❏ 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.
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. 4.6.1 ESC/POS command See “ESC/POS Application Programming Guide“ about the method. 4.6.2 Tips for Visual Basic When programming with Visual Basic, limitations prevent data from 81h through 9Fh and from E0h through FEh from being sent as characters. Therefore, you may be not able to print a part of Page 0 (for example )in Visual Basic.

If you store the bitmap in NVRAM, it is not necessary to restore it unless the NV memory is deleted. Print Depends on each control method.
