Budget check module (printing)

If this module is present in the workflow, the account balance or the positive budget amount of the user account is checked. This means it decides whether or not a print job can be started (so there is no interruption of a print job). Depending on where the module is used, it has slightly different effects on the process.

It makes sense to use the module directly before the Send print job module, since all information about the print job is already known by this point.

Especially for direct printing, it is useful to inform the user if the budget check fails and the print job cannot be printed.
