8–18 IBM Proprinter Emulation
Cancel
ASCII Code CAN
Hex Code 18
Dec Code 24
Purpose Clears the print buffer of all printable symbols since the last paper
motion command was received.
Discussion The CAN command cancels all printable characters sent to the printer
from the last paper motion command. If any attribute command is sent
before a CAN command, all data before the attribute command are
printed unless the attribute command is a Horizontal Tab command.
This command will cancel the double wide attribute if set by SO. No other
print attributes are affected. A Cancel command can occur at any place in the
datastream and is acted upon immediately.
Carriage Return
ASCII Code CR
Hex Code 0D
Dec Code 13
Purpose Returns the logical print head to the first character column (resets the
pointer to the first character position).
Discussion If this code is configured for CR = CR + LF, command CR is converted
to perform a carriage return and line feed function. Refer to the
subsection entitled “Line Feed,” page 8–38.
The CR = CR configuration causes the character position indicator to be
positioned at character column one. Subsequent printable data preceding a
paper motion command overstrikes previous printable data.
The CR code in Proprinter emulation cancels expanded (double wide) print
when set by code SO. A carriage return can occur at any place in the
datastream and is acted upon immediately.
