About Memory Buffers
Transmit Buffer Used to send ENQ, job, and upload responses. This buffer must be
allocated as volatile (R) RAM.
Receive Buffer Used to save data received from the host before it is processed by
the printer. Changing this buffer size affects the amount of data the
printer can receive without using flow control. This buffer must be
allocated as volatile (R) RAM.
Image Buffer Used to image the current format. Use the formula below to
calculate the approximate image buffer size.
10K x Length
Length is the length of your label in inches.
10K x 10 = 100
Multiply by 10 and round up to the next whole number
Enter 1000 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.
Scalable (Vector)Fonts Buffer Used to image the scalable or downloaded (TrueType or bitmapped)
font characters. Increasing this buffer size allows more characters
to be saved in cache memory, so the characters do not have to be
re-built the next time they are printed. Use 10 if you are not using
scalable/TrueType fonts. This buffer must be allocated as volatile
(R) RAM.
The printer does not print the fonts if there is not enough memory in
this buffer to image them.
