What if the printer claims to support PCL?
Be very careful if you want to consider a printer that claims to support both HP PCL and GDI. In some cases, the box label claims that both are supported. This may not directly be true. It is common for the PCL support to come in the form of an MS-Windows driver that converts PCL into the printer’s native format. This is of no value unless you are using this driver from within Windows. It is therefore common for the specifications to indicate Supports PCL for MS-DOS under MS-Windows or Supports MS-DOS running under MS-Windows. Those sorts of phrases should be regarded as Warning Labels, indicating that the printer is unlikely ever to be compatible with anything other than the versions of Windows marked on the box.
