Do you have in the meantime a driver for a higher PCL-level?
I have to correct my previous statement, latest articles from micosoft do only talk about "pcl compatible printers" *not* "pcl3 compatible printers" (WCE6, WEC7, WEC2013). Also i know from one customer which use a pcl6 compatible printer but i was in 2008 so this printer is not available any more.
Do you also provide drivers for further printer languages, e.g. GDI, PS, SPL?
Do you have a list of tested or compatible printers?
We have no list of tested printers and in general we did not know which brands customer use. Best would be select one printer from your office test it then order the latest model and test it again.
