Printer Controls (ASP / VBScript)

[Paul White]

I've written a POS system for a client, but we're having problems with the
customer receipt printing. The printer has a left margin gap of about 1
inch. I need to reduce that left margin width in order to prevent
wrap-around.

I have looked up the printer on the web and found a manual for it which
describes the printer escape sequences to send to the printer to control the
left margin, but I'm not sure how to go about it. The printer is a
PP3000UM.

The manual provides the control codes for page layout. The left margin
commands are ...

ESC I " n" --- Set left margin

.... so I assume I need to send a chr(27) & "I" &"1", to make the margin as
small as possible.

Is that right ?

You cannot do anything to the client PC printer from ASP directly(ie change
margins, select trays, etc...). The only way, that I know of, would be to
install an ActiveX component.

Is this a network printer? If so, you could write a PCL file to disk
(server) and then execute a DOS command similiar to: copy /b myreceipt.pcl
//sharename/printername
