ABSTRACT:
An attachment is made to a roller printer that indicates to a user of the roller printer that it is tracking a straight line on a vertical surface. The attachment in the best mode is a spirit level so positioned that it indicates whether the printing roller of the roller printer is horizontally oriented in use. A protractor or other form of angle indicator may be used with a pivotable spirit level to aid the user of a roller printer in producing a pattern that extends inclined to the vertical.
