lPaperDimensions.X excceds range of FPDevMode^.dmPaperWidth (ppPrintr.pas)

rbuser

Hi,

some of our customers get a ERangeExcpetion on trying to print a report
from a archive. Previewing before generating archive and after loading
works fine, but direct printing fails.
After debuging i detected that the critical line is
ppPrintr.pas (6625): FPDevMode^.dmPaperWidth := lPaperDimensions.X;
dmpaperWidth is a smallint, lPaperDimensions.X is sometime 53340 which
is larger than a smallint

Normally lPaperDimension.x is 2100 = 10 *210mm, which is the width of
germand DIN A4 in Portrait mode.

The resulting value 53340= 10 * 210mm * 10 * 2,54 , where 2,54 is 1
inch
in cm.

Any idea how and why this conversion is happening?

Obviously it is depending on printers settings.
One customer get this error on selecting a OKI printer but not using a
Brother printer on the same station.
Other customers can print archive an station A but not on station B
using the same printer.

Reinstalling any printer drivers did not solve the problem!

Hi Carsten,

This is not a known issue.

The Win API defines the DevMode.PaperWidth as Short (Smallint). The units
are MM tenths. The A4 value should be 2100 = 210 * 10. I have no clue why
the value would be otherwise.

If you would like to provide an example project I can build and run in the
debugger, I can research it. I can download and install a specific printer
driver if needed. Please use standard Delphi components and RB. Send in zip
format - include only .dpr, .pas, .dfm. Send to support@




Best regards,
