Few things you can do related to this.
Work around the missing Printer Popup:You can rename the new printer to the old printer name, setup another copy of the printer with old printer name or just leave the old printer installed even though it's missing so you don't get the little pop dialog box that tells you the printers missing. A setting to disable this message would be nice, chances are you will already know what printers are available to you right?
Non-descript Printer NamesWe ran into this same issue years back and decided going forward to just name our plotters and printer with non-descript names like 'Plotter' & 'LaserJet'. It works great, especially when different users print to different printers, so no matter which device their computer is set to print to for 'LaserJet', Datacad just knows the name and the windows printer settings handle sending the prints to the different printers. Yes it was a process for a year or so to update the current working files but once they were set everything going forward uses the non-descript names which makes it nice. We have swapped multiple printers since without a hiccup.
Use Printer Settings and/or Toolbar ButtonsAnother option once you have your workarounds for the old printer info is to setup saved Print settings. We created a drop down toolbar that loads all the settings for our most common printer settings that use the non-descript names (recommended) or the new printer name so we don't have to hassle with adjusting anything in the printer dialogs. If you do not have a printer installed with the name of the old printer, these will not work as they will get stuck on the little popup telling you the printer is missing. If you do have a printer setup with the old name, then you can use these DPS files and/or drop downs to quickly load all your new settings in one single click. The only thing you have to adjust once you have things setup to this point is if a new printer's paper size list is different than the old printers. You can easily just update the DPS files once when this happens.
