5.3 Host Port Initialization

A/C-7P RO, A/C-7S RO

PC printing longer than 10 to 20 minutes (depending on host configuration) may cause the 3270 host to drop communication with the printer (“go to sleep”).

The output protocol specified in the A/C-7S RO’s configuration (through configuration-switch settings) is irrelevant for printing from the shared port. For PC/LAN printing, select the appropriate printer driver on the PC/LAN printer server.

5.2Parallel/Serial-Port Initialization

If you want to change the printer’s configuration for shared printing (e.g. set it to PostScript mode), use the parallel- or serial-port initialization string (Host/PC download command 56 for parallel; command 58 for serial). Consult the printer’s user’s guide for the ASCII hex values representing the desired configuration commands. Then store these commands in the A/C-7 RO’s memory using Host/PC download commands 56 or 58.

After the host printing is completed and before the print job from the shared port is sent to the printer, the A/C-7 RO will send this initialization string to the printer and configure it according to your instructions. However, it is possible that the print job coming through the parallel or serial shared port contains other printer instructions, thus overriding the parallel initialization string.

5.3 Host Port Initialization

After shared printing, the A/C-7 RO reconfigures the printer according to the active configuration settings. If you want to further modify the printer configuration (e.g select a different font for all host printing) take advantage of the host port initialization string. Unlike the parallel- or serial-port initialization string, which is usually overridden by commands coming with the PC/LAN print job, the host-port initialization string is not sent to the printer until after the A/C-7 RO has reconfigured the printer for host printing. The initialization string is sent at the beginning of each printed page.

5.4 Print Position and Page Length

Table 5-1outlines the PMPP (Physical Maximum Print Position) and PMPL (Physical Maximum Page Length) for letter, legal, and A4 size paper.
