- Connect printer to the supply voltage indicated by a cross on
the sticker. ( see pin assignment page 6)
- Establish appropriate data connection (cable description:
appendix D)
- Initiate a data transmission, e.g. hardcopy via message
display, or a PC
Function description
The printout is invented and right justified, which gives the correct order
after the paper has been torn off.
The IPP 144-40 GS starts the printing immediately after reception of <CR>.
The control characters <CR>, <LF> and <FF> are print triggering
characters. Unrecognized control characters are always ignored
(Characters used: appendix E).
If a larger amount of data (more than 100 lines) must be printed at the
same time, a socalled handshake controls the transmission. If the receive
buffer is almost full, the printer transmits the character XOFF and activates
the RTS line (neg. voltage). If the buffer contents are reduced, the printer
transmits the character XON and switches the RTS line back to passive.
This is also the case when:
- the printer door is open
- the printer is in menu mode
- the paper feed is empty
Pagination is possible via an internal line counter. At the end of a page the
printer adds 3 blank lines. The page length is adjustable (appendix E). The
character <FF> enables a form feed.
Configuration
The printer is adaptable to many different applications. the default settings
are appropriate for most of them.
The set parameters are permanently stored (requires no maintenance). To
avoid changing the menu parameters by accident, link jumper B,
accessible from the front. This jumper is not linked at delivery. Jumper A
must remain open all the times.
