Merge lp:~andrei-levin/openerp-pos/openerp-pos into lp:openerp-pos

[Andrei Levin]

Added modules that gives possibility to print on a Fiscal Printer

[Yannick Vaucher @ Camptocamp (yvaucher-c2c)]

Please improve the description

Anything to do to setup the fiscol printer ?

review: Needs Fixing (description)

[Andrei Levin (andrei-levin)]

This module creates a base for printing to fiscal printer. It contains
all the functions that can be useful for creating a "driver" - a
simple module which contains functions that should be different for
various printer models.
The second module is a "dummy" driver that shows how to write a driver.

+This module creates all that is necessary to print on a Fiscal Printer.
+
+The solution is composed of 2 modules:
+- pos_fiscal_printer - a core module
+- pos_fp_<driver name> - driver module
+
+Core module:
+- disable printing from browser
+- create configuration menu inside POS
+- add departments
+- load driver
+- prepare all the data needed for creating a receipt
+
+Driver module:
+- compose a receipt
+- sent receipt to printer
+
+Menu Fiscal Printer gives you a possibility to match a Fiscal Printer
+to a POS. Very often Fiscal Printers has only program for Windows,
+which they call "Driver". This resident program expects to find a
+receipt file in some directory. When it finds a new receipt it is
+interpreted and send to a printer. We can't write to a file system
+directly from JavaScript, so Client start printing and then Server
+send a receipt to a computer which has fiscal printer attached.
+Sometimes we also need to wright a password for the Fiscal Printer
+inside receipt. This is the reason for 2 password fields.
+
+Another type of printers accept printing via ethernet. Again we need
+host/user/password.
+
+An ECR (Electronic Cash Register) should register a
+"department". Department depends on tax paid, so inside my Dummy
+driver you will see:
+reparto = line.product_id.taxes_id[0].department.department
+
+Core module creates Department table, which should be compiled (in
+Italy there are 3 main Departments: Reparto 1, Reparto 2, Reparto 3)
+with corresponding numbers. These numbers are used to tell ECR to
+which department a product belongs. After compiling the table, one
+should go to Accounting / Configuration and select a right department
+for the tax.
+
+There is another option which can sound strange - "Dry Run". When we
+print a receipt and something goes wrong, receipt will not disappear,
+every time we try to print it will be send to a Fiscal Printer, so if
+for any reason a receipt can't be printed it will block our POS until
+the problem is resolved (a red ball appears in the right upper angle
+of the POS). In this case one can select "Dry Run" option and when one
+enters POS the queue will be emptied and a red ball became green. This
+option can also be used if some receipts were printed directly from
+ECR and one want to register this selling without reprinting a
+receipt.
