thanks for this Article that work for dot matrix printer.in Epson LX 800 printer driver have no any option through which we can set custome paper size. but your application do this one. it safe us against customer which is far away from us and is in different continent 
thanks on this kind Anticipation.

I'm not sure what your problem is. I know you can run into problems with certain paper sizes on certain printers. AFAIK, the code I posted doesn't correctly check that a the paper size was added. We had to ask the printer manufacturer about it or maybe in documentation?
|
|
|
|
|
After I used it, my application that was printing throw exception - "Handle is invalid".
This same application was working prior to operation on this project.
Can some one help me please?
|
|
|
|
|
I'm not sure what your problem could be unless you just have the wrong name for the printer. I've seen that cause an invalid handle before.

Do you have these code in VB.net?
|
|
|
|

No, sorry I don't have it in VB.NET. I had to port some similar code from VB.NET and it wasn't too hard. Let me know if you run into any roadblocks porting to VB.NET.

I did the most obvios thing. Create a DLL of it. Wich can be referenced and called in vb.net.
Maybe a solution for you to.

It seems like when trying to add a custom size nothing happens. This would indicate that the printer does not allow this size, but I am trying to add a custom size that actually already existed in the list. I removed that size from the printersettings (using printers and faxes, etc..) and then I tried to add this size through this peace of code, but nothing is added to the list when I look at it.
Does anyone have any clues??
Thanks...

Ok, now I see that the new form that is created is added to "Forms" tab in "Printers and Faxes" - File - Server Properties. How can I get this form programmatically as:
DefaultPageSettings.PaperSize = "the form that was created under Server properties"??
|

Did anyone solve this problem?
I see the custom form under "Forms", but I don't see it under pager size when it goes to print it.
How can I use the custom forms to actually print?
Thanks,
Tom

Hi, I haven't tried your code yet, but I'm interested in what u said that, there is some paper dimension that a printer doesn't support.
Cos I have an application that adding a custom form to a spesific printer name, but in some printer, the form doesn't show. For example, I tried to add a 8.5 inch X 5.5 inch paper to Epson LQ-2180, It works.
If I look into the control panel->printers & faxes->server properties, my custom form show.
& if it also shows in my code:
dim pDoc as New PrintDocument
pDoc.PrinterSettings.PrinterName = "Epson LQ-2180"
For Each obj As PaperSize In pDoc.PrinterSettings.PaperSizes
cboForms.Items.Add(obj.PaperName)
Next
But if I add the same paper (8.5 x 5.5), for example to Canon BubbleJet, It doesn't work. I mean, it shows in the control panel->printers & faxes->server properties.
But it doesn't show in my code.
Could u give me some advice? Any help would be appreciated. Thx
Regards,

All that I know to say about this is that some printer drivers don't like certain paper sizes. I'm not sure how to tell. One obvious constraint might be printer width. If you try to add a paper size which is larger than your printer's width, the driver rejects the paper size. As you've noticed, you'll still be able to add the paper size and see it under the printer's list with control panel->printers & faxes->(click on printer)->file->server properties. But as far as I can tell, there is no way to force the printer to allow you to select a paper size it doesn't like.
Are you saying that you've added the paper size (8.5 x 5.5) to the Cannon BubbleJet in code or from the Printers & Faxes window? If you're adding from the Printers & Faxes window, be sure that you've clicked on the printer and that it's highlighted when you add the paper size.
BTW, if anyone knows how to query the driver & see what the maximum / minimum paper dimensions are, I would love to know how to do this. Thanks,
--Travis

Yes,i add the paper size (8.5 x 5.5) to the Cannon BubbleJet in code. My code works without errors, & it also shows in the paper sizes list in Printers & Faxes window.
But if I'm looping it using, ForEach PaperSize In PrinterSettings.PaperSizes, The new custom paper size, doesn't show.
I also realize, that It always works with dot matrix printer. I mean I could add my custom paper size, then when I'm looping it, it shows.
I've read that, some printers doesn't support custom paper size. Yeah, I would like to know too if there is a way to see the min/max dimensions supported by a printer. Thx 4 ur fast reply.

Alphonsus Eka

In regard to the BubbleJet printer, it sounds like the paper size may have been added to the system's overall list of available paper sizes, but not actually added to your BubbleJet printer's list of available paper sizes? I still have alot to learn in this area.
I'm not sure what to reccommend. If the printer won't accept the paper size, you'll have to ask the Manufacturer what to do about it. We have had a similar problem at work and finally got StarMicronics tech support department to send a different driver which supported our paper size. Man, they're one of the most difficult tech support depts ever!

yes, I think the paper size may have been added to the system's overall list of available paper sizes, but not added to my BubbleJet printer's list of available paper sizes.
Yeah, if u need a printer to use custom paper size, think you should contact the manufacturer, asking for driver to support the paper size.
I've just contacted by my manager, says that the printer that we'll use, will always dot matrix. So I don't think there will be any problem.
May be, I'll try to do some research, how to make an exception if the papersize added, is not supported by the printer.
Thanks for the assistance. Sorry 4 my English

If i want to remove the form altogether will this work or do i have to do anything else
<br />
public static void RemoveCustomPaperSizeFromPrinter(string paperName, string printerName)<br />
{<br />
if (PlatformID.Win32NT == Environment.OSVersion.Platform)<br />
{<br />
const int PRINTER_ACCESS_USE = 0x00000008;<br />
const int PRINTER_ACCESS_ADMINISTER = 0x00000004;<br />
const int FORM_PRINTER = 0x00000002;<br />
<br />
structPrinterDefaults defaults = new structPrinterDefaults();<br />
defaults.pDatatype = null;<br />
defaults.pDevMode = IntPtr.Zero;<br />
defaults.DesiredAccess = PRINTER_ACCESS_ADMINISTER | PRINTER_ACCESS_USE;<br />
<br />
IntPtr hPrinter = IntPtr.Zero;<br />
<br />
if (OpenPrinter(printerName, out hPrinter, ref defaults))<br />
{<br />
try<br />
{<br />
DeleteForm(hPrinter, paperName);<br />
}<br />
catch<br />
{ }<br />
finally<br />
{<br />
ClosePrinter(hPrinter);<br />
}<br />
}<br />
}<br />
}

That looks correct to me. Have you had any luck with it?
|
|
|
|
|
i havent tried it yet to be honest ill let you know how it goes and you can add it to the code if you want.
|
|

|

download link doesnt seem to be working.
I was trying to do this a while back but couldnt figure it out and gave up. Cant wait to see how you approached it.

Thanks for the heads up. Its fixed now
