Dear All, I wish to send printer code to epson lq 590 to print the
barcode using the printer built-in barcode font. How would I do that
in report ?

Thanks.

Never used this myself, but a Field has two properties called "Printer
Code Before" and "Printer Code After".

I think you push the escape sequences of the printer into them.

So, for example, if <ESC>[F3 turns on font 3 (that's a made up sequence,
and also I am pretending 3 is the barcode font), then put those 4 bytes
into "Before". Then those bytes are send just before the value is sent
and the value will print in the barcode font.

How to get the escape sequence? Perhaps as follows: Read the printer
manual (the easy part). Then use some editor that allows you to control
what bytes you use. Then cut and paste that string into the property.

If your editor doesn't give you that kind of control, then perhaps
something like perl -e "print chr(27),chr(1),chr(2)" > temp.tmp, then use
notepad to open that file and cut/paste the contents into the field.

-- All guess work, having never done this myself. --

I've tried using the printer code from the epson manual and create a
prt file, I can get the output to be set to bold or italic, however it
is can get the barcode printed. May be using barcode true type font in
Oracle Report is the better way, rather then using the manufacturer
printer code....
