Zusammenfassung:	Operator controlled document gripper means is provided for gripping and holding a continuous web document closely downstream of the printing line of the printer so that a printed individual form can be torn away while the perforated tear line is located within the printer housing. The document gripper means includes a clamping edge on a gripper bar fixed on an access cover supported for rearward and forward sliding movement on the upper surface of the printer housing. The clamping edge is normally spaced from one face of the document to allow free passage of the document over the platen and through the printing station. With rearward sliding movement of the access cover by the operator, the clamping edge engages and presses the document against the platen to grip and hold the document while the perforated tear line is positioned closely adjacent the printing line.
