Customsize GPD Driver for Printer questions..

[dakotauk]

Im currently in the process of editting a .GPD file to enable a custom print size which is not avaialable on the print options.

I have create a new form in print server properties and this is still being over written by the print driver.

I would like to know two (probably basic) by none the least questions:

Im looking to create a custom size of 11cm x 4cm

1. what are the units used in the below example of the current .gpd file. I have tried all different conversion and still have yet to recieve a logical answer.

*MinSize: PAIR(1275, 992)
*MaxSize: PAIR(3643, 7920)

2. why does the above state PAIR and why two values for both sizes??

FULL DRIVER

*Option: CUSTOMSIZE
{
*rcNameID: =USER_DEFINED_SIZE_DISPLAY
*MinSize: PAIR(1275, 992)
*MaxSize: PAIR(3643, 7920)
*MaxPrintableWidth: 3643
*MinLeftMargin: 43
*CenterPrintable?: FALSE
*TopMargin: 60
*BottomMargin: 60
*CustCursorOriginX: %d{43}
*CustCursorOriginY: %d{60}
*CustPrintableOriginX: %d{43}
*CustPrintableOriginY: %d{60}
*CustPrintableSizeX: %d{PhysPaperWidth-86}
*CustPrintableSizeY: %d{PhysPaperLength-120}
*Command: CmdSelect

Sorry if this easier than it appears to me, its completely thrown me..

Any help would be great

Best Regards
