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. For example, if you send

{I,M,R,N,20 p M,T,N,60 p

...}

the printer ignores the entire packet, because the second line allocates 6K for the transmit buffer, and 4K is the maximum for that buffer. 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 8 inch label without receiving an error, until you change your format header or increase your image buffer.

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.
