## Abstract

A printing apparatus includes a printing unit that prints on a roll paper, a transporting unit that transports the roll paper having been printed on along a transport surface, and a drying unit that performs a drying process (post-process) on the roll paper on the transport surface. The drying unit includes a cover (casing) that covers the roll paper on the transport surface. The cover has an inspection window that allows the roll paper on the transport surface to be visually inspected.

## Claims

### Claim 1

A printing apparatus comprising:
a printing unit that prints on a printing medium;
a transporting unit that transports the printing medium having been printed on along a transport surface; and
a post-process unit that performs a post-process on the printing medium on the transport surface,
wherein the post-process unit includes a cover that covers the printing medium on the transport surface, and
wherein the cover has an inspection window that allows the printing medium on the transport surface to be visually inspected.

### Claim 2 (depends on 1)

The printing apparatus according to claim 1,
wherein the post-process unit includes a heating unit that performs a heating process on the printing medium, and
wherein the cover is provided so as to cover the heating unit.

### Claim 3 (depends on 1)

wherein the post-process unit includes a radiating unit that radiates an electromagnetic wave to the printing medium, and
wherein the cover is provided so as to cover the radiating unit.

### Claim 4 (depends on 1)

The printing apparatus according to claim 1, wherein the post-process unit is provided with a shutter capable of covering the inspection window.

### Claim 5 (depends on 1)

The printing apparatus according to claim 1, wherein the inspection window is one of a plurality of inspection windows provided in the cover.

### Claim 6 (depends on 1)
