Line Printers and Kernel

[Peter Wichert]

Hi folks !

We're using SCO Xenix 2.2 with parallel line printers .
There are two things we don't understand:

1.	The problem which occured is that the printer would not work as fast
	as possible .
	The printer is connected to the parallel port of the Hercules-Card.
	The spooler seems to work correctly.

	First we thought, that the terminal processes accessing the graphics
	card would slow down the supplement of the printer.
	But connecting the printer to a serial/parallel interface card had
	the same effect; also 'cat file > /dev/lp[0,1]' .

	The manual does not give us any hints.
	What's wrong ??


2.	What is the standard number of NBUF and SABUF ?
	Are there optimal values differing from the default values
	generated by the kernel during startup ?

	AND: what are SABUFs ??


Please reply directly to :

(If anyone is also interested in the answers, let us know. We'll forward
the useful ones .)
