Troubleshooting 'Typecheck' Error in mprint.umich.edu Printing

Environment

MPrint 

Issue

I'm trying to print a document through mprint.umich.edu, but I keep getting an error that says "Error: typecheck; Offending Command: known".

Resolution

First, check if the PDF or print job contains charts or graphs. If it does, try the following steps:

  1. Print the graph/chart pages individually.
    1. For example, if the job completes pages 1-5 and there are ten pages total with a chart on page 6, print page 6 individually and then try printing pages 7-10.

If the document does not contain charts or graphs, follow these basic troubleshooting steps:

  1. Try a different browser or an incognito window.
  2. Attempt to print directly from the machine using Ctrl + P (Windows) or Command + P (Mac).
  3. Try breaking the PDF in half and printing each half separately.
