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. The 9805

 

printer’s maximum image length is 4.0" x 6.0"

 

without reallocating memory. The 9820

 

printer supports two 4-inch by 6-inch image

 

buffers. You can create an image up to 12

 

inches long without reallocating memory. The

 

9830, 9835, 9840, and 9850 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, even if it is

 

stored in non-volatile RAM.

 

Use the formula below to calculate the

 

required image buffer size.

 

19.13K x Length

 

Length is the length of your label in inches.

Example

19.13K x 6 = 114.78K

 

(Multiply by 10 and round up.)

 

114.78K x 10 = 1147.8

 

1147.8 = 1150

 

Enter 1150 for your Image buffer.
