INTERFACE CONFIGURATION
After installing the interface card and performing a self-test, the interface is ready
to operate in most environments. The factory default settings will be satisfactory
for most programs and applications. Be sure to check Command 60 on the self
test print out to confirm that the interface is configured correctly for either a dot
matrix or HP laser printer.
If you are using a laser printer, make sure you set your printer’s emulation mode
to match that of the interface: HP emulation or dot matrix emulation. (If your
laser printer supports Epson Job Language --EJL- commands, do not change the
printer’s emulation mode using the EJL command or the command-pass-thru
feature while this interface is installed. Also, you may not be able to change the
printer mode using the control panel.)
If your printer prints a warning message, the interface and printer emulations do
not match. Use your printer’s control panel to match the interface and printer
emulation settings.
Never select the PostScript
TM
printer mode while this interface is installed.
If the printer is a matrix printer, you must select character set ‘Code Page 850’ in
the setup of the printer. Refer to the printer’s User’s Guide to determine how to
select the character set by using either dip switches or the front panel.
If you
have selected HP LaserJet emulation, the ‘Roman 8’ character set is automatically
selected.
All configuration selections can be changed by simply embedding commands (as
defined in Appendix A) in a 3270 print job or print screen (hard copy) that is sent
to the printer. These are called Host Download Commands. If the embedded
command is sent correctly, the characters that create the command are not
printed. If the command is printed, then the interface did not recognize the
command because of a problem in the format of the command. Correct the
problem and send the command again. If you wish to confirm the active setup
selections for the printer, you can print a listing page by either performing a self
test (pressing and holding the top button for 2 seconds) or sending the ‘98,1’
command to the interface.
Unless the ‘99,6’ command is sent to save the active setup in non-volatile (NV)
memory, the configuration commands only change the active setup values and
are lost when the printer is turned off. By sending a ‘98,1’ command immediately
after turning on the printer, you can identify the selections that are stored in NV
memory of the interface.
