<p>PURPOSE:To obtain an excellent printing by controlling an electric conduction time to a thermal head. CONSTITUTION:The number of heating elements by which an electric current is to be simultaneously carried is counted (step 1). In accordance with the counted number, a conduction time TN is read from a table on which conduction times are previously determined (step 2). The conduction time TN is set to an electric conduction timer (step 3). When the electric conduction timer is turned ON, the application of conduction pulses is started (step 4). When the timer counts up to the time TN (step 5), the application of conduction pulses is completed (step 6).</p> |
