I asked a week or two ago how an Apple LaserWriter Plus could be set to a
faster serial speed than 9600.  Nobody answered, but some information I
requested from Adobe told me how.  I printed the following program (note --
you'll need to add the CTRL-D at the end as the comment indicates).  Then
I edited /etc/printcap by changing "br#9600" to "br#19200" and the printer
works fine.  Actually I did it on two printers, the newer one belched out
"ioerror" about 3 times afterward as the spooler was trying to send the
banner page, and the older one returned a message " %%[ exitserver: permanent
state may be changed ]%%".  But the next file after changing /etc/printcap
printed fine.  This will not work on a non-plus LaserWriter, which supports
only 9600 if the switch is set to 9600.
