Estimado Juanjo:
I have a lot of clients who have dotmatrix printers (ticket printer,
and cashdrawers). Sometimes their transactional volume is high so they
use preprinted forms.
When we try to print from a pdf (with fpdf), we get a bad and slow
imprint. (it's not useful, 'cause it's treated like an image)
i've been trying to design a printing service using jzebra (which is a
java applet , javascript interfaced, that can be used to sen RAW
commands to a printer). It's the only plugin i know, that allows a
webapp to print directly to a POS/label printer.
To be honest, i don't know where to begin. It seems to me that
developping this kind of service means a modification to the wole set
of fiche.php
(third party, invoices, etcetera....).
Do you mean you want a button to print the screen on a printer ?
I'm afraid i can't really help you for that because sending raw data to
a device from a php application is not a feature available "by design"
of PHP.
i've been taking a look to the webservices module, but i could barely
get information about the services (examples of the autentication part).
http://demo.dolibarr.org/webservices/
It occurs to me that provissionally i could create a webclient
including jzebra which sends requests to them webservices (example. to
print a certain invoice) and then use the menu editor to include this
client "transparently" in dolibarr.
web service of dolibarr are designed to ask dolibarr to execute silent
code to add, get or update a third party or an invoice.
If you want to do something else, you must build your own.
*new note:
'been examinig the printig system (printing models): i could generate
an html file. but how do i do, so the java applet does not load every
time?
maybe to write javascript which looks for a special frame name?
any help will be really appreciated.

Tengo muchos clientes que tienen impresoras matriciales. El volumen
transaccional es a veces elevado, y algunos tienen formas preimpresas.
Cuando se imprime desde los pdf, la impresión es de mala calidad y
demasiado lenta.
Ademas muchos usan impresoras POS y cajones portamonedas que es una
discusión que ya habíamos tenido.
He estado pensando en diseñar un servicio de impresión para jzebra
que es el único plugin que conozco hasta el momento que permite
comunicación RAW con las impresoras de los clientes.
Pero lo cierto es que no sé por donde empezar. un Servicio de esta
naturaleza implicaría una modificiación a todas las fichas (terceros,
presupuestos, facturas, pedidos, etc....).
He estado observando el modulo de webservices pero lastimosamente no
hay mucha información acerca de los servicios. sobretodo la parte de
autenticación.
http://demo.dolibarr.org/webservices/
Se me ocurre provisionalmente crear un cliente que incluya jzebra y
envie solicitudes al los webservices (p.ej el de imprimir una
factura) y luego utilizar el editor de menus para agregar un link a
este cliente.
La verdad es que me gustaría asesoría de vuestra parte, en la parte
de webservices, con consumo de créditos, para poder elaborar de forma
mas practica el diseño
Espero tu retroalimentación
