Function Documentation

ro_print_ack()

bool ro_print_ack

(

wimp_message *

m

)

Handle message_DATASAVE_ACK for the printing protocol.

Parameters

m	the message to handle

Returns

true if message successfully handled, false otherwise

We cheat here and, instead of giving Printers what it asked for (a copy of the file so it can poke us later via a broadcast of PrintTypeOdd), we give it a file that it can print itself without having to bother us further. For PostScript printers (type 0) we give it a PostScript file. Otherwise, we give it a PrintOut file.

This method has a couple of advantages:

• we can reuse this code for background printing (we simply ignore the PrintTypeOdd reply)
• there's no need to ensure all components of a page queued to be printed still exist when it reaches the top of the queue. (which reduces complexity a fair bit)
