User`s manual

You can override the PostScript-specified data transfer rate and, on the LaserWriter IIntx, the
handshake setting, by resetting the LaserWriter II switches that normally govern those
settings. This returns control over those printer settings to the switches, unless you reset them
again by sending a PostScript program. To reset a switch, move it to the opposite position, wait
30 seconds, and then return it to the desired position.

Checking the parameters
There are two methods of determining the current parameter settings for the LaserWriter II by
sending a PostScript program.
Short program
You can have the LaserWriter II print the Options number, as defined earlier, by sending this
program.
/Helvetica findfont 14 scalefont setfont
30 500 moveto
(The Options number for the 25-pin port is )show
statusdict begin 25 sccbatch 10 string cvs show
pop showpage
Note: To check the settings to be used in the Diablo emulation mode on the LaserWriter IInt,
substitute the word sccinteractive for sccbatch.
Long program
You can have the LaserWriter II print the data transfer rate, parity, handshake, data bits, and
stop bits by sending this program. If you have never changed the settings, it reports standard on
the line for data bits. In this case, standard means 7 data bits.
/Helvetica findfont 14 scalefont setfont
/cr{show 182 currentpoint 20 sub exch pop moveto}def
/tb{show 300 currentpoint exch pop moveto}def
/Which{5 -1 roll 4 exch sub -1 roll cr
3{pop}repeat}def
statusdict begin 25 sccbatch end 182 650 moveto
