We're looking for a custom printer driver or an intercept driver than does what we're asking for below, and then sends the print job to the installed driver.
I think one issue is that writing Windows "printer drivers" is a rare skill. They are typically written using C++. There are some guides and sample code for this from Microsoft, though.
We want to print to our HP T790ps 44in plotter but before the print can happen, we want to query the printer to determine how much paper is remaining on the roll. If there is not enough paper to plot based on the current print request then a pop up must show up instead of printing to warn the user that there is not enough paper on the roll. If there is enough paper on the roll, it just prints without any prompts. We keep printing partial plots and then having to print again (spending lots of $ on partial prints that are useless).
We have a quick VBA snippet that polls the printer to get the remaining paper, so we know the data is available. We just want a seamless solution that when we select the plotter and print if it is all good it prints, if not it does not print and warns why it can't .
