PRINTER EMULATION SCREEN FOR THE
AST-5250 PRODUCT FAMILY
The printer emulation screen on the AST-5250 product line is
designed to help the user control the printer's environment.
Pages 6-18 of the AST-5251/11 Users Manual, part #000196-001
E defines each of the functions the emulation menu can
perform. The purpose of this bulletin is to clarify two of
the functions of the printer emulation screen.
1. (F7) allows you to select either a 10 or 15 characters-
per-inch printer format if the emulation printer is off-
line. (The host can override this user-selected
setting.) This function was implemented for users who
would be using an 80 column printer, and have their
printer defined on the host as a 5256. This function
would allow them to print in 15 characters-per-inch, to
obtain a full 132 columns on their local attached
printer. If the host sends any control sequence to
modify the character pitch, it will override the
emulation setting.
2. (F8) allows you to select either a 6 or 8 lines-per-inch
printer format if the emulation printer is off-line.
(The host can override this user-selected setting.)
This function was implemented for 5256 printer
emulation. On an IBM 5256, there is a switch to set the
lines from 6 to 8 lines per inch.
These two functions were mainly implemented for 5256 printer
control functions. Both of these functions can be
overridden by the host system and often are, especially when
the printer is defined as something other than 5256.
