Hi Rafael:

2 months ago I had to use TCPDF to print barcode labels as the current
webERP library was not precise enough for our needs (we must specify the
width of the smallest vertical bar).

I'm not an expert (al all) in PDF creation and was quite trial and error,
but ended up with a simple code to read and maintain. I found really simple
t use the "space management" space we have for printing purposes, when to
add a page, etc) so I guess we'll end up with shorter code doing neater
things.

I will be happy to forward you the script (was too customized to be of any
use for the community), but maybe it can help you with some portions of
reusable code for the barcode part, If you think it can help, just let me
know and I'mm forward to you.

Many thanks for keep updating webERP in this field, which is much more
tricky than it looks.

Regards,
Ricard
