When automatic configuration is run for 3812 and 3816 printers, the printers report as a 5219 Printer. The first time the printer is used, the iSeries™ server sends some commands to the printer that allow the system to distinguish between a 5219 Printer and a 3812 or 3816 SCS printer.
However, this happens after the open processing has been done for the first output to print. The first output to print can be direct output or a spooled file. This means, for the first output printed, the system treats the printer as a 5219 Printer. For example, this means there is no page rotation for that first printed output.
In order for the system to recognize a 3812 or 3816 SCS printer, the printer writer must complete processing. After the first output has been printed, and a new printer writer is started, the system recognizes the printer as a 3812 or 3816 SCS printer.
Once the system recognizes a printer as a 3812 or 3816 SCS, it remembers the true printer type until the printer device description is deleted.
