8.7.5.2.3 Extern Text: variable length – Print out/Deleting the input buffer
There can be up to 32 <Extern Text> objects within a print job. For each object
you can define the number of wildcards and the offset separately. But nevertheless
all <Extern Text> objects within a print job will process the same received character
string. It is just a matter of the <Start symbol>, <End symbol>, the <Wildcards>
and the <Offset> settings which part of the received character string is used by
the <Extern Text: variable length> object.
The received serial data are stored in an input buffer. The size of this buffer is defined
by the <Extern Text: variable length> object that have the largest sum from
wildcards and offset.
There are 2 basic rules for using more than one <Extern Text: variable length>
object in a print job:
1. Basically it is possible to use different <Start symbols> and <End symbols>
for each <Extern Text: variable length> object created. However this
wouldn’t be advisable because only <Start symbol> and <End symbol>of
the last created <Extern Text: variable length> object will be used. If the
object is deleted, the <Start symbol> and <End symbol>of the object
created before the delete object will be used and so on. Therefore it is highly
recommended using the same <Start symbol> and <End symbol> for all
<Extern Text: variable length> objects within the same print job.
2. Using within the same print job several <Extern Text: variable length>
objects which have all the same <Start symbol> and <End symbol> offers
the possibility of controlling the content to be used of a character string by
wildcards and offset for each object separately.
The example is a print job with three <Extern Text: variable length> objects. Each
object has different settings for wildcards and offset. The <Start symbol> and
<End symbol> shall be the same for all three objects. The character string
xxxGabc123456Sxxx shall be transmitted.
The settings for each <Extern Text: variable length> object looks as follows:
Object 1:
Wildcards: XXXXXXX 7 wildcards
Offset: 2 2 offset
Sum of wildcards and offset: 9
Start symbol: G
End symbol: S
