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 adding it to another buffer.
♦ Reallocate all the buffers if reallocating 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 a
defined buffer size 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 the formats,
batches, graphics, or fonts to the printer.
♦ When remapping the image buffer, make sure the length and width specified in the format
header are not too large for the current image buffer. For example, remapping for a
4 x 4 inch label and then printing a 4 x 6 inch label causes an error, until the format header is
changed or the image buffer is increased.
Memory Considerations w ith Dow nloaded TrueType Fonts
Save the fonts to flash memory for optimal performance with downloaded fonts. No memory
configuration packets are necessary since flash memory cannot be reallocated.
2-20 Packet Reference Manual
Used to store formats, batch data, and graphics. Use the following formula to
calculate the required format buffer size:
Linecount x 50/1024
Linecount is the number of lines in the format packet including the format
header and all the options.
The result of the above calculation is in kilobytes. Formats remain in memory
when the printer is turned off.
Used to store downloaded (bitmapped or TrueType) fonts. To determine the
size of the downloadable fonts, send a font packet. For TrueType fonts, the file
size, in bytes, is the minimum amount needed in this buffer. See
Font Packet" for more information. Fonts stored in this buffer are deleted
when the printer is turned off. Store downloaded fonts into flash memory.
