CHAPTER 7: Twinax/Coax Configuration

c. Adjust MPP on CPI Change: IBM twinax and 3270-coax printers maintain

a Maximum Print Position (MPP) even when CPI changes. MPP normally

is associated with the CPI (10 CPI has a MPP of 132 associated with it, 15

CPI has a MPP of 198, and so on). Using this option will cause the print

server to adjust the twinax or 3270-coax printer’s MPP so that the

maximum amount of text can be printed on a line. For example, if you

had been printing at 10 CPI, the MPP would have been 132. If you then

change to 15 CPI part way through the line, the IBM twinax or 3270-coax

printer would not adjust the MPP but would start a new line when 132

characters had been printed. On an IBM printer, this would result in a

line wrapping in the wrong place followed by a short line. The entire page

would be thrown out of alignment, possibly even pushing a line or two

onto the next page which would in itself be a short page. The print server

will adjust the MPP so that the entire line is used, even though part of the

characters are compressed. The available options are No and Yes

(default).

d. Send LF for ESC J: ESC J is an ASCII command that can be used to move

the printing down in increments of x/216 inches. Since twinax printers

cannot do this, you have the option of simply ignoring such commands or

sending a line feed (LF) to the system printer every time the print server

receives an ESCJ command. The options are Yes and No (default).

e. Change CR to NL: Some ASCII jobs expect the printer to do a New Line

(NL) when a Carriage Return (CR) is received. A NL is defined as a CR

and a Line Feed (LF) which positions the cursor at the beginning of the

next line. With No selected, the print server will send a CR to the printer

when a CR is received from the ASCII host. A CR simply moves the cursor

to the beginning of the current line (but not the beginning of the next

line). The options are Yes and No (default).

f. Change LF to NL: Some ASCII jobs (primarily UNIX) expect the printer

to do a new line (NL) when a line feed (LF) is received. A NL is defined

as a carriage return (CR) and a LF which positions the cursor at the

beginning of the next line. With No selected, the print server will send a

LF to the printer when a LF is received from the ASCII host. A LF simply

moves the cursor to the next line (but not the beginning of the next line.

The options are Yes and No (default).

g. PC Support +5 Fix: With Yes selected, the interface will correct an error of

five print positions that can occur when printing from IBM PC Support

(now Client Access). The options are Yes and No (default).
