Printronix T600 Administrator's Manual page 5

Note：
* Continuous printing will cause the printer motor to overheat. The printer will stop printing
automatically for about 10~15 minutes while the motor is cooling down. Do not turn the power
off when the printer pauses or the data transferred to the printer buffer will be lost.
* The maximum printing ratio per dot line is 15% for this printer. To print the full web black line,
the maximum black line height is limited to 40 dots, which is 5mm for 203 DPI resolution printer
and 3.3mm for 300 DPI resolution printers only, otherwise this may damage the power supply.
