Hi Badara,

I started doing some testing with your Printer functions. It works fine execpt for WinDefPrn(). Works well with 98, 98SE and ME but not for 2000.
Did`nt check XP yet...

When I looked at Windows 2000 register HKEY_CURRENT_CONFIG,
System\CurrentControlSet\Control\Print\Printers has no value in Default
So it`s returning nothing. Thus not detecting the default printer.

I will check for XP tonight to see if there is any differences.

I also have another question. Is it possible, from the Windows register, to somehow detect what type of printer it correspond to.
ex.: Laser, InkJet, Dot Matrix or Thermal.

I closely examined the register and could not figure out if this information was present. But I tought it was hidden somewhere esle.

Regards,

Gilbert

Hi Badara,

Searching for My Printer did not give any result but...
I did some exhaustive testing using the default printer name and found out that the default when changed was found under

HKEY_CURRENT_USER
Software\Microsoft\Windows NT\Current Version\Windows
Device value correspond to the default printer.

I did many changes and found the default printer name at the same place every single time.

When I think of it, it make sense. Since the default printer is not define globaly (like Windows 98) but by active user it is normal to find it under CURRENT_USER.

I will do some testing under Windows 2000 as soon as I can and let you know about my finding.

Can you to confirm if I`m right or not.

Hi Gilbert,

Yesterday i seek in XP registry but not found, and today
you give me the right way !

I confirm this work under XP.

I shall put a new upgrade today in "Printer functions" thread.

Merci.

Regardes,

Ho Badara,

I did more research & testing today. What I fiind out on XP worked well on 2000 but not on XP. Still will search for an answer and let you know later on.

Hi Barada,

I did more searching, specialy in XP registers, and find out that there is two places were available printers can be found:

For two shared printers installed on a station running Windows 98:
HKEY_LOCAL_MACHINE\system\CurrentControlSet\COntrol\Print\Printers

and

For two shared printers installed on a station running Windows 2000:
HKEY_CURRENT_USER\Printers\Connections

Seems that shared printers from 98 technologie are stored elsewhere than for NT technologie. Is it possible for you to confirm my findings ?

Also discovered that under XP it is possible to retreive printers capabilities directly from the registers.

These capabilities are:

printBinNames Array of paper bins
printCollate Binary of collate type
printDuplexSupport Binary of type of duplex
printMaxResolutionSupported Binary of maximum resolution
printMediaSupported Array of paper sizes
printOrientationSupported Array of orientations

They can be found under:

For two shared printers installed on a station running Windows 98:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Print\Printers\<PRINTERNAME>\DsDriver

and

For two shared printers installed on a station running Windows 2000:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Print\Providers\LanMan Print Services\Servers\<SERVERNAME>\Printers<PRINTERNAME>\DsDriver

Is it also possible for you to confirm these findings ?

In the later <SERVERNAME> can be anything depending on wich server we are attached to. Is it possible, from the register, to retreive the server to wich a station is attached to ?

I also would like Antonio to get invole in this thread. It would be most helpfull.

Hi Badara,

I did more searching and found out that the printer capabilities available under 2000 and XP cannot be found anywhere in Windows 98.

Could you validate this ?

Hi Gilbert,

Sorry, i was not here these days.

I answer you today.

Hi Barada,

Yesterday, I was talking to one of my friend that is very familliar with API calls. Unfortenatly he doesnt work with FiveWin but he says that all printers informations are available trought API Calls.

He says that trying to retreive this information from the register is a difficult task and he strongly suggested to forget the Windows register.

So, after talking to him, I downloaded API Guide and start investigating. I found out that all available printers under Windows 98, ME, 20, XP etc. is effectively retreivable from a few API Calls.

The only problem is that API Calls are made though DLL32 Class and I`m not familiar with it yet. I started a new thread on this subject, but have no reply yet.

I will try out some testing and let you know as I move along.

Regards,
