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