Important notes on document processing
The document printer can process single documents, multiple documents and
passbooks. Optionally the document printing point can also be equipped with a
magnetic stripe reader (MSR).
The manual document feed is supported by an automatic document adjustment
on the right- hand side.
The positioning of the print characters can be programmed for any horizontal or
vertical position (reasured from document edge). For document positioning the
smallest basic step is 1/180 inch. The maximum paper rate is approx. 70 lines
per second for documents and passbooks.
If a document is present, the printer automatically initiates an insert. When the
first print or positioning command for a document is recognized, this will be trans-
ported on to the correct processing position. If the printer receives data and no
sheet is available at the document printing point, the user will be requested to
insert a sheet by means of the flashing green ’PAPER LED’ on the operating pa-
nel.
For application programming the selection of the horizontal leading edge is op-
tional. The difference is that leading blanks must be ignored for horizontal posi-
tioning on a document or passbook with the horizontal leading edge on the left,
while leading blanks corresponding to the physical width of the printing unit and
document must be taken into account in the case of the horizontal leading edge
on the right. As an alternative to the use of leading spaces, the left margin can
be set as required (ESC l (n)).
Where precise accuracy of positioning is required, the desired print position
should be reached using the least number of commands possible.
