Configuring the Printer 2-17
Buffer Allocation Considerations
Keep these items in mind when allocating memory.
 Do not allocate more memory than what is available.
 Free memory from one buffer before you add it to another buffer.
 Reallocate all the buffers if you need to reallocate any buffer.
 Send all buffer (re)allocations in one packet. The printer evaluates each individual buffer
allocation separately. If one buffer allocation is invalid, the entire packet is invalid. If you
define a buffer size that exceeds the maximum value, an error occurs. However, no
information is lost.
 Whenever the printer accepts a memory configuration packet, it takes effect immediately,
causing a printer reset. Any information contained in the buffers is lost. Resend your
formats, batches, graphics, or fonts to the printer.
 If you remap your image buffer, make sure the length and width specified in your format
header are not too large for the current image buffer. In other words, if you remap for a
2 x 6 inch label, you cannot print a 2 x 10 inch label without receiving an error, until you
change your format header or increase your image buffer.
Memory Considerations with Downloaded TrueType Fonts
 The size of the TrueType font file, in bytes, is the minimum amount of memory you must
have available in the downloadable fonts buffer.
 The scalable (vector) fonts buffer is used to image the downloaded fonts (TrueType). If you
are using several downloaded TrueType fonts, you may need 100K or more in this buffer.
The printer does not print the fonts if there is not enough memory in the scalable (vector)
fonts buffer.
 To use large point sizes (greater than 60 point), you must reconfigure memory and increase
the size of the scalable (vector) fonts buffer.
Clearing Packets from Memory
You may want to remove packets from the printer to increase memory storage capacity or if the
formats/fonts are no longer needed. In some cases, turning the printer off may clear the
packets from memory. If not, send a format clear packet.
Syntax {header,packet#,action,device | }
1. header Identifies the packet. Options:
A Check Digit Scheme
F Format
G Graphic
W Font
2. packet# Identification number of the packet to clear (1 to 999) or font number (0 to 9999). 0
is for all fonts.
3. action Action. Enter C to clear the packet.
4. device Storage device. Options:
F Flash
R Volatile RAM
