Configuring the Printer 2-19
Example
{I,M,D,R,80 | Downloadable fonts 8K
M,I,R,3200 |} Image buffer 320K
Make sure memory is available before adding memory to a buffer. In the above example, if the
image buffer (M,I,R,3200) was defined before the downloadable fonts buffer (M,D,R,80), an error
would have occurred.
About Memory Buffers
Image Buffer Used to image the current format. The printers support two 4-
inch by 8-inch buffers. You can create an image up to 16 inches
long without reallocating memory. The image buffer is cleared
after a printer reset.
Use the formula below to calculate the approximate image buffer
size.
21K x Length (for 203 dpi) OR
46K x Length (for 300 dpi)
Length is the length of your label in inches.
203 DPI Example
21K x 25 = 525
(Multiply by 10 and round up to the next whole number if
necessary)
525K x 10 = 5250
Enter 5250 for your Image buffer.
300 DPI Example
46K x 26.75 = 1230.5
(Multiply by 10 and round up to the next whole number if
necessary)
1230.5 x 10 = 12305
Enter 12305 for your Image buffer.
Format Buffer 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 your format packet including
the format header and all the options.
The result of the above calculation is in kilobytes. Formats
remain in memory when you turn off the printer.
Downloadable Fonts Buffer Used to store downloaded (bitmapped or TrueType) fonts. To
determine the size of your downloadable fonts, send a font
packet. For TrueType fonts, the file size, in bytes, is the
minimum amount needed in this buffer. See “Using the Font
Packet” for more information. Fonts stored in this buffer are
deleted when the printer is turned off. We recommend storing
downloaded fonts into flash memory.
