I am seeing some strange errors in printing labels. There is no problem with spacing on the labels, Avery 5167. However in printing a sheet of labels, the print preview will be fine. However at some point the font size information will be lost. For instance if the item code and item name are in 8pt and the price is 12pt, the print size will revert to 10pt but with the spacing of the correct font, so the item code and item name are crunched together, and the price is spaced out. This starts happening randomly. Also the last label will print out with only the price and barcode. The barcode always prints correctly.
I am currently using a Ricoh Aficio SP C431DN connected via USB (the problem is the same if using a network connection), with the latest printer drivers, but the problem also occurs with various model HP printers.
