Codes (EPOS)
The EPOS codes that are supported by the POSjet
®
1500 Printer are listed in this section. TransAct Technologies,
Inc. has no control over how Epson extends or changes these control codes. TransAct Technologies, Inc. makes no
guarantees as to the operation of our printer when it replaces an Epson printer. The TM-U325D and EPOS
emulations are intended to make it as easy as possible to replace an Epson printer with a POSjet
®
1500 Printer.
The POSjet
®
1500 Printer provides two Epson emulations. The first emulation is as close as possible to the TM-
U325D Printer and tries to make the POSjet
®
1500 Printer a drop in replacement. However, when the POSjet
®
1500
Printer is in Epson TM-U325D emulation mode, it is subject to the same limitations as a TM-U325D Printer.
The second Epson emulation is EPOS mode. It extends and enhances the TM-U325D emulation to remove some of
the restrictions and give access to some of the POSjet
®
1500 Printer features not addressed by the TM-U325D. It is
intended that the standard Ithaca
®
PcOS emulation be used for new applications.
The following section lists all TM-U325D and EPOS commands that are processed. They are as close as possible to
Epson‘s definitions. The user must remember that the POSjet
®
1500 EPOS emulation, unlike the TM-U325D
emulation, is not designed as a drop in replacement for an Epson printer. The POSjet
®
1500 Printer is designed to
bring new and unique features and functionalities to a point-of-sale receipt printer. These features are not always
compatible with Epson printers. Not all features of POSjet
®
1500 Printers can be supported by EPOS. In particular,
the ability to print color graphics is not supported.
Differences between Epson TM U325D and POSjet
®
1500
In a few minor ways, the operation and programming POSjet
®
1500 is not identical to a TM-U325D.
Validation
The TM-U325D has a fixed validation depth, the POSjet
®
1500 has an adjustable validation depth. To assure
compatibility between the POSjet
®
1500 and the TM-U325D, you should set this depth to the default of 1.5 inches.
The POSjet
®
1500 loads validation forms differently than the TM-U325D. The POSjet
®
1500 checks form
alignment after a load and may reject the form and ask the operator to reload it
Manual Validation.
The TM-U325D can perform manual validation by pressing the FORM Button, inserting a form and them sending
data to the printer. The POSjet
®
1500 has an auto-journal mode that will allow the POSjet
®
1500 to repeat any
validation information on the receipt tape. In many ways, this is an improvement over the TM-U325D, however it is
different. This mode is configurable. It can be disabled, enabled, b command only, or on by default. How you set
this configuration will depend on how the POSjet
®
1500 is used in your application.
EPOS Deviations
Several differences exist between the POSjet
®
1500 and Epson printers. The POSjet
®
1500 Printer and TM-U325D
have fundamentally different print technology. The dot pitch and cell size of the printers will also vary. The
POSjet
®
1500 Printer tries to duplicate the TM-U325D functionality, but it is not always possible. For example, the
downloaded characters print smaller on a POSjet
®
1500 Printer than a TM-U325D.
