In these examples, there are many more fonts and each font has its own code. OCRB
for example has code 4206. This number is important later on.
Creating output
When having problems getting the correct font, simplify the report and thereby the
output. This can be done by creating a straightforward report using select
sysdate from dual as the query and limiting the number of fonts. This will avoid
long runs and create much smaller output files.
The output file
The resulting PCL-file is a binary file but is reasonably readable in the VI editor. The
first small part and the end part is binary, but the middle part is readable and contains
data that can be interpreted.
Verifying the output file
The only interesting information is in the readable, middle part of the file. Find the text
(this is the text displayed in the reports output) and check out the part preceding the
text.
It looks like this:
....;SD1,14,2,0,3,10.34,5,0,6,0,7,4099;LB here is your text
In the example above, the font is selected with code 4099. For the Lexmark printer, this
is selecting Courier.
In one example, the font OCR-B (code 4206) was needed. The font did not come out
until that specific code was generated just before the selected text. It looks like this:
....;SD1,14,2,0,3,8.57,5,0,6,0,7,4206;LBThis is OCRB font....
Problems & answers
If the output file contains the correct code, but the font does not appear on the printer,
the printer probably does not have the font available. This will also occur if the code in
the output file (deduced from TFM file) is not the same as the one the printer is
