LASER CARDS FOR HP 4000 TWINAX AND COAX PRINTERS
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 interface 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 interface 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 2.
4. If invalid data (either too many characters or the wrong type of
characters) is entered, the interface 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 bar code
this will cause the bar code to overlap the text in the second line:
This data overrun by barcode
