The cron (by default) every minute, updates the printing.printer and
printing.job records from the cups server. The field values rarely
change, so we can prevent many updates in database.
Also, writing on `printing_printer.server_id` triggers another update
on the printing.job records as the model has a stored related field.

* [FIX] Fixed the print_document method of report
The new API migration was made to @api.multi because of the "cr, uid,
ids" signature, but "ids" was the ids of the records to print here, not
the report's ids.
Also, the new API version of "get_pdf" get directly the ids of the
records to print in the standard module, not a recordset.
* [FIX] UI is now (un)blocked only when using qweb-pdf reports in standard addons
