[fa.info-vax] Tektronix emulation on QMS 1200 laser printer

info-vax@sri-kl (10/23/85)

From: Bob Paver <CP.PAVER@MCC.ARPA>

We've recently acquired the Tektronix 4014 emulation firmware for our
QMS 1200 laser printer.  I'm now trying to get output from SAS/GRAPH
to the laser printer.  I tell SAS/GRAPH that the device is a TEK4014
and I use the NOTERMINAL option which causes SAS/GRAPH to write the
Tek 'directives' into a file.

The file has 510 byte records and carriage return for a record attribute.

Our laser printer is hanging on a serial port, running at 9600 baud.

MY PROBLEM:

At various points in the plot, the laser printer leaves plot mode and I
get ASCII characters written at the left margin of the paper.  Then the
printer goes back into plot mode for a while only to drop out again.  I
suspect that something (terminal driver, laser printer, gremlin) is 
generating a CR which by definition turns off plot mode on a Tektronix
terminal.

I've experimented with different terminal widths, wrap/nowrap, and I've
even reblocked the 510 byte records down to 120, 70, 256, and so on.
Nothing seems to help.

I know little about terminal drivers on VMS, but do know that SAS/GRAPH
can drive a TEK4014 directly just fine.

Can anyone help me out?  Or point me to the right place to look for info?

Oh yes.  We're running VMS 3.7 and the laser printer is defined to be a 
spooled device.
