System.Drawing.Printing.InvalidPrinterException: Settings to access printer 'PRINTER_NAME' are not valid

[Abhishek R Prajapati]

Hello guys,

I have one windows service which is printing multiple documents based on inputs. My function is performing below actions:

1. Getting list of data based on user inputs(using signalR). No of records can be any numbers from 1 to 5000.

2. Designing label for each record.

3. Print using System.Drawing.Printing.PrintDocument - Print method.

Now for small number of records, the whole process works fine. But with 2000+ records, system throws below exception:

System.Drawing.Printing.InvalidPrinterException: Settings to access printer 'PRINTER_NAME' are not valid.
at System.Drawing.Printing.PrinterSettings.GetHdevmodeInternal(String printer)
at System.Drawing.Printing.PrinterSettings.GetHdevmodeInternal()
at System.Drawing.Printing.PrinterSettings.CreateDeviceContext(PageSettings pageSettings)
at System.Drawing.Printing.PageSettings.get_HardMarginY()

This one comes when I try to access DefaultPageSettings:

var ps = printDocument.PrinterSettings.DefaultPageSettings;
var hardMargin = ps.HardMarginY;

Before fetching records, I tried to access the same settings and I got those settings without any error. So this error comes when I have high number of records.

I have gone through some suggestions on internet like change registery, windows impersonate(tried - no luck) but It is not the case here as It works for small number of records.

Any idea will be highly appreciated.

Thanks,
