(✽) • Any data in the buffer is lost when the printer power is
turned off.
• When the printer recovers from an error using DLE
ENQ 1 with cut sheet mode selected, the printer
ejects the cut sheet and then executes loading. When
the printer recovers from a cut sheet ejection error,
the printer checks for paper ejection but does not
execute loading.
• When the printer recovers from an error using DLE
ENQ 2 with cut sheet mode selected, the printer
checks to make sure that the remaining paper is
removed and then enters paper roll mode.
