Printer for QNX

Thanks for timely warning regarding online alarm printing on laser printer.
We had not realised that laser printer may not be usable at all for our
requirement.

Now I would like to understand what would be the situation if we offer an
inkjet printer for QNX instead of a laser printer. Will inkjet printer be
able to handle online alarms? Will escape sequences of dot-matrix printer
work with inkjet (HP or EPSON) printer?

Cheers,
Krupa

Hi,

We wish to use an A4-size Laser printer (HP - LJ1000 or
SAMSUNG-ML1215) with QNX 4.25. Our requirement is of online alarm printing

(text

printouts only). We have earlier user serial/parallel dot-matrix printers
for such requirements. With dot-matrix printers, we have tried ESC sequences

for

changing attributes like character size, font,etc… Will the same set of
commands also work for laser printer? Is it necessary to configure the
printer for Photon and then use it? What is the easiest method of
configuring a laser printer for text printing with QNX? Please help…

Thanks,
Krupa

Maybe. Most laser printers implement HP and Epson escape sequences. If
you used one of those on the dotmatrix, then you may have to make few
changes. Depending on how you want the output to look, you may have to
adjust the line spacing and line-wrap may be handled differently. Keep
in mind that you can’t print to the edges of the paper on a laser as you
can on a dot matrix.



To keep your source code unchanged, you may be able to any tweaking with
an add-on filter; that’s what we do and it works well.

So you need only to change printer and all will work!

Bear in mind that the laser printers always print an entire page at a
time, which may not be suitable for online alarms!

A good many inkjet printers are like Winmodems - they rely on

proprietary drivers. I have seen some that advertise HP and Epson
emulations, but I have no experience with them.

I am curious - why do you want to avoid dot matrix printers?

Client insists the use of inkjet/laser printer instead of dot-matrix. If we
tell them that we are unable to configure the same for QNX, they will make
us select another OS maybe Windows!. We have fair amount of experience with
QNX and want to offer the same. Hence I am trying to figure out a way of
using laser/inkjet printer with QNX…

And the client is always right
Maybe not always smart, though.
Maybe these thoughts will convince them of the wisdom of using a
dot-matrix
printer for the alarm printer:

Most sheet fed inkjet printers will also be page printers - like
the laser printer, they need that formfeed before they will start
printing. If
they don’t mind one alarm per page …
Many of the inkjet printers lately have a hidden print head, so even
if it did print, you couldn’t see it. The formfeed helps here … sort
of
The noise of the dot-matrix printing help alert the operators …

Now if it’s just a logging printer, and you don’t care about seeing the
text
right away, then almost anything will do. I think you really do need
something
that takes continuous forms and has the print head visible. Maybe a
paper tape
printer (heat sensitive, usually, not good for archives) with wide tape
(10 cm)
and an alpha char set? You would probably need to write a driver for it
or build
an interface card with a micro to buffer and translate command codes.
Keep talking at them. What is it they don’t like about dot matrix
printers?
They aren’t that hard to find.

My sympathies, and good luck!

There are lots of inkjet Printers which do what you want. We have had success
with HP und Epson ones. You have to be careful though. Some will work only
with windows. Some newer ones have less of the charakter oriented features
like only few fonttypes. On some models you cannot look at printed lines until
some number of following lines are printed. Maybe for that reason some printers
will eject the current page after a short idle time. Sometimes you don’t want that
for alarm protocols.
