Dear Above Board user,
Quikbuf version 2.1, included with the latest release of the
Intel utility software, has two undocumented parameters that
may help you to fine tune Quikbuf to your hardware. Use
these parameters ONLY if Quikbuf is not printing at normal
speed.
The first parameter is "MC=xxx". MC specifies maximum
characters transmitted per clock tick, the xxx would be
replaced by a number dependent upon the configuration of
your system.
Next, the PB parameter. "PB=xxx" sets printer busy status
hold time. To adjust PB try values of + or - 50 to determine
which way the numbers need to go, then use + or - 16 to fine
tune. Some printers such as the HP LaserJet need smaller
values to improve performance. For these printers just try +
or - 16 for the PB value.
To adjust the MC parameter, try changing the number from the
default table for your system + or - 2 until an improvement
in printing speed is seen. You can use + or - 1 to fine
tune.
Here is an example of what your command line might look like
the first time you load Quikbuf2:
C:>QUIKBUF2 256 AT E P MC=25 PB=3500
Subsequent adjustments of the MC and PB parameters may be
done without rebooting your computer and without specifying
other command line parameters:
C:>QUIKBUF2 MC=23 PB=3450
Disregard the error 510 "can't set up more than one buffer"
message; this is expected.
Use these MC and PB default values to determine a practical
starting point from which to begin your adjustments.

These were found to be optimum values for various printers.
Your computer/ printer combination may require different values.
