Starting Slice Number (Dot Row #) - Microcom 424 Operator's Manual

Printer Commands
buffer is changed (ref. ^D94 command), the Starting Slice # is also changed
automatically to a value that is 67% of the new slice buffer size.
"XX" can be any integer value up to a maximum of the number of slices in the
Slice Buffer (See Table 5-14). If a value for "xx" is entered that is too large for
the print head, the printer will respond with the correct maximum value for the
head size currently in use.
Table 5-3 below lists the default Starting Slice Number for various heads and
buffer sizes. This command is used together with the ^D94 command to fully
set up the slice buffer function.

2.10" 640dot 300dpi
4.26"1280dot 300dpi
EXAMPLE:
Bytes/slice = 4" x (300 dots/inch) x (1 byte/8dots) = 150 bytes
So a Slice Buffer size of 192,000 bytes can store 192,000/150 = 1,280 slices.
At 300 slices/inch, the buffer can hold 1,280/300 = 4.267" of printing.
Default setting for "Starting Slice #" is 100 slices.
^A ^D Command
X 94 Set Slice Buffer Size:
2 88Kbytes
3 192Kbytes
4 256KBytes
5 320KBytes
6 384KBytes
This command sets the size of the slice buffer in increments of 64Kbytes. The
default size of the slice buffer is 88Kbytes.
NOTE: Any change to the slice buffer size will also automatically change the
starting slice to a default, which will be 67% of the new buffer size.
Because the printer can be fitted with a variety of different head widths and dot
densities, the actual number of slices that the buffer can hold will be
determined by the number of dots in the print head.
