ABSTRACT:
A printer of the type wrapping a master around a print drum and pressing a sheet against the master with the print drum or a press drum is disclosed. A pulse encoder is mounted on the press drum for sensing changes in the rotation speed of the press drum, so that a timing for feeding the leading edge of the sheet toward a clamper can be controlled. The clamper is capable of surely clamping the leading edge of a sheet and preventing it from rolling up. The sheet can be fed stably and reliably and can therefore be brought into accurate registration.
