Ink jet printing apparatus

An ink jet printing apparatus comprising:

• a printing head operable to emit ink onto a printing sheet, the printing head being moveable along a first direction;
• a sheet transporter operable to transport the printing sheet along a second direction perpendicular to the first direction;
• a head moving mechanism operable to reciprocally move the printing head along the first direction;
• and
• a controller which controls the sheet transporter and the head moving mechanism to execute a first printing mode of moving the printing head while holding the printing sheet in a first stationary position, moving the printing sheet to a second stationary position, and moving the printing head while holding the printing sheet in said second stationary position, said controller being operable to control the sheet transporter and the head moving mechanism to execute a second printing mode of moving the printing sheet while holding the printing head at a stationary position.
