There is a simple Print string routine PRTSTR (and CRLF)
In fact, it is one long string with text ‘KIM’ and ‘ERR’ and a CR and LF. and six trailing Null ($) characters and X-OFF characters.
The Null characters are to let the slow mechanic Teletype machine handle the incoming characters.
And there is the X-OFF($13) character, which stops printing papertape on a teletype.

The code parts where PRTSTR and CRLF are called are:

The PRTSTR routine prints first six Null characters and depending on the X register value:
CRLF = $OD $0A $00 $00 $00 $00 $00 $00
KIM = $13 KIM $0D $0A $00 $00 $00 $00 $00 $00
ERR KIM = $13 ERR $13 KIM $00 $0D $0A $00 $00 $00 $00 $00 $00

What is happening here?

The KIM-1 monitor types out three strings.
X=07 types CRLF
X=0C type KIM CRLF (at startup)
X=11 type ERR KIM CRLF (when papertape loading ends in in error)
all with trailing 6x 00
KIM and ERR are both preceeded by a X-OFF($13) character, which stops printing papertape on a teletype.

The subroutine PRTSTR
– fetches a character from the table at offset in X
– prints the character via OUTCH
– decrements X, back one character in the table
– and loops until X = 0 and the string printed
