A client recently got a new style printer, continuous feed inkjet. I need to re-define page sizes mid-print (print job may have 200+ "pages", each page is one of 10 possible sizes).
Printopen/printsend successfully puts the escape sequences in the print stream, but printdatawindow doesn't print anything. If I skip printsend, then printdatawindow works fine.
Printer is basically brand new to the market (epson colorworks C831). Here's the sample code:
long handle, rtn
handle = printopen("Test Print Job", true)
s = "~h1B(U~h01~255~h05~h1B(C~h02~255~h10~h0E"
// if I comment out this line, and only this line, the datawindow prints normally
rtn = printsend(handle, s, 255)
rtn = printdatawindow(handle, dwc_work_calendar)
Handle returns a valid value, printsend and printdatawindow both show success.
Anyone have any ideas on why printsend is killing the printdatawindow function?
