Density of Receipt Print Lines
When the receipt station prints high density print lines (graphics), it automatically slows
down to a rate slower than 902 lines per minute. High density print lines are defined as
lines with over 50% of the dots printing on the line (there are 576 total dot columns on the
print station).
Duty Cycle Restrictions (Printing Solid Blocks)
There are restrictions on the duty cycle because of the heat generated by the receipt
thermal print head when printing solid blocks (regardless of the length of the block in
relation to the print line). The restrictions are ambient temperature, the percentage of time
(measured against one minute) of continuous solid printing, and the amount of coverage.
Caution: When the duty cycle approches the limits shown in the table, the receipt print
head will heat up and shut down. This may damage the print head.
