TScan
There are two header files that reference the following information. "Printing.h
and "PrintTraps.h" define basically the same information. "Printing.h" provides
glue so that your application can run on 512K Macs that have the old ROM's and
will be running System 3.1 or earlier. If your application does not have to run on
512K Macs (or can't for other reasons), you should use "PrintTraps.h
Type Definitions
TGnlData used in PrGeneral calls. Its fields are set according to the
type of printer being used and the style and resolution of the
output.
TRslRg contains info about range of resolutions achievable by a
particular printer
TRslRec contains actual dot densities that the printer can achieve
TGetRslBlk defines a subsidiary structure used by TGnlData structure
TSetRslBlk defines a subsidiary structure used by TGetRslBlk
TDftBitsBlk defines a subsidiary structure used by TGnlData
TGetRotnBlk defines a subsidiary structure used by TGnlData
TPfPgDir Print information during printing
TPrint the central "print record". See Print Manager
TPrInfo printer information
TPrXInfo additional printer information
TPrPort printer grafPort used in PrOpenDoc, et al.
TPrJob specifics of a print job, filled in via PrJobDialog when you
handle your Print... command.
TPrStl printing style info (eg, lanscape, etc) set via PrStlDialog
when you handle your Page Setup... command
TPrStatus gets filled-in/ updated as PrPicFile executes
TPrDlg superset of a DialogRecord used in PrDlgMain
