DTR (Data Terminal Ready) - A status signal used to provide information about the status
of the communication line connected to the DCE end of an RS-232 link. Used in
conjunction with DSR. Microcom Corporation does not use this signal.
Ethernet - A fast and capable serial interface used by many networks for connecting host
computers to various peripherals.
Fanfold media - Die-cut or tag media that is folded into stacks.
Flash memory - Memory that is used to store font, graphics and label formats for faster
access. This is a non-volatile type of memory, which means that the information stored in
the memory chip is retained even when the printer power is turned off. The 428M printers
use two FLASH memory chips: a CODE flash (256K x 16), and a FONT flash (4M x 16)
GND (Signal Ground) - The ground terminal of a power supply’s output, and all points that
connect to it. This is an essential signal in an RS-232 communication link that is used to
reduce noise spikes that can cause a receiver to misread logic levels. Signal also known as
SG and SGND.
Guillotine Cutter – A cutter that has a blade that cuts perpendicular to the media path.
This type of cutter can be setup to make “partial cuts” which leave a small piece of label
uncut in the center of the label. Not all Guillotine cutters can make partial cuts; a special
blade is required. Cuts paper weights in the range of 60 – 100 gm/m
2 .
LDS (Label Design Software) - This is the resident control software language that is used
to develop label formats and controls the full function of the printer.
LPD (Label Present Detector) - This sensor, when enabled, detects when media is
present. This sensor is also referred to as a LTS (Label Taken Sensor). This sensor is
typically a reflective type sensor that is normally mounted above the paper stock looking
down at the paper just past the print head.
Platen - Roller that is located below the print head, which the media rests upon. (See Drive
roller)
RI (Ring Indicator) – An RS-232 handshaking signal that is NOT used on the 428M
printers. RI would leave the printer on pin #9 of the RS-232 connector if it were used.
Rolled media - Media that has been rolled onto a core, typically cardboard in nature.
Rotary Cutter – A cutter that has multiple angled blades mounted to a shaft that cut media
by rotating the shaft. This cutter only cuts in one direction, and cannot make “partial cuts”.
The rotary cutter is typically used when heavy label stock must be cut because it has higher
cutting force than the Guillotine cutter. Cuts paper weights in the range of 60 – 200g/m
2 .
RS-232 - A popular and inexpensive asynchronous serial interface used for connecting host
computers to various peripherals.
