Answer 1

You can give dynamic report name using configuration, but it will apply when you print one report.

Below is the example to Print custom name in report.Create one field in ir.actions.report.xml, in which user can configure report name.

from openerp import models, fields
class IrActionsReportXml(models.Model):
    _inherit = 'ir.actions.report.xml'

    download_filename = fields.Char(
        'Download filename')

Now you need to create two files.

1. Report Controller

   from openerp import http
   from openerp.addons.mail.models import mail_template
   from openerp.addons.report.controllers.main import ReportController
   from openerp.addons.web.controllers.main import content_disposition
   
   
   class ReportController(ReportController):
       @http.route([
           '/report/<path:converter>/<reportname>',
           '/report/<path:converter>/<reportname>/<docids>',
       ])
       def report_routes(self, reportname, docids=None, converter=None, **data):
           response = super(ReportController, self).report_routes(
               reportname, docids=docids, converter=converter, **data)
           if docids:
               docids = [int(i) for i in docids.split(',')]
           report_xml = http.request.session.model('ir.actions.report.xml')
           report_ids = report_xml.search(
               [('report_name', '=', reportname)])
           for report in report_xml.browse(report_ids):
               if not report.download_filename:
                   continue
               objects = http.request.session.model(report.model)\
                   .browse(docids or [])
               generated_filename = mail_template.mako_template_env\
                   .from_string(report.download_filename)\
                   .render({
                       'objects': objects,
                       'o': objects[:1],
                       'object': objects[:1],
                       'ext': report.report_type.replace('qweb-', ''),
                   })
               response.headers['Content-Disposition'] = content_disposition(
                   generated_filename)
           return response
   
       @http.route(['/report/download'])
       def report_download(self, data, token):
           response = super(ReportController, self).report_download(data, token)
           # if we got another content disposition before, ditch the one added
           # by super()
           last_index = None
           for i in range(len(response.headers) - 1, -1, -1):
               if response.headers[i][0] == 'Content-Disposition':
                   if last_index:
                       response.headers.pop(last_index)
                   last_index = i
           return response
