A question was asked pertaining to what exactly are the different ASCII
levels when dealing with printer support levels?
The screen shows:
ASCII (Y/N): _
Line Printer (Y/N): _
ANSI Level 2 (Y/N): _
ANSI Level 3 (Y/N): _
Any explanation would be appreciated.

These apply to text printers only i.e. those that you just send a stream
of text to. Each level is a superset of the preceeding one, and basically
the levels are:
ASCII:
no escape sequences supported, no renditioning (i.e. bolding,
underlining, etc.) Example: old teletypes
Line Printer (ANSI level 1):
no escape sequences supported, renditioning done by overstriking
(implies backspace support.) Example: LP11
ANSI level 2:
escape sequences supported, renditioning done by escape sequences.
Example: LA75. In fact most modern dot matrix printers now fall into
this category.
ANSI level 3:
as level 2, but additionally has proportional font support.
Example: LN03. Probably all non-PDL laser printers are in this
category.
(PDL = Page Description Language, e.g PostScript, HP's PCL)
