If printing is done immediately after the paper is partially cut and torn off, the
top of the next print out may be distorted.
We recommend advancing the paper one line after cutting before printing.
If you are using a serial interface that has a slow data transmission speed,
streaks may appear in the printouts when you are printing graphics or gradated
text, which require large amounts of data.
USB interfaces may be susceptible to the effects of electromagnetic interference
from the host or environment.
If this is the case, try using a cable with ferrite cores on both ends, which are
very effective at eliminating EMI.
