M - Memory Card Access
cab printers are prepared for multiple possibilities if the built in or the optional memory is used.
The M commands (Memorycard -commands) are used for a couple of operations, described on the
next pages.
Following memory types are supported:
1. Internal Flash File system - called IFFS in the following text.
IFFS is not required for regular applications and has some restrictions. We recommend to use
Compact flash memory cards for the most applications and for the highest flexibility.
The restrictions are mainly all commands which try to write intothe memory, as the "E..." commands,
"[WLOG]" and "[WTMP]".
2. Compact flash cards - at the moment up to a theoretical maximum of 256 GB memory size.
3. PC Card - also called PCMCIA card memory, which might be SRAM or Flash memory
( Usage not recommmended, but helpful to transfer data from previous printers which used
that memory type.
4. USB MSD devices ( USB - Mass Storage Devices) such as the most „USB memory sticks“
(It is not possible to guarantee that all of the USB devices on the market will work properly.
Validation of good or bad quality USB sticks must be done by yourself).
Furthermore external harddisks can be connected which may require in the most cases external
power supplies. Maximum supported size is 2 TB. ( Maximum file size is 4 GB)
Please note that only FAT16 and FAT 32 filesystems are supported. NTFS, EXT2 or EXT3 etc. are not
supported. It is not recommended to format a huge harddisk in the printer, as the USB 1.1 port would
require incredible time to finish that.
Why use additional memory ?
Memory cards are normally used, if a printer runs in „Stand Alone Mode“. Data from memory cards can
be easily recalled or filled with variable data with an optional PC keyboard or barcode scanner, which
can be attached through the USB port of the printer.
Furthermore the optional cab database connector (later described in this manual) can be used to recall
fixed data from the memory card and connect additionally to the network to recall information from a
SQL database.
