Duplex printing problems.

J

Jason L

Hi, I have a client who wants a farily straightforward,
push-a-button way of merging data with a form, then
printing the form in a duplex manner. Since there is no
automated way of doing this in Word, I am using the
solution from Jonathan West/Microsoft, but I believe I am
missing something from my code or am just ignorant as to
what needs to be there. The form is just two pages, and
there will be around 40-60 people using this form across a
network. I already talked to the client about setting up
a duplicate printer, but he said that would be too much
trouble for the IT guys. Here is the code I have for
changing to duplex, yet I know more needs to be added. Any
help here would be greatly appreciated. If there is any
simpler way of doing this, please let me know. I don't
like using this much code that I really don't know how to
fix or look for problems when something goes wrong.

-TIA, Jason

I'm not sure I understand you situation exactly, but I handle duplex printing by using escape codes. I created a system for creating insurance policies. A policy consists of a combination of various forms, some of which are simplex and some duplex. The very first thing in every form is a print field code with the escape code for either simplex or duplex. With field codes on, it looks like this: {PRINT 27"&10S" \* MERGEFORMAT} for simplex and
{PRINT 27"&11S" \* MERGEFORMAT} for duplex. These are the escape codes for HP PCL5. Doing it this way, no additional code is needed to control the duplex printing.

To insert a print field code, choose Insert, Field and select Print.

Essentially I am wanting to have automated duplex
printing, and the code I am using is not working. I read
that what you are using works, but how do you find out the
escape codes for a printer, and do you just put the field
anywhere in the document to be printed?

Thanks, Stuart.

I am having a very difficult time finding the Lexmark
Optra S 2455's escape codes, though. If anyone out there
knows the escape codes or knows where to find them, please
post a response here or e-mail me.

Thanks.

Usually you can find them by searching the web or calling

the printer company. The codes have to be the very first
thing printed on the page for them to work. I usually put
them in the first page header. They are a very easy way
to control duplex printing and have the bonus that one
document can have parts that are duplex and parts that are
simplex. That's why I used them.
What kind of printers do you have? I think that most

laser printers that use PCL 5 will work with the codes in
my first message. One last thing, escape don't seem to
work with PCL 6 drivers.
