Nv Graphics Printing; Esc/Pos Command - Epson TM-P60 Technical Reference Manual

• ID definition for developer or POS system
Note the following when writing to and erasing NV memory.
❏ The following restrictions apply when performing NV memory operations (including data
writing and erasing).
• The paper FEED button must not be used to feed paper.
• The real-time command must not be executed.
• The ASB status will not be sent, even when the ASB function is set to enabled.
❏ The printer sometimes enters the Busy state while data is written to NV memory. It is
important not to send data from the host computer while the printer is in the Busy state, as it
will be incapable of processing any received data.
❏ Frequent use of the functions for writing to and erasing data from NV memory can damage
the memory. As a rule in using the various commands, avoid writing to NV memory more
than 10 times per day.

4.6 NV Graphics Printing

This printer has an "NV Bit-Graphics" Function. This function provides printing Graphics (e.g. a
shop logo.) This function is available for ESC/POS control method.
EPSON provides a utility, "TMFLogo," that enables registration of a bitmap image in the NV
memory of an EPSON TM series printer. The bitmap image in the NV memory can be printed
with the printer by using each control method.
Printable Size
<width>
Paper width, or
less than paper width.
<height>
1200dot (normal mode)
2400dot (double-height mode)
Note
NV graphics data shares the domain used by user NV memory record data; therefore, the entire capacity of
the domain to which NV graphics data and user NV memory data are defined is targeted. The TM-P60's
entire capacity is 384 KB.
Example: The NV memory can store 64 items graphics data when the file size of a graphic is 6 KB.
