or otherwise, including any implied warranty of merchant-ability or fitness for a particular
purpose.
THARO SYSTEMS shall not be responsible for the specific application to which any Products are applied,
including but not limited to compatibility with other equipment.
All statements, technical information and recommendations relating to THARO Products are based upon
tests believed to be reliable but do not constitute a guarantee or warranty.
THARO SYSTEMS SHALL NOT, UNDER ANY CIRCUMSTANCES WHATSOEVER, BE LIABLE TO
BUYER OR ANY OTHER PARTY FOR LOST PROFITS, DIMINUTION OF GOODWILL OR ANY OTHER
SPECIAL OR CONSEQUENTIAL DAMAGES WHATSOEVER WITH RESPECT TO ANY CLAIM
HEREUNDER. IN ADDITION, THARO SYSTEMS' LIABILITY FOR WARRANTY CLAIMS SHALL NOT,
IN ANY EVENT, EXCEED THE INVOICE PRICE OF THE PRODUCT CLAIMED DEFECTIVE, NOR
SHALL THARO SYSTEMS BE LIABLE FOR DELAYS IN REPLACEMENT OR REPAIR OF PRODUCTS
No salesperson, representative or agent of THARO SYSTEMS is authorized to make any guarantee,
warranty, or representation in addition to the foregoing warranty.

1. Product Description
General Information
The THARO H-426 and H-434 Printers are heavy duty, high performance thermal transfer/direct
thermal label Printers suitable for large volume printing requirements in industrial applications. With
robust metal outer casing and inner mechanism, the Printers are designed to be durable, tough and
reliable, even in the harshest environments.
The THARO H-426 features a printhead density of 8 dots/mm (203 dots/in) and a maximum print
length of 1270mm (50”). The THARO H-434 features a printhead density of 12 dots/mm (300
dots/in) and a maximum print length of 558.8mm (22”).
Both Printers provide high-speed performance of up to 6 inches per second with an 8” diameter label
roll and 450 meter length ribbon capacities for large volume throughput. The THARO H-426 and H-
434 feature a large, backlit LCD that is easy to read and is capable of displaying either text or
graphics, making operation easy. A Real-Time Clock for time and date stamping of labels is standard
on the H-426 and H-434. Also standard on the THARO H-426 and H-434 Printers is a Stripper
Sensor to sense the presence of printed labels. With the Stripper Sensor activated, application
software such as EASYLABEL®can operate the Printers in Peel-Off or Tear-Off modes.
The THARO H-426 and H-434 Printers provide internal memory for storing downloaded label formats,
graphics, and fonts. Data can be downloaded to this memory via the Printers’ serial interfaces.
Using this memory the Printers can be operated without being connected to a computer, which
represents a great advantage regarding their flexibility.
Accessories available for the THARO H-426 and H-434 Printers include a Cutter for ticket or receipt
printing applications and the Internal Rewind to be used with the standard Stripper Sensor in strip-
and-peel applications.
Printer Options
Internal Rewind
The Internal Rewind can be used with the Stripper Sensor to rewind the label liner when the Printer is
operating in strip-and-peel mode. Its unique design incorporates a maximum liner switch that will
stop the Printer from printing when the liner diameter exceeds 110mm (4.33”).
Cutter
The optional Cutter can be used to cut labels or tag stock up to a 10-mil thickness. Cutter options
include a choice of: cut after each label, cut after a specific quantity of labels or cut at the end of a
print job.
2MB FLASH memory module
The Printer has the ability to use internal Flash memory for storing downloaded label formats,
graphics and fonts. This option provides an additional 2MB of memory above and beyond the 2MB
that is standard in the Printer. This increases the available space for the storage of these files.
External Keyboard
The PS/2 Keyboard connector allows you to connect your Printer to any standard PS/2 Keyboard.
This will allow you to input variable data to a label format stored in Flash memory.
EASYLABEL®- Label Design Software for Windows
EASYLABEL®labeling software allows you to drive your Printer and create a full range of label formats
with a minimum of effort. EASYLABEL can be installed under Microsoft Windows® on IBM PCs and
compatibles. For further information about EASYLABEL, please contact your THARO Reseller.
