When I try to take print out of any of the available document like invoice/po/so ,the following error appears.
AttValue: " or ' expected, line 21, column 10
(<class 'lxml.etree.xmlsyntaxerror'="">, XMLSyntaxError(u'AttValue: " or \' expected, line 21, column 10',), <traceback object="" at="" 0xb4d0b374="">)
WHAT IS THE POSSIBLE REASON FOR THIS ERROR?
Could you post the content of your log file (openerp-server.log)
