Invalidfont Error when printing..
After upgrading to Windows 7 a couple of users had this error when printing om a Dell 5310n :
Error:Invalidfont Offending command: Show
More programs was affected(e.g. Acrobat , Powerpoint etc.)
Typical the print would print some pages e.g 1-7 and then stop with the error above.
The solution was (on the printserver) to “Download fonts as Type 1” insted of “Choose Download type automatically“
On a DELL 5310 you have to right click on the printer and choose
"Properites"->"printing Preferences"->"Other Options" ->"More Options" ->Fonts (I tried the option to "Download as Type 42" it did not work .)
