3.11 Connection of printers via parallel interface

The 746.0010 VA Trace Analyzer has a parallel interface dedicated to connect ex-

ternal printers with parallel interfaces. The external printers are connected to the

printer connection 14

14 of the 746 VA Trace Analyzer by means of the cable delivered

with the printer (see Fig. 23).

Before connecting a printer to the printer connection 14

14, the 746 VA

Trace Analyzer must be switched off by means of mains switch 11

11.

With the 2.746.0010 VA Trace Analyzer the internal battery of the

instrument can be discharged after comparatively short time if certain

external printers are connected to the parallel printer interface 14

14. This

malfunction arises when the 746 VA Trace Analyzer is switched

off and the external printer remains switched on. Please mind

that certain printers are still in a stand-by mode when switched off and

thus show the faulty behavior also in the off-state. It is therefore

necessary in any case to separate the external printer from the mains.

To avoid battery discharge we recommend to do the following:

Interconnect the mains cables of the instruments concerned (incl.

external printer) to an ordinary socket board with a common mains

switch. A 615 Mains distributor with RFI filter available from Metrohm

as an option can be used also (this enables additional noise suppres-

sion).

The type of the printer is selected on dialog page "VA TRACE ANALYZER". The fol-

lowing printer drivers are available (see also section 5.3.1):

If you connect other printers, ensure that these emulate a printer mode supported

by the 746 VA Trace Analyzer. In some cases, a reset on the printer may be neces-

sary before the printer works properly (see printer manual).

With single sheet printers, graphical printouts (curves, screen) are cut

if they exceed the page. Therefore we recommend to use a printer

with endless paper and the operation with

Auto form feed = no
