Resources statement

The resources statement details the strings needed to be sent to the printer to perform operations such as turning bold on, forcing a new page, setting the printer into landscape mode etc.

The resources statement consists of the set of keyword and string pairs listed in the following table. Note that the EndResources keyword does not have an associated string.

Formally, the syntax is:

resources	resources-label
Reset	reset-string
SetPageSize	page-size-string
PreAmble	preamble-string
PostAmble	postamble-string
SetTextColor	text-color-string
BoldOn	bold-on-string
BoldOff	bold-off-string
ItalicOn	italic-on-string
ItalicOff	italic-off-string
UnderlineOn	underline-on-string
UnderlineOff	underline-off-string
StrikethroughOn	underline-on-string
StrikethroughOff	underline-off-string
NewPage	new-page-string
Portrait	set-portrait-mode-string
Landscape	set-landscape-mode-string
SetXPos	set-x-pos-string
SetYPos	set-y-pos-string
IncrementXPos	increment-x-pos-string
IncrementYPos	increment-y-pos-string
CarriageReturn	carriage-return-string
SetGraphicsColor	graphics-color -string
BitmapStart	bitmap-start-string
BitmapEnd	bitmap-end-string
Scanline	bitmap-scanline-string
EndScanline	bitmap-end-scanline-string
BitmapEnd	bitmap-end-string
EndResources

All attributes within a resources statement are strings enclosed in a pair of double quotes. For example:

SetPageSize         "<27>C<0>%c"
PreAmble            "<27>l<0><27>N<0><27>+<2><27>x<1>"
PostAmble           "<13><27>@"
BoldOn              "<27>G"
BoldOff             "<27>H"

Parameters can also be included in attribute strings, for example %c in the SetPageSize string.

Different printers may implement different numbers of resource strings — for example:

page printers do not need to support CarriageReturn
a printer may not support strikethrough, so its resources statement would not include StrikethroughOn and StrikethroughOff.

There are also eight numbered resources, Resource1 to Resource8, which can be included in the resource statement.
