1.9 Automatic Print Head Gap Adjustment (APTC)
The 9300/9400 automatically adjusts the gap between the print head and the platen for paper thickness when
paper is loaded. This function is usually called APTC (abbreviated from automatic paper thickness control). It
is useful for users who often change paper types.
The print head carriage has a pressure sensor on the card guide which faces the platen. When paper is loaded,
the card guide is first set to the widest gap, pressed against the platen over the paper, and then backed for the
proper gap. The gap can be also adjusted by the paper thickness indicator in manual mode (the indicator is
accessible at the left of the printer when the front cover is open).
1.10 Automatic Interface Switching
The 9300/9400 has two interfaces: Centronics parallel and RS-232C serial. The dual interface allows the user to
connect the printer to both a network environment and a PC environment at the same time. The printer will
automatically switch to the proper interface (parallel or serial) when an AUTO option is selected for the
<INTRFCE> item by the HARDWRE function in setup mode.
1.11 Printer Driver and DLMENU
The 9300/9400 is delivered with two floppy disks.
One floppy disk contains printer drivers for Windows 3.x and Windows 95. The printer driver is a control
program to be installed on the computer for controlling document printing on the user printer. This printer driver
allows the application programs to make the best use of the DL9300/9400's functions. The printer driver for
Windows 95 has the plug and play detection capability.
The other floppy disk contains the DLMENU. The DLMENU is a printer remote setup utility program which
controls printer features in setup mode from the computer display in place of the printer control panel. This
greatly releases the user from tedious operation of setting up the printer from the control panel.
