Standard Syntax Guidelines
When creating MPCLII packets
✦ Begin each packet with a Start of Packet.
✦ End each packet with an End of Packet.
✦ Define no more than 100 fields in a format.
✦ Define all fields in the order you want to image/print
them. The printer does not print in field number order.
✦ Separate all parameters with a Parameter Separator.
✦ End each field with a Field Separator.
✦ Enter all information in CAPITAL letters, except words
or phrases within quotation marks.
✦ Include all parameters for a field unless documented as
optional.
✦ Define non-printable text fields immediately before the
field to which they apply.
✦ Define options immediately after the field to which they
apply.
✦ Multiple options can be used with most fields. Options
can be used in any combination except as noted with
each definition.
✦ Keep in mind that proportionally spaced fonts need
wider fields than monospaced fonts.
✦ Do not place a new line (return) or any other
non-printing character in a character string.
✦ Spaces are ignored, except within character strings.
✦ Use a tilde (~) followed by a 3-digit ASCII code in a
quoted string to send function codes or extended
characters or send the 8-bit ASCII code.
✦ Enter fields in numerical order.
