2 as follows,

¬B5,7,1,0,0,0,1234567890¬B This data overrun by barcode

this will cause the bar code to overlap the text in the second line:
