Option attributes for the PaperSize feature
Important
We recommend that you use Microsoft's IPP inbox class driver, along with Print Support Apps (PSA), to customize the print experience in Windows 10 and 11 for printer device development.
For more information, see the Print support app design guide.
The following table lists the attributes associated with the PaperSize feature. For more information about the PaperSize feature, see Standard Features.
All paper size specifications for the following attributes must be expressed relative to PORTRAIT orientation, even if the attributes are being used to describe a different orientation, such as LANDSCAPE.
| Attribute name | Attribute parameter | Comments |
|---|---|---|
| *BottomMargin | Numeric value representing the minimum allowable bottom margin, in x master units, for user-specified paper sizes associated with the CUSTOMSIZE option. Value is relative to the bottom of the physical page. | Optional. If not specified, the default value is 0. Used only with the CUSTOMSIZE option. Portrait orientation is assumed. For more information, see Specifying Paper Sizes. |
| *CenterPrintable? | TRUE or FALSE, indicating whether the value specified by *MaxPrintableWidth is centered. | Optional. If not specified, the printable area is to the right of the margin specified by *MinLeftMargin. Used only with the CUSTOMSIZE option. For more information, see Specifying Paper Sizes. |
| *CursorOrigin | PAIR of numeric values representing the cursor origin position, in master units, where PAIR (0, 0) is the upper left corner. Alternatively for CUSTOMSIZE, specify these values using *CustCursorOriginX and *CustCursorOriginY. | Optional. If not specified, the default value is PAIR (0, 0). Unidrv assumes the cursor origin, relative to the printer, is constant with different paper sizes. |
| *CustCursorOriginX | CUSTOMSIZE parameter expression, used to create a value for the x index of *CursorOrigin. | Optional. Use only with the CUSTOMSIZE option. For more information, see Specifying Paper Sizes. |
| *CustCursorOriginY | CUSTOMSIZE parameter expression, used to create a value for the y index of *CursorOrigin. | Optional. Use only with the CUSTOMSIZE option. For more information, see Specifying Paper Sizes. |
| *CustPrintableOriginX | CUSTOMSIZE parameter expression, used to create a value for the x index of *PrintableOrigin. | Optional. Use only with the CUSTOMSIZE option. For more information, see Specifying Paper Sizes. |
| *CustPrintableOriginY | CUSTOMSIZE parameter expression, used to create a value for the y index of *PrintableOrigin. | Optional. Use only with the CUSTOMSIZE option. For more information, see Specifying Paper Sizes. |
| *CustPrintableSizeX | CUSTOMSIZE parameter expressions, used to create a value for the x value of *PrintableArea. | Optional. Use only with the CUSTOMSIZE option. For more information, see Specifying Paper Sizes. |
| *CustPrintableSizeY | CUSTOMSIZE parameter expression, used to create a value for the y value of *PrintableArea. | Optional. Use only with the CUSTOMSIZE option. For more information, see Specifying Paper Sizes. |
| *MaxSize | PAIR of numeric values representing maximum allowable page length (x) and height (y) values, in master units, for user-specified paper sizes associated with the CUSTOMSIZE option. | Required for the CUSTOMSIZE option. Portrait orientation is assumed. For more information, see Specifying Paper Sizes. |
| *MaxPrintableWidth | Numeric value representing the maximum printable width, in x master units, for user-specified paper sizes associated with the CUSTOMSIZE option. | Required for the CUSTOMSIZE option. Portrait orientation is assumed. For more information, see Specifying Paper Sizes. |
| *MinLeftMargin | Numeric value representing the minimum allowable left margin, in x master units, for user-specified paper sizes associated with the CUSTOMSIZE option. Value is relative to the left edge of the physical page. | Optional. If not specified, the default value is 0. Used only with the CUSTOMSIZE option. Portrait orientation is assumed. For more information, see Specifying Paper Sizes. |
| *MinSize | PAIR of numeric values representing minimum allowable page length (x) and height (y) values, in master units, for user-specified paper sizes associated with the CUSTOMSIZE option. | Required for the CUSTOMSIZE option. Portrait orientation is assumed. For more information, see Specifying Paper Sizes. |
| *PageDimensions | PAIR of numeric values representing the page length (x) and height (y) values, in master units, for any customized options for the PaperSize feature. | Used only for vendor-defined paper sizes. For more information, see Specifying Paper Sizes. |
| *PageProtectMem | Numeric value representing the amount of printer memory, in kilobytes, required to protect a page. | Required if the PageProtect feature is specified. For more information, see Specifying Paper Sizes. |
| *PrintableArea | PAIR of numeric values representing the x- and y-plane lengths, in master units, of the printable page area. | Required for all PaperSize options except CUSTOMSIZE. For more information, see Specifying Paper Sizes. |
| *PrintableOrigin | PAIR of numeric values representing the origin of the printable area, in master units, relative to the upper left-hand corner of the paper. | Required for all PaperSize options except CUSTOMSIZE. For CUSTOMSIZE, you can specify these values using *CustPrintableOriginX and *CustPrintableOriginY. |
| *RotateSize? | TRUE or FALSE, indicating whether Unidrv should rotate the page dimensions because the paper (typically envelopes) is fed in sideways. | Optional. If not specified, the default value is FALSE. Can be used with any standard option for the PaperSize feature, except CUSTOMSIZE. |
| *TopMargin | Numeric value representing the minimum allowable top margin, in y master units, for user-specified paper sizes associated with the CUSTOMSIZE option. Value is relative to the top of the physical page. | Optional. If not specified, the default value is 0. Used only with the CUSTOMSIZE option. Portrait orientation is assumed. For more information, see Specifying Paper Sizes. |
For examples, see the sample GPD files.
CUSTOMSIZE Parameter Expressions
CUSTOMIZE parameter expressions are a restricted form of the command string format. Text strings are not allowed.
Within the expression's ArgumentType segment, the following restrictions apply:
The only ArgumentType value allowed is %d.
Bracketed value ranges are not allowed.
Within the expression's StandardVariableExpression segment, the following restrictions apply:
Only the PhysPaperWidth and PhysPaperLength standard variables can be used.
The Max_Repeat operator is not allowed.
Following are example expressions:
*CustCursorOriginX: %d{((PhysPaperWidth-14040)/2)+300}
*CustCursorOriginY: %d{180}
*CustPrintableOriginX: %d{300}
*CustPrintableOriginY: %d{300}
*CustPrintableSizeX: %d{PhysPaperWidth-600}
*CustPrintableSizeY: %d{PhysPaperLength-600}
