APRINTERS - slow on some machines

[GriffMG]

Hi All,

I've just had a small problem - APRINTERS() is taking a very long time to process on some machines - about 20 seconds to a minute!

Anyone know how to speed it up? I only want the printer names.

Griff,

Are these local printers, or are they on the network? I suspect the latter. With local printers, APRINTERS() is instantaneous.

Hi Mike,

Some are local, some remote - some with pretty naff drivers too.

They are all good on some machines, even on the same network, and on some machines there is a delay.

It's just a bit irritating.

Griff,

It usually happens with network printers. I think VFP has to resolve the path to the network resource or something.

Maybe you could call APRINTERS only once and then store the information for use later. That way you only take the single hit.

Andy,

I am calling it just once, close to the beginning of the app (in fact it's the same on nearly all my apps - except the ones that don't need to print).

All I use it for is to ensure that any application specific 'default printer' actually exists at runtime.

This prevents problems when the user has specified a printer yesterday, which isn't there today.

Ta all

Griff,

Maybe an API call to get the printers would be quicker? I don't know... if it continues to be a problem maybe it's worth a look. Although that's probably all VFP is doing in the background when you call APRINTERS().

Something like EnumPrinters IN winspool.drv is what I'm speaking of. Good luck.

Thanks Andy,

I might try that
