Memory, Flash Cards, Font Cards
Zebra printers come with a variety of memory options. These include
DRAM, EPROM, PCMCIA, FLASH, SOCKET FLASH and
BATTERY BACKED-UP RAM. Depending on which printer model
you have, on most Zebra printers you can print out a Printer Configu-
ration Label which will show the letter designation(s) assigned to your
printer memory. Some printer models do not support this feature,
however, so the following chart should help you in determining how
the memory IDs are assigned (memory IDs default to these values
when the printer is reset to factory defaults):
EPROM E:
PCMCIA B:
FLASH E:
DRAM R:
BATTERY BACKED-UP RAM B: or E:
SOCKET FLASH B:
NOTE: Not all memory options are available on all printers
There are a few ZPL II commands that directly affect the types of
memory available to Zebra printers. They are ~JB, ^JB and ~HM.
The ~JB (Reset Battery Dead) instruction is used for the following two
conditions.
1. This instruction must be sent to the printer if the battery
supplying power to the Battery Powered Font Card fails and is
replaced. (A bad battery would show a “battery dead” condition
on the Printer Configuration Label.)
NOTE: If the battery is replaced and this instruction is not sent to
the printer, the Battery Powered Font Card will not function.
2. To intentionally clear (reinitialize) the Battery Powered
Font Card.
The ^JB (Initialize Flash Memory) instruction is used to initialize the
two types of Flash Memory available in the Zebra printers.
