Drivers for Thermal
Printers
The driver developed is
a graphics thermal printer driver for Windows
95/98/NT/2000/XP/CE, Linux (Red Hat, Mandrake)
and OLE Point of Sale devices. These drivers
support Serial, parallel and USB printers.
The Linux driver supports both CUPS and LPD
printing system. Compression algorithms were
developed according to the specifications.
The data is filtered before being sent to
spooler. The drivers are compatible with
various thermal printer models. Each model
may differ according to the Dot Size but
have similar escape sequences. Except for
the OPOS & JPOS platforms, a custom property
sheet was also added in the driver property
sheets to enable user to select various options
like compression, density, cutting, reverse
printing etc. It involved file and registry
handling as well as UI programming like adding
dialogues, components etc to the property
sheet.
DRIVER FOR 3DIMENSIONAL
MOUSE
Inspector is the name given
to this 3D mouse. We developed the Mouse
driver and configuration utility. Inspector
has the appearance of an ordinary mouse,
with an optical sensor placed underneath
and primary buttons placed on the front of
the device. The innovative and unique feature
is the relatively large orientation ball,
placed in the center of the device. This
ball offers 3D navigation in an easy and
intuitive fashion, and is unlike anything
on the market today. The Inspector is a USB
1.1 compatible product. It is constructed
as a two part composite device, where one
part handles the 2D mouse aspect of the product,
while the other handles the 3D orientation.
