The ASCII background and graphics background

modes do not print labels immediately. Background
mode splits the printer memory into two segments:

the foreground and background memory buffers.

Data sent via background mode resides in the
background buffer and prints when the next label

format containing foreground data reaches the
printer. Background data stays in memory until

intentionally cleared.

All label formats require a header line. The header

line precedes all other commands in the label

format, with the exception of the printer wake-up
string (if used).

NOTE: A few ASCII commands, such as the

QUERY

STATUS

command, replace the normal header line.

These cases are noted in their command descriptions.

Header line parameters are critical for proper

printing. For most ASCII label formats you can
"rough-in" header line values as follows:

Use ! for ASCII foreground printing.

Use 0 for the X starting position.

Use a dot time of 100 for an aspect ratio of 1:1 in

linear dot time mode.

Determine an approximate maxY value by

multiplying the label length (or desired label length,
for cutter equipped printers) by the print pitch and

then reducing the value by 10%. For dot times other

than 100, divide the result by the aspect ratio (dot
time divided by 100).
