It's just straight windows printing from any application. I install a
"virtual" printer (MS publisher Imagesetter) and set it to print to file
(c:\erefprint\stdref.ps normally). Users just select the printer in whatever
application they are using and Windows creates the postscript file. My
software kicks in when the file appears.
The problem is sending the postscript file to a different folder for each
user under terminal services. Once it's there I don't have a problem.

Whats the code you're using to print the documents?
I've used pdf creation utilities that allow pdf printing straight from the
application without the need to monitor an individual directory. That would
reduce the complexity of the print process.

Subject: [THIN] Adding printer ports at login?
I am busy deploying a self-made application to lots of doctors surgeries. It
involves using virtual postscript printers printing to file to make portable
documents that may be emailed and dumped to printers. A utility monitors the
relevant folder, capturing and processing the files. It all works well.
However, several surgeries use thin client (TS and Citrix) so the virtual
postscript printers need to print to a unique folder for each user. I tried
using SUBST to map a drive letter (L:) to a unique folder and set the
printer to print to L:\stdref.ps but that doesn't work properly. Clients map
L: as expected and the print queue seems happy with the L: mapping but it
will only work when somebody is logged on at the console and even then
everybody prints to the L: drive of the logged on user, not their own.
So, at the moment I'm creating individual printers for each user and setting
security options so that the printer is only visible to the user in
question. This works but will cause an administrative overhead in the future
as staff change and creating and configuring 40 identical printers gets
dull!
So, to the actual query! I can programmatically create printers at login
using RUNDLL32 PrintUI.Dll... but I can only print to ports that already
exist. Does anyone know of a way to programatically create "Print to file"
ports (like c:\users\user1\stdref.ps, c:\users\user2\stdref.ps etc) from a
script or an application called from a script? Also, is it possible to
change the security on printers from a script, as the newly created printers
assign permissions to "everybody" by default.
All suggestions welcome.
Angus
