A control means reduces the change in a main scanning speed when going from one line to the next in a printer using an in-line print head. This may be accomplished by using division driving to drive the print elements so that the drive current is equal to or below a specified level, and/or determining the number of print element blocks per line and adjusting the main scanning speed on a per line basis for printing. This reduces the maximum drive current required to drive a printing operation without noticeably reducing the printing speed of the printer, and further effectively reduces printing irregularities associated with division driving of print elements. |
