Printer Management

The default way of handling printout is to send it directly to the POS as a device proxy request. However, it is also possible to buffer printout in the core and then include that text in the authorization response, to allow the POS to merge the EFT voucher into the standard POS receipt to save paper. Not all POS systems support this feature, so it should always be made configurable.

It is also possible to tag print lines as being "journal" so that they can be stored rather than printed. Again, not all POS systems support this feature.
