Configuring the Printer 2-15
M3. device Storage type. Use R (volatile RAM)
M4. buffer size Buffer size in 1/10K ranges. The following table lists the configured buffer sizes
and min-max values for your printer. The printer’s configuration is stored in non-
volatile RAM and saved when the printer is turned off. The maximum value for each
buffer is listed; however, the sum of all the buffers cannot exceed the maximum
available memory of the printer.
Buffer Range Default
Transmit .5K – 4K 10K
Receive 2K – 16K 40K
Image 16K – 114K 38.9K
Downld. Fonts 64K – 4096K 64K
Scalable Fonts 10K – 128K 64K
Formats 16K – 128K 16K
Internal cannot reallocate cannot reallocate
Note: For the scalable font buffer, specify 10 if you do not use the buffer. When
using the buffer, specify a minimum of 40. The larger the number you specify
for the image fuffer, the longer your fomats can be. As a rule of thumb, divide
the value you select by 100 and round up to the next whole number. That
number is the length in inches.
Example {I,M,I,R,1000 | }
Stores the image buffer in volatile RAM and allocates 100K for it.
Checking Current Buffer Sizes
Send a configuration upload packet to check the sizes of your current buffers. See
“Configuration Packet Header
” for more information. After you check your current buffer sizes
you can begin reallocating memory.
If you want to increase your image buffer and you will not be using downloaded fonts, add that
memory into your image buffer.
Example
{I,M,R,R,20 | Receive buffer 2K
M,T,R,10 | Transmit buffer 1 K
M,D,R,80 | Downloadable fonts buffer 8K
M,V,R,160 | Scalable fonts buffer 16K
M,I,R,1000 |} Image buffer 100K
Make sure memory is available before adding memory to a buffer. In the above example, if the
image buffer (M,I,R,1000) was defined before the downloadable fonts (M,D,R,80) and scalable
fonts buffers (M,V,R,160) were defined, an error would have occurred.
