Im using debian stable (wheezy), using crunchgbag distro. trying to work out this issue i have installed pyyaml using pip. The printing fails both with pyyaml from pip and python-yaml from debian repos.

Also here are some corrections to the install instructions:

You need to install also python-simplejson, it is not listed as dependency.

the adduser command is not working, you have to use useradd ( at least in debian).

Hello, after a while im back at looking at your library.

I have succesfully set up everything, and it almost working with openerp 7

However when printing the receipt from openerp i get the following error, in character encoding. The printing stops and it just prints a few lines, but it does print a little.

The character that stops the printing is an é

I get the foillowing error:

I have tried enabling the different encodings in the yaml config file, even enabling every encoding at the same time doesn't solve the problem.

I have installed proxyPos last version from master.

Hello,

Does this official Odoo app replace your module ?

https://www.odoo.com/apps/modules/9.0/hw_escpos/

Pasting here for reference!!

hi,
i'm having trouble for printing the third line and next lines (it's working normal for the first and second line), it's always getting error on simplejson parse error " TypeError: Expected string or buffer".
I'm wondering if you already knew about this issue, btw i'm using Ubuntu 13.04, Python 2.7.4, and my OpenErp server version is 7.0-20131031-002505

hi, is this project still active?
is this same from the posbox project or different?
can you print in different languages, like chinese, arabic, etc.?

I cannot print to my USB receipt printer. The info.error log shows the following:

Good day, do you have an .exe installer for windows 7.

proxypos odoo 8 compatibility

I have tried the update branch. Here is what I got:

1. The printer still prints at 44 charWidth. My paper size is 80x297mm which is roughly 55 charWidth. I tried changing the values but it is still the same.

2. Is there limitation to what the template can pull from OpenERP? I cant pull the company tagline which is "rml_header1" to be printed out.

3. "Change" value remains at 0.

4. Logo seems even worse after the new update.

I can provide a screenshot of my result if needed. Let me know.

I installed Proxypos on my client till. Started proxypos-server.
proxypos.proxypos - INFO - Listening on http://0.0.0.0:8069/

If I go to localhost:8069 on my client till should it tell me connected devices. At the moment I am getting
Error: 404 Not Found

Sorry, the requested URL 'http://localhost:8069/' caused an error:

Not found: '/

Should I be seeing something on this address? I know this is not my Odoo instanace but should I see connected devices etc..

I tried using this image from google:

http://jpgraph.net/download/manuals/chunkhtml/images/qr-code-small.png

Cant print out the logo properly.

It produces one line of image as per below:

I followed the documentation but as I restarted my server, OpenERP failed to start as it clashes with the ProxyPOS port. For some reason, they share the same port? I tried changing OpenERP port number to 8068 and OpenERP can start as expected but the print result is still unclear.

I am using Linux Mint 13 Maya with OpenERP v7. The printer I am using is Partner RP320.

Like to check. What if my POS is running on Windows XP instead of Linux Mint, how can I make this work? Any help? Thanks.

I cannot print to my serial port printer i got:

SerialException: Could not configure port: (22, 'Invalid argument')

when trying to send something to the printer.

Hello,
I'm trying to print from POS80mm based on EPSON (ESC/POS) Thermal printer standard, browser is running on Lubuntu, OpenERP installed at AWS EC2 Cloud server, but couldn't done succesfully not even from Windows browser: different browsers different bad presentation, will the Mint steps work the same on Lubuntu 14.04?

If its not the same, is there an easier way to print simply buying another printer ready for OpenERP7, which one?

Thanks!

When I try to start proxypos-server I always get this error at the end.

socket.error: [Errno 98] Address already in use.

When I kill the process that is blocking proxypos-server to start, It starts, but when trying to access by web browser it gives an error 404.
