Spanish Imprimir tiquete desde b4a en impresora Bluetooth portatil

jmorales · Jul 3, 2015

Muy buenos dias, ante todo gracias por su tiempo

Estamos desarrollando un programa de toma de pedidos en b4a y necesitamos imprimir el pedido o tiquete, la aplicacion trabaja desconectada y es muy posible que al momento de imprimir NO se tenga internet.

Si me pudieran ayudar con dos cosas porque puedo escoger el modelo a usar

1. Alguna printer que me recomienden que no de muchos problemas.

2. Me pueden recomentar alguna libreria, que no dependa de tener internet.

Muchas gracias y saludos desde Costa Rica

Hola, yo te recomendaría que uses pdfjet, es una librería con la que puedes crear archarchivos pdf al tamaño que quieras, una vez creado el pdf cada marca de impresora suele tener su propia app en el market para imprimir, seleccionas el pdf creado y listo, una vez que controlas pdfjet resulta mucho más fácil que intentar imprimir en la impresora directamente.

Muchas Gracias dar2o3 lo voy a probar, pero tengo una duda, yo armo el archivo pdf en eso estoy claro pero puedo desde la aplicacion mandarlo a imprimir ? algo parecido a un shell o como ?

Muy buen dia

No estoy en casa y escribo desde el móvil pero te dejo el Link, bajate el ejemplo y ahí puedes ver como abrir el pdf desde la aplicación una vez creado.

AYUDA, quien puede ayudarme, tengo una aplicación para facturar. El problema es que en algunas ocasiones la impresión del ticket sale desordenada. por ejemplo se imprime en la primer linea el monto facturado, y luego salen los encabezados, pero en otras ocasiones sale bien. les dejo aqui el código que uso

Te paso el código que yo uso para los autoventas y que funciona bien normalmente los autoventas usan una impresora start matricial ya que permite papel con copias en el veras que hay comandos diferentes si es para una start o otra impresora que no sea matricial
