STANDARD PRINTER COMMANDS

command). The specified dot time is

rounded down to the nearest step.

NOTE: Dot time values that result in

aspect ratios less than 0.8 may cause

poor print quality. Dot times under 100

automatically disable high speed

printing. Some printers only support

dot time 100. Refer to Table 1. Printer

Command Compatibility for more

information.

maxY

Specifies how many dot rows are

memory-mapped for each label max

Y must be large enough to map all

label components, but not so large

that it causes memory overflow or

label skipping.

numlbls

Sets the quantity of labels to be

printed by the label format. The

allowable range is 0 to 65535.

Comments 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
